Hi, bit of a strange one here...
I'm currently testing out a Hyper-V Failover Cluster on Windows Server 2012 Standard. We are using shared storage Synology RS810RP+ which supports LUN/iSCSI targets and is working just fine and giving no errors either as standalone disks or as witness disks on the cluster.
The problem is that when I add an available volume (reported as online available storage) to the cluster shared volumes, they come up, briefly report as Online, and then revert to a state of Online (No Access). They do not appear in C:\ClusterStorage on either of the cluster member nodes. There are no errors (or warnings, or even informational events) in the cluster event log or windows event logs, and I can find no way of resolving the issue.
To further confuse matters, if I put the disk into Maintenance Mode, it changes to Online (In Maintenance), successfully mounts itself on its owner node, and allows me to add files etc.
I can find no reference to the state Online (No Access) aqnywher in teh Googleverse, so if anyone knows what's going on, I;d be very grateful of pointers!
Thanks in advance,
