I am running Windows Server 2012 Essentials and I have an identical pair of Western Digital 6 TB (Red NAS) drives in a two-way mirror storage space (assigned to drive S:).
Yesterday this storage space was at about 60% full. Today I was copying a file to the storage space when I suddenly got a message stating that the location was not available.
When I immediately logged on to the server, I found that the S: drive was gone. I rebooted the server and now when I look at "Storage Spaces" through control panel the storage pool shows "Error - No capacity; add 2 drives" and "Using 10.9 TB of 10.9 TB pool capacity." (10.9 TB is the combined capacity of the two 6 TB [actually 5.45 TB] drives). The storage space and the files on it are accessible but I cannot save anything new to it.
When I check the properties of ALL the files in the storage pool, Windows reports about 3.4 TB of data stored. The "Physical Drives" section reports both drives as Okay.
How did it suddenly get filled and how do I fix it?
Any help or suggestions would be greatly appreciated.
Thanks.
Allan
