This specifies the name of the volume that is to be created. A volume's name must start with an alphabetic character (a to z or A to Z) and be 197 or fewer characters in length for FlexGroups, and 203 or fewer characters in length for all other volume types. Volume names must be unique within a Vserver.

{ [-aggregate <aggregate name>] - Aggregate Name

This specifies the storage aggregate on which the volume is to be created. This parameter only applies to FlexVol volumes.

| [-aggr-list <aggregate name>,…​] - List of Aggregates for FlexGroup Constituents

Specifies an array of names of aggregates to be used for FlexGroup constituents. Each entry in the list will create a constituent on the specified aggregate. The root constituent will always be placed on the first aggregate in the list, unless optimize-aggr-list is specified as true . An aggregate may be specified multiple times to have multiple constituents created on it. This parameter only applies to FlexGroups.

[-aggr-list-multiplier <integer>] - Aggregate List Repeat Count

Specifies the number of times to iterate over the aggregates listed with the -aggr-list parameter when creating a FlexGroup. The aggregate list will be repeated the specified number of times. Example:

-aggr-list aggr1,aggr2 -aggr-list-multiplier 2

will cause four constituents to be created in the order aggr1 , aggr2 , aggr1 , aggr2 .

+
The default value is 4.

+
This parameter only applies to FlexGroups.

[-optimize-aggr-list {true|false}] - Have the System Optimize the Order of the Aggregate List

Specifies whether to create the constituents of the FlexGroup volume on the aggegates specified in the aggr-list in the order they are specified, or whether the system should optimize the ordering of the aggregates. If this value is true , the system will optimize the ordering of the aggregates specified in the aggr-list . If this value is false the order of the aggr-list will be unchanged. The default value is false . This parameter only applies to FlexGroups.

| [-auto-provision-as <FlexGroup>] - Automatically Provision as Volume of Type

Use this parameter to automatically select existing aggregates for provisioning FlexGroup volumes. Note that the fastest aggregate type with at least one aggregate on each node of the cluster will be selected. When auto provisioning a FlexGroup volume, the size of the FlexGroup volume should be a minimum of 800 GB per node.

When the UDO License is installed, this will be the default for volume creation if neither the aggregate nor aggr-list parameters are specified.

This parameter only applies to FlexGroups.

[-support-tiering {true|false}] - Automatically Provision FlexGroup on FabricPools

This parameter specifies whether or not FabricPools are selected when provisioning a FlexGroup during the protection workflows using the auto-provision-as parameter. Only FabricPool aggregates are used if this parameter is set to true and only non FabricPool aggregates are used if this parameter is set to false. Tiering support for a FlexGroup can be changed by moving all of the constituents to the required aggregates. The default value is false

This parameter only applies to FlexGroups created using the -auto-provision-as parameter.

[-use-mirrored-aggregates {true|false}] - Automatically Provision FlexGroup on Mirrored Aggregates

Use this parameter to specify whether mirrored aggregates are selected when creating a FlexGroup using the auto-provision-as parameter. Only mirrored aggregates are used if this parameter is set to true and only unmirrored aggregates are used if this parameter is set to false. Aggregate level mirroring for a FlexGroup can be changed by moving all of the constituents to the required aggregates. The default value is true for a MetroCluster configuration and is false for a non-MetroCluster configuration

This parameter only applies to FlexGroups created using the -auto-provision-as parameter.

[-encryption-type {none|volume|aggregate|mixed}] - Encryption Type

Use this parameter to specify the encryption-type while creating a FlexGroup using the auto-provision-as parameter. If the value is none , the FlexGroup created will be unencrypted. If the value is volume , the FlexGroup created will be of type NVE (NetApp Volume Encryption) and if the value is aggregate , the FlexGroup created will be of type NAE (NetApp Aggregate Encryption).

This parameter only applies to FlexGroups created using the -auto-provision-as parameter.

[-nodes {<nodename>|local}] - List of Nodes Hosting the Volume }

Specifies an array of node names to be used for provisioning the FlexGroup. If an array of node names is specified, only aggregates from the specified nodes will be considered for provisioning. If no value is specified, all nodes in the cluster will be used.

