Display space usage for volume(s)

Availability: This command is available to cluster and Vserver administrators at the admin privilege level.

Description

The volume show-space command displays information about space usage within the volume. The command output depends on the parameter or parameters specified with the command. If no parameters are specified, the command displays the following information about all volumes.

Parameters

{ [-fields <fieldname>,…​]

If you specify the -fields <fieldname>, …​ parameter, the command output also includes the specified field or fields. You can use '-fields ?' to display the fields to specify.

| [-instance ] }

If you specify the -instance parameter, the command displays detailed information about all fields.

[-vserver <vserver name>] - Vserver

If this parameter and the -volume parameter are specified, the command displays detailed information about the specified volume. If this parameter is specified by itself, the command displays information about volumes on the specified Vserver.

[-volume <volume name>] - Volume Name

If this parameter and the -vserver parameter are specified, the command displays detailed information about the specified volume. If this parameter is specified by itself, the command displays information about all volumes matching the specified name.

[-volume-msid <integer>] - Volume MSID

If this parameter is specified, the command displays information only about the volume that has the specified MSID.

[-volume-dsid <integer>] - Volume DSID

If this parameter is specified, the command displays information only about the volume that has the specified DSID.

[-vserver-uuid <UUID>] - Vserver UUID

If this parameter is specified, the command displays information only about the volume on the vserver which has the specified UUID.

[-aggregate <aggregate name>] - Aggregate Name

If this parameter is specified, the command displays information only about the volumes that are associated with the specified aggregate.

If this parameter is specified, the command displays information only about the volumes that belong to the specified host.

[-user-data {<integer>[KB|MB|GB|TB|PB]}] - User Data

If this parameter is specified, the command displays information only about the volume or volumes that have the specified amount of space in use by user data in the volume.

This is the amount of data written to the volume via CIFS, NFS or SAN protocols plus the metadata (for example indirect blocks, directory blocks) directly associated with user files plus the space reserved in the volume for these files (hole and overwrite reserves). This is the same information displayed by running the Unix du command on the mount point.

[-user-data-percent <percent_no_limit>] - User Data Percent

If this parameter is specified, the command displays information only about the volume or volumes that have the specified percentage of space in use by user data in the volume.

[-dedupe-metafiles {<integer>[KB|MB|GB|TB|PB]}] - Deduplication

If this parameter is specified, the command displays information only about the volume or volumes that have the specified amount of space in use by deduplication metafiles in the volume.

[-dedupe-metafiles-percent <percent>] - Deduplication Percent

If this parameter is specified, the command displays information only about the volume or volumes that have the specified percentage of space in use by deduplication metafiles in the volume.

[-dedupe-metafiles-temporary {<integer>[KB|MB|GB|TB|PB]}] - Temporary Deduplication

If this parameter is specified, the command displays information only about the volume or volumes that have the specified amount of space in use by temporary deduplication metafiles in the volume.

[-dedupe-metafiles-temporary-percent <percent>] - Temporary Deduplication Percent

If this parameter is specified, the command displays information only about the volume or volumes that have the specified percentage of space in use by temporary deduplication metafiles in the volume.

[-filesystem-metadata {<integer>[KB|MB|GB|TB|PB]}] - Filesystem Metadata

If this parameter is specified, the command displays information only about the volume or volumes that have the specified amount of space in use by file system metadata in the volume.

[-filesystem-metadata-percent <percent>] - Filesystem Metadata Percent

If this parameter is specified, the command displays information only about the volume or volumes that have the specified percentage of space in use by file system metadata in the volume.

[-snapmirror-metadata {<integer>[KB|MB|GB|TB|PB]}] - SnapMirror Metadata

If this parameter is specified, the command displays information only about the volume or volumes that have the specified amount of space in use by SnapMirror metafiles in the volume.

Between SnapMirror transfers, some metadata is maintained to support storage-efficient transfers. During transfers, some additional space is used temporarily. This space is used in all SnapMirror destination volumes.

[-snapmirror-metadata-percent <percent>] - SnapMirror Metadata Percent

If this parameter is specified, the command displays information only about the volume or volumes that have the specified percentage of space in use by SnapMirror metafiles inside the volume.

[-tape-backup-metadata {<integer>[KB|MB|GB|TB|PB]}] - Tape Backup Metadata

If this parameter is specified, the command displays information only about the volume or volumes that have the specified amount of space in use by tape backup metafiles in the volume.

[-tape-backup-metadata-percent <percent>] - Tape Backup Metadata Percent

If this parameter is specified, the command displays information only about the volume or volumes that have the specified percentage of space in use by tape backup metafiles in the volume.

[-quota-metafiles {<integer>[KB|MB|GB|TB|PB]}] - Quota Metadata

If this parameter is specified, the command displays information only about the volume or volumes that have the specified amount of space in use by quota metafiles.

[-quota-metafiles-percent <percent>] - Quota Metadata Percent

If this parameter is specified, the command displays information only about the volume or volumes that have the specified percentage of space in use by quota metafiles.

