Hi,
I am trying to figure it out the best way to add a disk/partition to an
existing LVM pool. A google search led me to this link (a thread from
this same mailing list, September 2013):

The interesting part is this:

I looked around but could not find any info on how to expand a libvirt

I'd like to verify that this is the proper way to grow the storage in a
libvirt LVM storage pool.
It's not the proper way in principle, but since libvirt doesn't
supportto extendthe volume groups for a logical pool yet, it's the only
way now. Onehint though,you can try to refresh the pool by command
"virsh pool-refresh" afterthe volume
group of the pool is extended. I.e, don't have to restart the pool."
I've tried this method and it works, but checking the pool XML using
"virsh pool-edit <vg_name>" shows that the XML didn't change. Is it
intended?
The versions I'm using:
# libvirtd --version
libvirtd (libvirt) 1.1.3
# virsh --version
1.1.3
Any thoughts/comments are welcome.
Thanks!