[-size {<integer>[KB|MB|GB|TB|PB]}] - Volume Size

This optionally specifies the size of the volume. The size is specified as a number followed by a unit designation: k (kilobytes), m (megabytes), g (gigabytes), or t (terabytes). If the unit designation is not specified, bytes are used as the unit, and the specified number is rounded up to the nearest 4 KB. The minimum size for a FlexVol volume is 20 MB. The minimum size for a volume guaranteed FlexGroup is 20 MB per constituent. The minimum size for a none guaranteed FlexGroup is 200 MB per constituent. However, the recommended size for all FlexGroups is a minimum of 100 GB per constituent. For all volumes, the default size is set to the minimum size. The volume's maximum size is limited by the platform maximum. If the volume's guarantee is set to volume , the volume's maximum size can also be limited by the available space in the hosting aggregates. Volumes can be increased and decreased in size with the volume modify command. The maximum number of files a volume is configured for is listed under "Total Files" when running the command volume show-instance .

[-state {online|restricted|offline|force-online|force-offline|mixed}] - Volume State

This optionally specifies the volume's state. A restricted volume does not provide client access to data but is available for administrative operations.

Note The mixed state applies to FlexGroups only and cannot be specified as a target state.
[-policy <text>] - Export Policy

This optionally specifies the ID number of the export policy associated with the volume. For information on export policies, see the documentation for the vserver export-policy create command. FlexGroups do not support policies that allow NFSv4 protocol access.

[-user <user name>] - User ID

This optionally specifies the name or ID of the user that is set as the owner of the volume's root.

[-group <group name>] - Group ID

This optionally specifies the name or ID of the group that is set as the owner of the volume's root.

[-security-style <security style>] - Security Style

This optionally specifies the security style for the volume. Possible values include unix (for UNIX mode bits), ntfs (for CIFS ACLs), mixed (for mixed NFS and CIFS permissions) and unified (for mixed NFS and CIFS permissions with unified ACLs). Regardless of the security style, both NFS and CIFS clients can read from and write to the volume.

[-unix-permissions <unix perm>] - UNIX Permissions

This optionally specifies the default UNIX permissions for files on the volume. Specify UNIX permissions either as a four-digit octal value (for example, 0700) or in the style of the UNIX ls command (for example, -rwxr-x---). For information on UNIX permissions, see the UNIX or Linux documentation. The default setting is 0755 or ---rwxr-xr-x.

[-junction-path <junction path>] - Junction Path

This optionally specifies the volume's junction path. The junction path name is case insensitive and must be unique within a Vserver's namespace.

[-junction-active {true|false}] - Junction Active (privilege: advanced)

This optionally specifies whether the volume's junction path is active. The default setting is true . If the junction path is inactive, the volume does not appear in the Vserver's namespace. This parameter is available only at the advanced privilege level and higher.

[-vsroot {true|false}] - Vserver Root Volume (privilege: advanced)

This optionally specifies whether the volume is the root volume of its Vserver. The default setting is false . If this parameter is set to true, the default size of the newly created volume is 1GB. This parameter is not supported on FlexGroups.

[-comment <text>] - Comment

This optionally specifies a comment for the volume.

[-max-autosize {<integer>[KB|MB|GB|TB|PB]}] - Maximum Autosize

This parameter allows the user to specify the maximum size to which a volume can grow. The default for volumes is 120% of the volume size. If the value of this parameter is invalidated by manually resizing the volume, the maximum size is reset to 120% of the volume size. The value for -max-autosize cannot be set larger than the platform-dependent maximum volume size. If you specify a larger value, the value of -max-autosize is automatically reset to the supported maximum without returning an error.

[-min-autosize {<integer>[KB|MB|GB|TB|PB]}] - Minimum Autosize

This parameter specifies the minimum size to which the volume can automatically shrink. If the volume was created with the grow_shrink autosize mode enabled, then the default minimum size is equal to the initial volume size. If the value of the -min-autosize parameter is invalidated by a manual volume resize, the minimum size is reset to the volume size.

[-autosize-grow-threshold-percent <percent>] - Autosize Grow Threshold Percentage

This parameter specifies the used space threshold for the automatic growth of the volume. When the volume’s used space becomes greater than this threshold, the volume will automatically grow unless it has reached the maximum autosize.

[-autosize-shrink-threshold-percent <percent>] - Autosize Shrink Threshold Percentage

This parameter specifies the used space threshold for the automatic shrinking of the volume. When the amount of used space in the volume drops below this threshold, the volume will shrink unless it has reached the specified minimum size.

