Hi All,
We have a active/passive Windows 2008 R2 cluster, and I installed a SQL 2008 R2 instance on the cluster, Quorum configuration is node and disk majority. Now we had an issue when we did failover. I failed over MSDTC and SQL instance from N1 to N2, moved quorum from N1 to N2, but when I rebooted the new passive node N1, all disks on active node N2 lost at the same time, then they were back ~30 seconds later, I test a couple of times, could not find the reason. We have other clusters which have the same installation/setup, they had no problem at all. Could anybody give me a hand to sort the issue? I will post the related event log and cluster log.
Thank you very much.
David
