So I made the ‘mistake’ of destroying a Microsoft Failover Cluster and thinking Windows would release my disks. Well I was wrong!
I went to Disk Manager and saw my disks as ‘Online’, ‘Primary’ and ‘RAW‘.
And off course I could not access the disks from the Explorer, giving me a nice Error.
OK to Disk Manager and wipe the disk.
But wait, in USE??
So there must have gone something wrong.
Technet search gave me this: http://technet.microsoft.com/en-us/library/ee461016.aspx
There is a command for releasing the disks that need releasing after a Cluster destroy, or even an ungraceful shutdown!
Powershell and give in:
Clear-ClusterDiskReservation –Disk <DiskNumber>
A Refresh of Disk Manager showed my disk again and it became visible in Explorer, yeah!
