Hi we just recently upgraded from 7.3.2 to 8.0.3 on our FAS3140 cluster. As usual, all ESX/vmware hosts connected to NFS storage were absolutely fine during the 'cf takeover' and 'giveback' processes....as we all windows standalone iscsi connected hosts.
We have a couple of 2008R2 Hyper-V clusters now and utilize cluster shared volumes in both of them. These guys didn't do so well during the takeover/givebacks. They showed all available storage as offline (CSV, quorum disk, etc) and several if not all of the VMs on these clusters rebooted by themselves. Anyone else experience similar symptoms from HV clusters during (what is supposed to be) a non-disruptive upgrade? Anyone have any take on what makes the clusters sooo much more sensitive to that moment in time when all sessions are in limbo until takeover or giveback is complete?
