[Kimchi-devel] [PATCH v2 0/4] Add disks to LVM pool backend
From: Daniel Henrique Barboza <danielhb(a)linux.vnet.ibm.com>
Changes in v2:
- added API.json parameter verification
- added disk verification
- added mockmodel improvements
- other improvements based on feedback
This patch series implements the backend changes to allow disks/partitions to
be added to an existing LVM (logical) pool.
The process, as discussed previously in kimchi mailing list, is to use
'vgextend' and 'virsh pool-refresh' commands to add the disks and then
refresh the pool.
It is also worth noticing that the existing data from the disks/partitions
being added to the pool will be erased/lost.
To test the patch:
$ curl -u root -H 'Content-type: application/json' -H 'Accept:
application/json' -X PUT localhost:8000/storagepools/<pool_name> -d
'{"disks": ["/path/to/disk1", "/path/to/disk2"] }'
Tip: to test the patch over and over with the same pool and disks
without the need to destroy/create the pool:
$ vgreduce <pool_name> disk1 disk2
$ virsh pool-refresh <pool_name>
The above commands will restore the logical pool to its previous state,
before adding disks 'disk1' and 'disk2'
