expand volume

Description Expands a standard volume. Expansion is restricted to the space available in the vdisk containing

the volume.

Volume sizes are aligned to 4-MB boundaries. When a volume is created or expanded, if the

resulting size would be less than 4 MB it will be increased to 4 MB; if the resulting size would be

greater than 4 MB it will be decreased to the nearest 4-MB boundary.

If insufficient space is available for expansion on the vdisk, first expand the vdisk by using expand

vdisk.

To expand a master volume:

1. Delete all of its snapshots by using delete all-snapshots.

2. Convert it to a standard volume by using convert master-to-std.

3. Expand the standard volume by using expand volume.

4. Convert the expanded volume to a master volume by using convert std-to-master.

Syntax To expand by a specific size:

expand volume

size

[B|KB|MB|GB|TB|KiB|MiB|GiB|TiB]

volume

To expand to the maximum size:

expand volume

size max

volume

Parameters size

size

[B|KB|MB|GB|TB|KiB|MiB|GiB|TiB]

Specifies the size using the current base, as shown by the show cli-parameters command. The unit

can be specified as follows:

• If base 2 is in use: B (bytes), KiB (kibibytes), MiB (mebibytes), or GiB (gibibytes)

• If base 10 is in use: B (bytes), KB (kilobytes), MB (megabytes), or GB (gigabytes)

If no unit is specified, the unit is 512-byte blocks.

size max

Expands the volume to fill the available space on the vdisk.

volume

The name or serial number of the volume to expand. For volume syntax, see "Command syntax"

(page 20).

Example Expand standard volume V1 by 100 GB:

# expand volume size 100GB V1

Success: Command completed successfully. - Expansion of volume V1 was

successful. (2012-09-19 10:16:05)
