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 managed LVM storage pool.  I do not see any virsh command to do it

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 support to extend the volume groups for a logical pool yet, it's the only way now. One hint though, you can try to refresh the pool by command "virsh pool-refresh" after the 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!
