I have a two node win2008 failover cluster, attached to SAN, and for two weeks ago I disovered that the Cluster Validation doesnt pass anymore. It stops on one of the shared disks (LUNs) and the error is "Failed to offline cluster disk 0 from node servername.domain, failure reason: More data is available." ??
It is only the Validation test that fails, it is no problem to move the resource from one node to the other
I have read the "ValidateStorage.log" and the only error I can find is
"CprepDiskOnline: Failed to get volume name for device
\\?\GLOBALROOT\Device\Harddisk4\Partition1\, status 3"
but I get that for all the for all "Harddisks" even on disks where the test is ok?
I have run chkdsk without any errors
Is the failover test the problem or?
Appreciate all help I can get
