Hi everyone! I'm setting up a little cluster with two identical machines running CentOS 5.2 and drbd 8.2.6. drbd is mirroring a logical volume that contains a Xen 3.2.1 domU, which is running a Samba server. The domU's configuration uses drbd directly (disk=[drbd:samba-disk,xvda1,w]), so Xen handles drbd state. Right now I'm testing failover/failback *without heartbeat* (for simplicity of testing) and I can't figure how a way to handle failback :( My test goes like the following: Initially drbd is in Connected Secondary/Secondary mode -> Start the VM on node1 drbd on node1: Connected Primary/Secondary -> Unplug network cables from node1 to simulate a failure drbd on node2: WFConnection Secondary/Unknown -> Start the VM on node2 to simulate failover drbd on node2: WFConnection Primary/Unknown -> Copy a file via Samba -> Reconnect node1 drbd on node1: WFConnection Primary/Unknown drbd on node2: StandAlone Primary/Unknown What should I do now to reconnect drbd so that I don't lose the file I copied via Samba? I think I should stop the VM on node2, reconnect drbd (which I don't know how) and restart the VM on node1, am I right? Many thanks for your time! (Sorry if this isn't the right ML for my question: as there are so many interconnected technologies in play, it's a bit tricky to figure out each one's responsibility ^^; )
