ahh, thanks, will check.

yes, i'm aware of that feature.

yes, but you do not only need HA for your storage appliance, you also
need to make the network or san in between highly available , too.
every storage update is something which makes you go very nervous...
ceph is too complex beast for us, we like simplicity.
