Still, I would stick to gluster if you want a replicated storage: - It is supported out of the box and you get active support from lots of users here - Replica3 will solve most out of sync cases - I dare say other replicated storage backends do suffer from the same issues, this is by design. Two things you should keep in mind when running gluster in production: - Do not run compute and storage on the same hosts - Do not (yet) use Gluster as storage for Hosted Engine > I've been reading about GFS2 > and DRBD, and wanted opinions on if either is a good/bad idea, or to see if > there are other alternatives. > > My oVirt setup is currently 5 nodes and about 25 VMs, might double in size > eventually, but probably won't get much bigger than that. In the end, it is quite easy to migrate storage domains. If you are satisfied with your lab setup, put it in production and add storage later and move the disks. Afterwards, remove old storage domains. My to cent with gluster: It runs quite stable since some time now if you do not touch it. I never had issues when adding bricks, though removing and replacing them can be very tricky.
