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 :
https://access.redhat.com/documentation/en-US/Red_Hat_Storage/3/html/Administration_Guide/Formatting_and_Mounting_Bricks.html
http://gluster.readthedocs.io/en/latest/Administrator%20Guide/Setting%20Up%20Volumes/

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! :)

Quentin
