Cluster Disk stuck in "Online Pending"

Question

Saturday, February 8, 2014 10:02 PM

I am currently seeing this under my Storage in the Failover Cluster Manager on Server 2012 r2....
"Cluster Disk 2" is stuck in an "Online Pending" state. The thing is I don't have any disk that would be claiming this role.

When I try and look at the properties of this disk I get a message: "operation has failed..... unable to cast object of type 'MS.Internal.ServerClusters.Cluster' to type 'MS.Internal.ServerClusters.ClusterResource'. " or sometime the MMC crashes with an unhandled exception. If I try and remove it in the Failover Cluster MMC, it fails with "The file cannot be opened because it is in the process of being deleted. Error Code: 0x8007012f "

If I try and remove it with cmdlets in PowerShell, ' Remove-ClusterResource "Cluster Disk 2", no result because the resource doesn't exist. 'Get-ClusterResource' shows no resource related to the ghost disk.

Any thoughts on what may be causing this ghost disk to be showing up as available storage, or any resolutions to removing it.

Hi,

Did you Reboot the Cluster nodes ? I have seen cases when adding the new disk results in the same problem.

I ended up draining the node that "owned" the disk. Everything but the additional storage drained off nicely, as it just sat there waiting and waiting to drain. I ended up just restarting the node, which forced it to another node in an offline state. From there I was able to remove it. Still not sure how it got there. But its gone now.

And the validation tests when configuring the cluster yielded no warnings/errors.

Did you run the cluster validation wizard on the configuration before you built the cluster?  Any warnings/errors in its output?

Hi,

Please rerun the validation test then post the error part, that will quickly location the issue.

Thanks.
