Delete a Physical Volume

You can delete a physical volume using the system-host-pv-delete command.

  • You must lock a host before you can modify its settings.

    ~(keystone_admin)$ system host-lock <hostname>

  • A suitable local volume group must exist on the host. For more information, see Work with Physical Volumes <work-with-physical-volumes>.

  • An unused disk or partition must be available on the host. For more information about partitions, see Work with Disk Partitions <work-with-disk-partitions>.

The syntax of the command is:

system host-pv-delete <hostname> <uuid>

where:

<hostname>

is the name or ID of the host.

<uuid>

is the uuid of the physical volume.

For example, to delete a physical volume from compute-1, use the following command.

~(keystone_admin)$ system host-pv-delete compute-1 9f93c549-e26c-4d4c-af71-fb84e3fcae63
