We are using a 6 node DELL R740xd. The cluster passed the cluster validation test.
the node's did not reboot but the Cluster Shared Volume was off line and came only back to live after a 22! hour check...
after the CSV was back online we found all VM's were being moved onto one host.
after examining the logfiles it looked like the cluster service removed the owner node off the CSV from the cluster instead of deactivating the disk, or the node containing the faulty disk.
any suggestions as to why this is possible.
