mx dynvolume – dynamic volume commands

Use the following commands to create, recreate, extend, or destroy dynamic volumes, to display information about dynamic volumes, and to convert basic volumes to dynamic volumes.

Create a dynamic volume:

mx dynvolume create [--stripesize <4KB-64MB>]

<subDeviceName,subDeviceName,...>

List subdevices available for use in a dynamic volume:

mx dynvolume showcreateopt

Display properties for a dynamic volume:

mx dynvolume properties <volumeName>

Show all dynamic volumes:

mx dynvolume list

Extend a dynamic volume:

mx dynvolume extend <volumeName> <subDeviceName, subDeviceName,...>

Destroy a dynamic volume:

mx dynvolume destroy <volumeName>

A filesystem cannot be mounted on the volume that will be destroyed. This command also destroys any persistent mounts for the filesystem.

Convert a basic device to a dynamic volume:

mx dynvolume convert <filesystem>

Dump dynamic volume configuration to stdout:

mx dynvolume dump
