Display a list of volume capacity rebalancing operations on FlexGroup volumes

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

Description

The volume rebalance show command displays information about volume capacity rebalancing operations on FlexGroup volumes.

The volume rebalance show command is only supported on FlexGroup volumes and constituents. The command displays rebalancing information for volumes. 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:

  • Vserver name

  • Volume name

  • Rebalancing state

  • Total size

  • Used size for calculating imbalance

  • Size used by Snapshot copies

  • Target used size

  • Imbalance size

  • Imbalance percent

To display detailed rebalancing information about each FlexGroup volume or constituent, run the command with the -instance parameter. The detailed view provides the following information for FlexGroup volumes:

  • Vserver name

  • Volume name

  • Is constituent

  • Rebalance state

  • Total size

  • Used size for calculating imbalance

  • Size used by Snapshot copies

  • Imbalance size

  • Imbalance percentage

  • Maximum constituent imbalance percentage

  • Rebalance start time

  • Rebalance stop time

  • Rebalance runtime

  • Rebalance maximum runtime

  • Maximum imbalance threshold per constituent

  • Minimum imbalance threshold per constituent

  • Maximum files moved per constituent

  • Minimum file size

  • Exclude files stuck in snapshot copies

  • Rebalance notice messages

The detailed view provides the following information for FlexGroup constituents:

  • Vserver name

  • Volume name

  • Is constituent

  • Rebalance state

  • Total size

  • Used size for calculating imbalance

  • Size used by Snapshot copies

  • Constituent target used size

  • Imbalance size

  • Imbalance percentage

  • Moved data size

  • Rebalance start time

  • Rebalance stop time

  • Rebalance runtime

  • Rebalance maximum runtime

  • Rebalance maximum runtime

  • Maximum imbalance threshold per constituent

  • Minimum imbalance threshold per constituent

  • Maximum files moved per constituent

  • Minimum file size

  • Exclude files stuck in snapshot copies

You can specify parameters from the above list to display information. For example, to display information only about currently running rebalancing operations, run the command with the -state rebalancing parameter

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.

| [-config ]

If this parameter is specified, the command displays the following information:

  • max-runtime

  • max-threshold

  • min-threshold

  • max-file-moves

  • min-file-size

  • exclude-snapshots

| [-time ]

If this parameter is specified, the command displays the following information:

  • start-time

  • runtime

  • max-runtime

| [-instance ] }

If this parameter is specified, the command displays the additional detailed information described above.

[-vserver <vserver name>] - Vserver Name

Selects information about volume capacity rebalancing operations on FlexGroup volumes in the specified Vserver.

[-volume <volume name>] - Volume Name

Selects information about volume capacity rebalancing operations on the specified FlexGroup volume.

[-is-constituent {true|false}] - Is Constituent

If specified, the command displays information about volume capacity rebalancing operations on constituents.

[-state {idle|starting|rebalancing|rebalancing-source|rebalancing-dest|scanning|stopping|paused|not-running|unknown}] - Rebalance State

Selects information about volume capacity rebalancing operations with the specified state. While a FlexGroup volume is rebalancing, every constituent will have a rebalancing engine that can either be scanning the filesystem for space usage and files to move, actively moving files or temporarily doing neither. If one or more constituents has a state of rebalancing-source or rebalancing-dest , then files are being moved to rebalance the FlexGroup. If no files are being moved, more information about what the rebalancing engine is doing for each constituent is available using the (privilege: advanced) volume rebalance show -instance command. The following values apply to FlexGroup volumes.

  • not-running - Capacity rebalancing is not running on the volume. This will only change when the user explicitly starts rebalancing.

  • idle - Capacity rebalancing is running, however, no active scanning or file movement is currently happening.

  • starting - The capacity rebalancing operation is starting on the volume.

  • rebalancing - Volume capacity rebalancing is running on the volume.

  • paused - The capacity rebalancing operation is paused on the volume.

  • stopping - The capacity rebalancing operation is stopping on the volume.

  • unknown - The system was unable to determine the rebalancing state for the volume.

[-notices <text>,…​] - Rebalance Notice Messages

Selects information about volume capacity rebalancing operations with the specified notice messages.

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

Selects information about volume capacity rebalancing operations with the specified total size.

[-used-for-imbalance {<integer>[KB|MB|GB|TB|PB]}] - Used Size for Calculating Imbalance

Selects information about volume capacity rebalancing operations with the specified used size for calculating imbalance. This is calculated by subtracting the size used by Snapshot copies, the size of files pending deletion and the size used by filesystem metadata from the volume's used size.

[-size-used-by-snapshots {<integer>[KB|MB|GB|TB|PB]}] - Volume Size Used by Snapshot Copies

Selects information about volume capacity rebalancing operations with the specified volume size used by Snapshot copies.

[-target-used {<integer>[KB|MB|GB|TB|PB]}] - Constituent Target Used Size

Selects information about volume capacity rebalancing operations with the specified target used size on a constituent. Represents the average used size among all constituents.

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

Selects information about volume capacity rebalancing operations with the specified imbalance size.

[-imbalance-percent <percent_no_limit_signed>] - Imbalance Percentage

Selects information about volume capacity rebalancing operations with the specified imbalance percentage.

[-data-moved {<integer>[KB|MB|GB|TB|PB]}] - Moved Data Size

Selects information about volume capacity rebalancing operations with the specified moved data size.

[-max-constituent-imbalance-percent <percent_no_limit>] - Maximum Constituent Imbalance Percentage

Selects information about volume capacity rebalancing operations with the specified maximum constituent imbalance percentage. Represents the imbalance percentage of the constituent most out of balance.

[-start-time <Date>] - Rebalance Start Time

[-max-runtime <time_interval>] - Rebalance Maximum Runtime

Selects information about volume capacity rebalancing operations with the specified maximum run time. Represents the maximum amount of time a rebalancing operation can run for before stopping.

[-max-threshold <percent>] - Maximum Imbalance Threshold per Constituent

Selects information about volume capacity rebalancing operations with the specified maximum threshold. Represents the acceptable imbalance threshold beyond which rebalancing should be started on that constituent in the FlexGroup volume.

[-min-threshold <percent>] - Minimum Imbalance Threshold per Constituent

Selects information about volume capacity rebalancing operations with the specified minimum threshold. Represents the minimum imbalance threshold at which rebalancing is stopped for the constituent in the FlexGroup volume.

[-max-file-moves <integer>] - Maximum Concurrent File Moves per Constituent

Selects information about volume capacity rebalancing operations with the specified maximum concurrent file moves. Represents the maximum number of concurrent file moves allowed per constituent.

[-min-file-size {<integer>[KB|MB|GB|TB|PB]}] - Minimum File Size

Selects information about volume capacity rebalancing operations with the specified minimum file size. Represents the minimum size of file to be considered for rebalancing a constituent in a FlexGroup volume.

[-exclude-snapshots {true|false}] - Exclude Files Stuck in Snapshot Copies

Selects information about volume capacity rebalancing operations with the specified excluding snapshot flag. Represents whether or not files that are in Snapshot copies as candidates for rebalancing are ignored.
