Hi! Things I've seen with SLES11 SP1 and a two-node cluster was this:
If only one node is alive, it takes quite some time (about 20 minutes) until the node becomed new domain controller. Ocassionally even if the second node comes up, both nodes cannot agree who's DC for quite some while. Nothing will happen unless there's a DC, and nothing will happen if the cluster has no quorum. Maybe check those. Reading syslog messages may help you to understand what's going on. I still don't understand all the stuff thst's happening, but after some time you learn what "just happens". BTW: Is there anybody there to explain all the "synapse" and "firing" stuff? Years ago I was quite good in neurophysiology, but I cannot relate it to cluster resources ;-) Regards, Ulrich >>> "Yount, William D" <[email protected]> schrieb am 02.08.2012 >>> um 10:43 in Nachricht <11893698c5a8c84ea0b5484deb54e375025a983...@dcxprcl018.cnf.prod.cnf.com>: > Attached is my cib.xml file. > > I have a two node DRBD cluster setup in Active/Active.
