I've done it a lot between glusterfs and other storages (local, nfs, other gfs ..),
works fine. No dataloss, no inconsistency.
The only problem I have is the vm crashes when it reaches 100% almost everytime,
it gets restarted by HA quickly but that's still annoying. It's been happening
for years on all our clusters, but for some reason no one else has that problem,
so I assume it's something to do with the glusterfs implementation or something.