[-autosize-mode {off|grow|grow_shrink}] - Autosize Mode

This parameter specifies the autosize mode for the volume. The supported autosize modes are:

  • off - The volume will not grow or shrink in size in response to the amount of used space.

  • grow - The volume will automatically grow when used space in the volume is above the grow threshold.

  • grow_shrink - The volume will grow or shrink in size in response to the amount of used space.

By default, -autosize-mode is off for new volumes, except for data protection mirrors, for which the default value is grow_shrink . The grow and grow_shrink modes work together with Snapshot autodelete to automatically reclaim space when a volume is about to become full. The volume parameter -space-mgmt-try-first controls the order in which these two space reclamation policies are attempted.

[-files-set-maximum {true|false}] - Set Total Files (for user-visible data) to the Highest Value that the Volume can Hold (privilege: advanced)

This optionally specifies whether the volume's total number of files will be set to the highest possible value. By default, it is false . If true , the volume's total number of files is set to the highest value that the volume can hold.

[-maxdir-size {<integer>[KB|MB|GB|TB|PB]}] - Maximum Directory Size (privilege: advanced)

This optionally specifies the maximum directory size. The default maximum directory size is model-dependent and optimized for the size of system memory.

{ [-space-slo {none|thick|semi-thick}] - Space SLO

This optionally specifies the Service Level Objective for space management (the space SLO setting) for the volume. The space SLO value is used to enforce volume settings so that sufficient space is set aside to meet the space SLO. The default setting is none . There are three supported values: none , thick and semi-thick .

  • none : The value of none does not provide any guarantee for overwrites or enforce any restrictions. It should be used if the admin plans to manually manage space consumption in the volume and aggregate, and out of space errors.

  • thick : The value of thick guarantees that the hole fills and overwrites to space-reserved files in this volume will always succeed by reserving space. To meet this space SLO, the following volume-level settings are automatically set and cannot be modified:

  • Space Guarantee: volume - The entire size of the volume is preallocated in the aggregate. Changing the volume's space-guarantee type is not supported.

  • Fractional Reserve: 100 - 100% of the space required for overwrites is reserved. Changing the volume's fractional-reserve setting is not supported.

  • semi-thick : The value of semi-thick is a best-effort attempt to ensure that overwrites succeed by restricting the use of features that share blocks and auto-deleting backups and Snapshot copies in the volume. To meet this space SLO, the following volume-level settings are automatically set and cannot be modified:

  • Space Guarantee: volume - The entire size of the volume is preallocated in the aggregate. Changing the volume's space-guarantee type is not supported.

  • Fractional Reserve: 0 - No space will be reserved for overwrites by default. However, changing the volume's fractional-reserve setting is supported. Changing the setting to 100 means that 100% of the space required for overwrites is reserved.

  • Snapshot Autodelete: enabled - Automatic deletion of Snapshot copies is enabled to reclaim space. To ensure that the overwrites can be accommodated when the volume reaches threshold capacity, the following volume Snapshot autodelete parameters are set automatically to the specified values and cannot be modified:

  • enabled : true

  • commitment : destroy

  • trigger : volume

  • defer-delete : none

  • destroy-list : vol_clone , lun_clone , file_clone , cifs_share

    In addition, with a value of ``_semi-thick_`` , the following technologies are not supported for the volume:

  • File Clones with autodelete disabled: Only full file clones of files, LUNs or NVMe namespaces that can be autodeleted can be created in the volume. The use of autodelete for file clone create is required.

  • Partial File Clones: Only full file clones of files or LUNs that can be autodeleted can be created in the volume. The use of range for file clone create is not supported.

  • Volume Efficiency: Enabling volume efficiency is not supported to allow autodeletion of Snapshot copies.

| [-s, -space-guarantee {none|volume}] - Space Guarantee Style

This optionally specifies the space guarantee style for the volume. A value of volume reserves space on the aggregates for the entire volume. A value of none reserves no space on the aggregates, meaning that writes can fail if an aggregate runs out of space. The default setting for the volumes on All Flash FAS systems is none , otherwise the default setting is volume . The file setting is no longer supported.

[-type {RW|DP}] - Volume Type }

This optionally specifies the volume's type, either read-write (RW) or data-protection (DP). If you do not specify a value for this parameter, a RW volume is created by default.

