As far as I know from official RHEV docs, the better reference page is this
(for RHEV 3.4):

https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualization/3.4/html/Administration_Guide/Understanding_virtual_disks.html

But I don't see in that table a clear statement for GlusterFS... is it like
NFS?

Also, in my opinion, it would be nice to add, in the first column field,
the word "(default)" for the corresponding line if feasible.
