If you can’t go direct, how about round about, with an iSCSI gateway.

I have for many years used gluster because..well. 3 nodes.. and so long as I 
can pull a drive out.. I can get my data.. and with three copies.. I have much 
higher chance of getting it. 





Downsides to gluster: Slower (its my home..meh... and I have SSD to avoid MTBF 
issues ) and with VDO.. and thin provisioning.. not had issue. 





BUT.... gluster seems to be falling out of favor. Especially as I move towards 
OCP. 





So.. CEPH. I have one SSD in each of the three servers. so I have some space to 
play. 





I googled around.. and find no clean deployment notes and guides on CEPH + 
oVirt. 





Comments or ideas..