[-snapdir-access {true|false}] - Snapshot Directory Access Enabled

This optionally specifies whether clients have access to .snapshot directories. The default setting is true .

[-percent-snapshot-space <percent>] - Space Reserved for Snapshot Copies

This optionally specifies the amount of space that is reserved in the volume for Snapshot copies. The default setting is 5 percent, except for data protection mirrors for which the default is 0 percent.

[-snapshot-policy <snapshot policy>] - Snapshot Policy

This optionally specifies the Snapshot policy for the volume. The default is the Snapshot policy for all volumes on the Vserver, as specified by the -snapshot-policy parameter of the vserver create and vserver modify commands. The schedules associated with the snapshot-policy for a FlexGroup cannot have an interval shorter than 30 minutes.

[-language <Language code>] - Language

This optionally specifies the language encoding setting for the volume. By default, the volume inherits the Vserver language encoding setting.

Note You cannot modify the language encoding setting of a volume.
[-foreground {true|false}] - Foreground Process

This specifies whether the operation runs in the foreground. The default setting is true (the operation runs in the foreground). When set to true, the command will not return until the operation completes. This parameter applies only to FlexGroups. For FlexVol volumes, the command always runs in the foreground.

[-nvfail {on|off}] - NVFAIL Option

Setting this optional parameter to true causes the volume to set the in-nvfailed-state flag to true, if committed writes to the volume are lost due to a failure. The in-nvfailed-state flag fences the volume from further data access and prevents possible corruption of the application data. Without specifying a value, this parameter is automatically set to false.

[-constituent-role <Constituent Roles>] - Constituent Volume Role

This parameter is no longer supported.

{ [-qos-policy-group <text>] - QoS Policy Group Name

This optional parameter specifies which QoS policy group to apply to the volume. This policy group defines measurable service level objectives (SLOs) that do not adjust based on the volume allocated space or used space. If you do not assign a policy group to a volume, the system will not monitor and control the traffic to it.

| [-qos-adaptive-policy-group <text>] - QoS Adaptive Policy Group Name }

This optional parameter specifies which QoS adaptive policy group to apply to the volume. This policy group defines measurable service level objectives (SLOs) and Service Level Agreements (SLAs) that adjust based on the volume allocated space or used space.

[-caching-policy <text>] - Caching Policy Name

This optionally specifies the caching policy to apply to the volume. A caching policy defines how the system caches this volume's data in a Flash Pool aggregate or Flash Cache modules. If a caching policy is not assigned to this volume, the system uses auto as the default caching policy.

Both metadata and user data are eligible for caching. Metadata consists of directories, indirect blocks and system metafiles. They are eligible for read caching only. When a random write pattern is detected on user data, the first such write is eligible for read caching while all subsequent overwrites are eligible for write caching. The available caching policies are:

  • none - Does not cache any user data or metadata blocks.

  • auto - Read caches all metadata and randomly read user data blocks, and write caches all randomly overwritten user data blocks.

  • meta - Read caches only metadata blocks.

  • random_read - Read caches all metadata and randomly read user data blocks.

  • random_read_write - Read caches all metadata, randomly read and randomly written user data blocks.

  • all_read - Read caches all metadata, randomly read and sequentially read user data blocks.

  • all_read_random_write - Read caches all metadata, randomly read, sequentially read and randomly written user data.

  • all - Read caches all data blocks read and written. It does not do any write caching.

  • noread-random_write - Write caches all randomly overwritten user data blocks. It does not do any read caching.

  • meta-random_write - Read caches all metadata and write caches randomly overwritten user data blocks.

  • random_read_write-random_write - Read caches all metadata, randomly read and randomly written user data blocks. It also write caches randomly overwritten user data blocks.

  • all_read-random_write - Read caches all metadata, randomly read and sequentially read user data blocks. It also write caches randomly overwritten user data blocks.

  • all_read_random_write-random_write - Read caches all metadata, randomly read, sequentially read and randomly written user data. It also write caches randomly overwritten user data blocks.

  • all-random_write - Read caches all data blocks read and written. It also write caches randomly overwritten user data blocks.

Note that in a caching-policy name, a hyphen (-) separates read and write policies. Default caching-policy is auto.

