Hi all, we are currently implementing an informix dbms cluster using Linux-HA (1.2.3) and drbd (0.7.5) on SLES9 SP2. Everything is working perfectly well so far, thanks a lot for all the work that has been done. I have a question about a special situation that may be an FAQ but still I didnt find any answers yet: 1. NodeA (P) --- NodeB (S) # everything ok 2. NodeA (P) - - NodeB (S) # DRBD detects connection loss, goes WFC 3. NodeA (P) - - NodeB (S) # Linux-HA detects split brain, A kills B 4. / - - NodeB (P) # NodeB takes over, goes primary There have been writes on NodeA between step 2 and 3. These are lost after Linux-HA has killed A and made B primary. I know the best solution is to avoid this situation by any chance and we are using serial heartbeats, too, but what if it happens anyway? Thanks for any help, Christof
