Hello, That's a clear anwser :). Thank you for that. The core issue I'm trying to solve is the lack of HA indeed. And at some previous employer I saw Ceph in action and Ceph itself did what it promised. In the end it had way to little performance for what we were trying to do with it, but as a technology it rocked. So that's the reason I'm looking at Ceph now, for my own project. I don't need the performance now. I will look into DRBD and HAST (the FreeBSD version of DRBD) in a bit more detail, maybe that's the way to go. And when the DRBD/HAST cluster has become too small for what I use it for, I can always upgrade to Ceph at that point :).