[-cache-retention-priority {normal|low|high}] - Cache Retention Priority (privilege: advanced)

This optionally specifies the cache retention priority to apply to the volume. A cache retention priority defines how long the blocks of a volume will be cached in flash pool once they become cold. If a cache retention priority is not assigned to this volume, the system uses the default policy. This parameter is available only at the advanced privilege level and higher.

The available cache retention priority are:

  • low - Cache the cold blocks for the lowest time.

  • normal - Cache the cold blocks for the default time.

  • high - Cache the cold blocks for the highest time.

[-is-autobalance-eligible {true|false}] - Is Eligible for Auto Balance Aggregate (privilege: advanced)

If the Auto Balance feature is enabled, this parameter specifies whether the volume might be considered for system workload balancing. When set to true , the Auto Balance Aggregate feature might recommend moving this volume to another aggregate. The default value is true .

[-max-constituent-size {<integer>[KB|MB|GB|TB|PB]}] - Maximum size of a FlexGroup Constituent (privilege: advanced)

This optionally specifies the maximum size of a FlexGroup constituent. The default value is determined by checking the maximum FlexVol size setting on all nodes used by the FlexGroup. The smallest value found is selected as the default for the -max-constituent-size for the FlexGroup. This parameter applies to FlexGroups only.

[-efficiency-policy <efficiency policy>] - Storage Efficiency Policy (privilege: advanced)

This optionally specifies which storage efficiency policy to apply to the volume. This parameter is applicable only for All-Flash FAS. This parameter is not supported on data protection volumes on any platform. To disable all efficiency features on the volume in All-Flash FAS, use the value none . The default value is auto . The policies inline-only and none are not supported on Capacity optimized Flash with QAT supported platforms.

[-snaplock-type {non-snaplock|compliance|enterprise}] - SnapLock Type

This optionally specifies the SnapLock type of the volume. The default value is non-snaplock .

[-vserver-dr-protection {protected|unprotected}] - Vserver DR Protection

This optionally specifies whether the volume should be protected by Vserver level SnapMirror. This parameter is applicable only if the Vserver is the source of a Vserver level SnapMirror relationship. The default value for a volume of type “RW” is protected .

[-encrypt {true|false}] - Enable or Disable Encryption

This parameter allows the user to create an encrypted volume. When it is set to true , a new key is generated, and the volume is encrypted using the generated key. When it is set to false , the volume created is unencrypted.

[-is-space-reporting-logical {true|false}] - Logical Space Reporting

This optionally specifies whether to report space logically on the volume. When space is reported logically, ONTAP reports the volume space such that all the physical space saved by the storage efficiency features are also reported as used. The default setting is false .

[-is-space-enforcement-logical {true|false}] - Logical Space Enforcement

This optionally specifies whether to perform logical space accounting on the volume. When space is enforced logically, ONTAP enforces volume settings such that all the physical space saved by the storage efficiency features will be calculated as used. The default setting is false .

[-tiering-policy <Tiering Policy>] - Volume Tiering Policy

This optional parameter specifies the tiering policy to apply to the volume. This policy determines whether the user data blocks of a volume in a FabricPool will be tiered to the cloud tier when they become cold. FabricPool combines Flash (performance tier) with an object store (cloud tier) into a single aggregate. The default tiering policy is snapshot-only for a FlexVol and none for a FlexGroup. Temperature of a volume block increases if it is accessed frequently and decreases when it is not.

The available tiering policies are:

  • snapshot-only - This policy allows tiering of only the volume Snapshot copies not associated with the active file system. The default minimum cooling period is 2 days. The -tiering-minimum-cooling-days parameter can be used to override the default.

  • auto - This policy allows tiering of both Snapshot copy data and active file system user data to the cloud tier. The default cooling period is 31 days. The -tiering-minimum-cooling-days parameter can be used to override the default.

  • none - Volume blocks will not be tiered to the cloud tier.

  • all - This policy allows tiering of both Snapshot copy data and active file system user data to the cloud tier as soon as possible without waiting for a cooling period. On DP volumes, this policy allows all transferred user data blocks to start in the cloud tier.

[-cloud-retrieval-policy {default|on-read|never|promote}] - Volume Cloud Retrieval Policy (privilege: advanced)

This optional parameter specifies the cloud retrieval policy for the volume. This policy determines which tiered out blocks to retrieve from the capacity tier to the performance tier.

