[Kimchi-devel] RFC: "Add disk to existing logical storage pool"

[Aline Manera]

Hi Daniel,

Did you try to edit the pool xml and add a new device for it? Instead of 
doing it manually though vgextend command

For example:

virsh pool-destroy lvm-pool

virsh pool-edit lvm-pool
(add a new device for it)

virsh pool-start lvm-pool

I don't know if it is possible but we give it a try

Regards,
Aline Manera