[-inodes {<integer>[KB|MB|GB|TB|PB]}] - Inodes

If this parameter is specified, the command displays information only about the volume or volumes that have the specified amount of space in use by the inode metafile in the volume.

This is the amount of space required to store inodes in the file system and is proportional to the maximum number of files ever created in the volume. The inode file is not compacted or truncated, so if a large number of files are created and then deleted, the inode file does not shrink.

[-inodes-percent <percent>] - Inodes Percent

If this parameter is specified, the command displays information only about the volume or volumes that have the specified percentage of space in use by the inode metafile in the volume.

[-inodes-upgrade {<integer>[KB|MB|GB|TB|PB]}] - Inodes Upgrade

If this parameter is specified, the command displays information only about the volume or volumes that have the specified amount of space in use by the inode subsystem for the purpose of upgrading.

This is the amount of space required to store upgrading inodes in the file system and is proportional to the size of the inode metafile. Once the upgrade is complete, the space used by 'inodes' will be replaced with the space used for upgrade.

[-inodes-upgrade-percent <percent>] - Inodes Upgrade Percent

If this parameter is specified, the command displays information only about the volume or volumes that have the specified percentage of space in use for upgrading the inode metafile in the volume.

[-snapshot-reserve {<integer>[KB|MB|GB|TB|PB]}] - Snapshot Reserve

If this parameter is specified, the command displays information only about the volume or volumes that have the specified amount of space in use by the Snapshot reserve in the volume.

[-snapshot-reserve-percent <percent>] - Snapshot Reserve Percent

If this parameter is specified, the command displays information only about the volume or volumes that have the specified percentage of space in use by the Snapshot reserve in the volume.

[-snapshot-reserve-unusable {<integer>[KB|MB|GB|TB|PB]}] - Snapshot Reserve Unusable

If this parameter is specified, the command displays information only about the volume or volumes that have the specified amount of space reserved but unusable in the volume.

Snapshot reserve can be diminished under certain conditions to accomodate volume metadata. Creating space in the volume will make this space available.

[-snapshot-reserve-unusable-percent <integer>] - Snapshot Reserve Unusable Percent

If this parameter is specified, the command displays information only about the volume or volumes that have the specified percentage of space reserved but unusable.

[-snapshot-spill {<integer>[KB|MB|GB|TB|PB]}] - Snapshot Spill

If this parameter is specified, the command displays information only about the volume or volumes that have the specified amount of space in use by their Snapshot spill.

If Snapshot used space exceeds the Snapshot reserve it is considered to spill out of the reserve. This space cannot be used by the active file system until Snapshots are deleted.

[-snapshot-spill-percent <percent>] - Snapshot Spill Percent

If this parameter is specified, the command displays information only about the volume or volumes that have the specified percentage of space in use by the Snapshot spill.

[-performance-metadata {<integer>[KB|MB|GB|TB|PB]}] - Performance Metadata

If this parameter is specified, the command displays information only about the volume or volumes that have the specified amount of space in use for performance optimization in the volume.

[-performance-metadata-percent <percent>] - Performance Metadata Percent

If this parameter is specified, the command displays information only about the volume or volumes that have the specified percentage of space in use for performance optimization in the volume.

[-total-used {<integer>[KB|MB|GB|TB|PB]}] - Total Used

If this parameter is specified, the command displays information only about the volume or volumes that have the specified amount of space in use by the volume, including the space used by the Snapshot reserve.

This is equivalent to the used field in the output of the volume show command.

[-total-used-percent <percent_no_limit>] - Total Used Percent

If this parameter is specified, the command displays information only about the volume or volumes that have the specified percentage of space in use by the volume, including the space used by the Snapshot reserve.

[-physical-used {<integer>[KB|MB|GB|TB|PB]}] - Total Physical Used Size

If this parameter is specified, the command displays information only about the volume or volumes that have the specified amount of physical space in use by the volume.

This differs from total-used space by the space that is reserved for future writes. The value includes blocks in use by Snapshot copies.

[-physical-used-percent <percent_no_limit>] - Physical Used Percentage

If this parameter is specified, the command displays information only about the volume or volumes that have the specified percentage of physical space in use in the volume based on volume size including the space reserved for Snapshot copies.

[-logical-used {<integer>[KB|MB|GB|TB|PB]}] - Logical Used Size

If this parameter is specified, the command displays information only about the volume or volumes that have the specified amount of logical space in use by the volume. This includes space saved by all the storage efficiency features along with physical used space. This does not include Snapshot reserve but does consider Snapshot spill.

[-logical-used-percent <percent_no_limit>] - Logical Used Percent

If this parameter is specified, the command displays information only about the volume or volumes that have the specified percentage of logical space used in the volume.

[-logical-available {<integer>[KB|MB|GB|TB|PB]}] - Logical Available

If this parameter is specified, the command displays information only about the volume or volumes that have the specified amount of logical available space in the volume.