The available cloud retrieval policies are:

  • default - This policy retrieves tiered data based on the underlying tiering policy. If the tiering policy is 'auto', tiered data is retrieved only for random client driven data reads. If the tiering policy is 'none' or 'snapshot-only', tiered data is retrieved for random and sequential client driven data reads. If the tiering policy is 'all', tiered data is not retrieved.

  • on-read - This policy retrieves tiered data for all client driven data reads.

  • never - This policy never retrieves tiered data.

  • promote - This policy retrieves all eligible tiered data automatically during the next scheduled scan. It is only supported when the tiering policy is 'none' or 'snapshot-only'. If the tiering policy is 'snapshot-only', the only data brought back is the data in the AFS. Data that is only in a snapshot copy stays in the cloud.

[-tiering-minimum-cooling-days <integer>] - Volume Tiering Minimum Cooling Days (privilege: advanced)

This optional parameter specifies the minimum number of days that user data blocks of the volume must be cooled before they can be considered cold and tiered out to the cloud tier. For volumes hosted on FabricPools, this parameter is used for tiering purposes and does not affect the reporting of inactive data. For volumes hosted on non-FabricPools, this parameter affects the cooling window used for the reporting of inactive data. The value specified should be greater than the frequency with which applications in the volume shift between different sets of data. Valid values are between 2 and 183. This parameter cannot be set when volume tiering policy is either "none" or "all". The default value of this parameter depends on the volume's tiering policy. See the tiering policy section of this documentation for corresponding default values. If the tiering policy on the volume gets changed, then this parameter will be reset to the default value corresponding to the new tiering policy.

[-tiering-object-tags <text>,…​] - Tags to be Associated with Objects Stored on a FabricPool

This optional parameter specifies tiering object tags to be associated with objects stored on a FabricPool.

Object tags should follow these rules:

  • Each object tag should be a key-value pair separated by '='.

  • Mulitple tags should be separated by ','. Overall tags should be in format key1=value1[,key2=value2,…​].

  • All tags of a volume must have a unique key.

  • Each tag key should start with either a letter or an underscore. Keys should contain only alphanumeric characters and underscores. Maximum allowed limit is of 127 characters.

  • Each tag value should be of maximum 127 characters consisting of only alphanumeric characters and underscores.

  • Maximum 4 object tags are allowed per volume.

{ [-application-io-size <Application I/O Size>] - Block Size to Use by Compression (privilege: advanced)

This optionally specifies the application IO size to apply to the volume. This parameter specifies the compression group size for enabling compression on the volume. This parameter is applicable only for All Flash FAS. This parameter is not supported on data protection volumes on any platform.

The available application I/O Sizes are:

  • 8K

  • auto - ONTAP will select compression group size automatically, based on temperature of the block.

[-storage-efficiency-mode {default|efficient}] - Storage Efficiency Mode

This optionally specifies efficiency mode of the volume.

The available efficiency modes are:

  • default

  • efficient

The default mode sets 8k adaptive compression on the volume. The efficient mode sets auto adaptive compression on the volume. This parameter is supported only on AFF platform. Auto adaptive compression will be set on QAT supported platforms irrespective of the modes.

[-analytics-state <Analytics State>] - File System Analytics State

This optionally specifies whether the volume will keep track of file system usage for the purpose of analytics. The default value is off .

[-activity-tracking-state <Activity Tracking State>] - Activity Tracking State

This optionally specifies whether the volume will keep track of volume activity, in real time. Tracked activities include read and write traffic for files, directories, users and clients. The default value is off .

[-key-manager-attribute <text>] - Key Manager Attribute

This optional parameter specifies an additional key manager attribute that should be an identifier-value pair separated by '=', ex. CRN=my-unique-value

The following identifiers are currently supported:

  • CRN

[-anti-ransomware-state {disabled|enabled|dry-run|paused|dry-run-paused|enable-paused|disable-in-progress}] - Anti-ransomware State

Use this parameter to specify the anti-ransomware-state while creating a volume. If the value is disabled , the volume created will have anti-ransomware feature disabled. If the value is enabled , the volume created will have anti-ransomware feature enabled and if the value is dry-run , the volume created will be in the anti-ransomware evaluation mode.

