[Kimchi-devel] [PATCH 0/3] Add disks to LVM pool backend

[Daniel Barboza]

From: Daniel Henrique Barboza <danielhb at linux.vnet.ibm.com>

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'
