Display a list of FlexClones

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

Description

The volume clone show command displays information about FlexClone clone volumes. This command is only supported for flexible volumes. By default, the command displays the following information about all FlexClone volume clones:

  • Vserver name

  • FlexClone volume name

  • Parent volume name

  • Parent snapshot name

  • Whether a FlexClone volume is online or offline

To display detailed information about all FlexClone volumes, run the command with the -instance parameter.

Parameters

{ [-fields <fieldname>,…​]

Selects the fields to be displayed.

| [-estimate ]

Displays an estimate of the free disk space required in the aggregate to split the indicated clone volume from its underlying parent volume. The value reported may differ from the space actually required to perform the split, especially if the clone volume is changing when the split is being performed.

| [-instance ] }

Displays detailed information about FlexClone volumes. If -flexclone is also specified, the command displays detailed information about the FlexClone volume.

Selects summary information for the FlexClone volumes on the specified Vserver. If -flexclone is also specified, the command displays detailed information about the specified FlexClone volume.

[-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 Flash Cache modules. If a caching policy is not assigned to this volume, the system uses the caching policy that is assigned to the containing Vserver. If a caching policy is not assigned to the containing Vserver, the system uses the default cluster-wide policy. 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.