[-granular-data {disabled|basic}] - Granular data

This parameter specifies the type of granular data storage supported on the volume. Once this property is changed to any value other than disabled on a volume, it cannot be disabled on that volume using this parameter. It can only be disabled on that volume by restoring a Snapshot copy. This property is only supported on FlexGroup volumes. The default value is basic for AWS S3 FlexGroup volumes and disabled otherwise. Files modified by the granular data algorithms use granular data, which might impact read/write I/O performance.

The available options are:

  • disabled - No volume capacity rebalancing operations are performed.

  • basic - Volume capacity rebalancing operations are enabled.

[-atime-update-period <integer>] - Access Time Update Period (Seconds) (privilege: advanced)

This parameter specifies the time period that must be elapsed in between consecutive atime update events. Note: The value of this parameter is only used if -atime-update is enabled on the volume.

[-snapshot-locking-enabled {true|false}] - Enable Snapshot Copy Locking

This parameter specifies whether the Snapshot copy locking feature is enabled, based on an independent compliance-clock time. Once this property is enabled, it cannot be disabled and the volume cannot be deleted until all locked Snapshot copies are past their expiry time. The default value is false.

[-is-large-size-enabled {true|false}] - Are Large Size Volumes and Files Enabled

This parameter specifies whether support for large Flexible volumes and large files is enabled. If this value is true, the maximum volume size for a Flexible volume will be 300TB and the maximum size of a single file will be 128TB. If this value is false, the maximum volume size for a Flexible volume will be 100TB and the maximum size of a single file will be 16TB. The default value is false.

[-is-preserve-unlink-enabled {true|false}] - Is Preserve Unlink Enabled (privilege: advanced)

This parameter specifies whether preserve unlink is enabled for NFSV4.1 shares on the volume. Once this feature is enabled, a file removal op on a file with existing share locks will result in the file being moved to the trash directory. Clients will continue to be able to access the file using its file handle. The last close for that file will result in deletion of the file. The default value is false.

[-is-cloud-write-enabled {true|false}] - Is Cloud Write Enabled (privilege: advanced)

This parameter specifies whether cloud write is enabled on the volume. This feature is only available on volumes in FabricPools. The default value is false.

[-aggressive-readahead-mode {none|file_prefetch}] - Aggressive readahead mode (privilege: advanced)

This parameter specifies the aggressive readahead mode of the volume. Possible values are none and file_prefetch . When set to file_prefetch , on a file read, the system aggressively issues readaheads for all of the blocks in the file and retains those blocks in a cache for a finite period of time. This feature is only available on FabricPool volumes on FSx for ONTAP and Cloud Volumes ONTAP. The default value is none .

[-in-consistency-group {true|false}] - If this Volume is part of a Consistency Group

This parameter specified if this volume is associated with a consistency group.

Examples

The following example creates a new volume named user_jdoe on a Vserver named vs0 and a storage aggregate named aggr1. Upon its creation, the volume is placed in the online state. It uses the export policy named default_expolicy. The owner of the volume's root is a user named jdoe whose primary group is named dev. The volume's junction path is /user/jdoe. The volume is 250 GB in size, space for the entire volume is reserved on the aggregate, and the create operation runs in the background.

cluster1::> volume create -vserver vs0 -volume user_jdoe -aggregate aggr1
            -state online -policy default_expolicy -user jdoe -group dev
            -junction-path /user/jdoe -size 250g  -space-guarantee volume
            -percent-snapshot-space 20 -foreground false

The following example creates a new volume named vol_cached on a Vserver named vs0 and a Flash Pool storage aggregate named aggr1. The newly created volume is placed online and uses auto as the caching policy.

cluster1::> volume create -vserver vs0 -volume vol_cached -aggregate aggr1
            -state online -caching-policy auto

The following example creates a new FlexGroup named media_vol on a Vserver named vs0 with four constituents on aggregates aggr1 and aggr2. Upon its creation, the volume is placed in the online state. The volume's junction path is /media. The volume is 200 TB in size, no space for the volume is reserved on the aggregates, and the create operation runs in the background.

cluster1::> volume create -vserver vs0 -volume media_vol
            -aggr-list aggr1,aggr1,aggr2,aggr2 -junction-path /media -size 200TB
            -space-guarantee none -foreground false

The following example creates a new FlexGroup volume named fg on a Vserver named vs0 on aggregates selected by Data ONTAP.

cluster1::> volume create -vserver vs0 -volume fg -auto-provision-as flexgroup
