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.
