Re: [Gluster-devel] LVM

[Onyx]

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?
