Ok, I've got the plan: 1. unmount volume on all clients 2. shut down glusterd on all nodes 3. set old op.version (310xx) via /var/lib/glusterd/glusterd.info on all nodes 4. downgrade rpm packages everywhere 5. start glusterd & mount volume
Does it look fine? Also is there any way to roll back without downtime?
