I am upgrading a two node cluster to Windows 2012 Preview. I had problems with hardware it seems on the first node but got it going after a bit, but the second node upgraded in-place without problems. I only had to recreate the NIC team and recreate the switch with PowerShell. No problem.
I did run into some difficulty. Here is a brief description:
To get the initial node up and running so as to migrate all the roles, I created an AD Detached Cluster and joined the upgraded host to that cluster. This allowed me to copy over all the roles from the original cluster to this new one and I used the -nostorage option, which worked well. Then I had to destroy the original cluster and upgrade the remaining host to R2 to match the first one (also went well). Problem is when all was done it seems that one volume (Volume1) on my shared storage (HP P2000) is unable to be added to the Cluster Shared Volumes. "Volume2" and the Quorum disk did add just fine, but the System Volume (where all my C: drive VHD's Lived) "Volume1" is visible, I can put it offline or online but when I try to Add it with Failover Cluster Manager, I get the message that "No suitable disks for Cluster Disks could be found." I have tried everything, it seems like something got corrupted on it. I have exported the VM's to the second volume so I have a copy, but it really would be nice to know what happened as I am trying to nail down a procedure for future rolling upgrades. Any advice would be appreciated!
