Hmm, yes, what was I thinking....
But if I want to use LVM snapshots underneath glusterfs volumes (on
different bricks) who are then unified or afr'd, won't there be a
problem because the snapshots aren't taken at exactly the same time? Or
what would be the expected behavior if I for example roll back one
volume in an afr setup and not the other?

Hi Onyx,
GlusterFS volumes are file based. LVM requires block based
store. You cannot have LVM over GlusterFS. I am assuming
you are asking about GlusterFS over LVM. You can use LVM and
its snapshotting ability underneath the GlusterFS posix volume.
It will work transparently.

Has anyone ever tested LVM on top of a glusterfs volume? Would this
even be possible?
I'm interested because of the snapshot feature of LVM.
Thanks!
