Hi everyone,
I've read on the gluster & redhat documentation, that it seems recommended to
use XFS over LVM before creating & using gluster volumes.
Sources :

My point is : do we really need LVM ?
For example , on a dedicated server with disks & partitions that will not
change of size, it doesn't seems necessary to use LVM.
I can't understand clearly wich partitioning strategy would be the best for
"static size" hard drives :
1 LVM+XFS partition = multiple gluster volumes
or 1 LVM+XFS partition = 1 gluster volume per LVM+XFS partition
or 1 XFS partition = multiple gluster volumes
or 1 XFS partition = 1 gluster volume per XFS partition
What do you use on your servers ?
Thanks for your help! :)

Hi Quentin,
Gluster relies on LVM for snapshots - you won't get those unless you deploy on LVM.
