Increase the Size of a PartitionΒΆ
You can increase the size of a partition using the system host-disk-partition-modify command.
About this task
You can modify only the last partition on a disk (indicated by part in the device path; for example, /dev/disk/by-path/pci-0000:00:0d.0-ata-2.0-part6).
You cannot decrease the size of a partition.
The syntax for the command is:
system host-disk-partition-modify -s <size> <host> <partition>
where:
- <size>
is the new partition size in MiB.
- <host>
is the host name or ID.
- <partition>
is the partition device path or UUID.
For example, to change the size of a partition on compute-1 to 726 MiB, do the following:
~(keystone_admin)]$ system host-disk-partition-modify -s 726 compute-1 a259e898-6390-44ba-a750-e0cb1579d8e0 +-------------+--------------------------------------------------+ | Property | Value | +-------------+--------------------------------------------------+ | device_path | /dev/disk/by-path/pci-0000:00:0d.0-ata-2.0-part6 | | device_node | /dev/sdb6 | | type_guid | ba5eba11-0000-1111-2222-000000000001 | | type_name | LVM Physical Volume | | start_mib | 512 | | end_mib | 12545 | | size_mib | 726 | | uuid | a259e898-6390-44ba-a750-e0cb1579d8e0 | | ihost_uuid | 3b315241-d54f-499b-8566-a6ed7d2d6b39 | | idisk_uuid | fcd2f59d-c9ee-4423-9f57-e2c55d5b97dc | | ipv_uuid | None | | status | Modifying | | created_at | 2017-09-08T19:10:27.506768+00:00 | | updated_at | 2017-09-08T19:15:06.016996+00:00 | +-------------+--------------------------------------------------+
