I have a 6 node Hyper-V 2012R2 cluster managed by VMM 2012R2 using two CSVs
for testing I have completed a couple of storage migrations of running VMs from CSV1 to CSV2.
VMM says it is all ok and completed successfully, it even shows the VM as still running.
Failover clustering shows the VM failed with even 1069 error code '0x2' "The system cannot find the file specified"
Best of all Hyper-V Manager doesnt show the VM on any of the hosts!
failover clustering then moves the VM about onto different hosts to bring it back online but this fails.
looking at the old files on CSV1 I can see there is a .BIN file left in "C:\ClusterStorage\CSV1\test3\Virtual Machines"
This file has copied to "C:\ClusterStorage\CSV2\test3\Virtual Machines"
I cannot delete the old file from the CSV1 location.
I have checked AV exceptions and they arent scanning CSV1
I have also used process explorer to see if I could see what had a lock on the BIN file but the only things I found were explorer.exe and vmms.exe on the host that was hosting the VM originally.
I have resolved this previously by rebooting all hosts in the cluster but that is not really a long term solution as the VM is offline
any suggestions?
