How to resolve virtual disk degraded in Windows Server 2012
- by harrydev
I am using the new Storage Spaces feature in Windows Server 2012. I have the following disks:
FriendlyName CanPool OperationalStatus HealthStatus Usage Size
------------ ------- ----------------- ------------ ----- ----
PhysicalDisk2 False OK Healthy Auto-Select 2.73 TB
PhysicalDisk3 False OK Healthy Auto-Select 2.73 TB
PhysicalDisk4 False OK Healthy Auto-Select 2.73 TB
PhysicalDisk5 False OK Healthy Auto-Select 2.73 TB
There is also a separate OS disk. The above disks are part of a single storage pool:
FriendlyName OperationalStatus HealthStatus IsPrimordial IsReadOnly
------------ ----------------- ------------ ------------ ----------
Pool OK Healthy False False
Within this storage pool some virtual disks are defined, see below:
FriendlyName ResiliencySettingNa OperationalStatus HealthStatus IsManualAttach Size
me
------------ ------------------- ----------------- ------------ -------------- ----
Docs Mirror OK Healthy False 500 GB
Data Mirror Degraded Warning False 500 GB
Work Mirror Degraded Warning False 2 TB
Now the virtual disks are all running normal 2-way mirror, but two of the virtual disks are degraded. This is probably because one of the physical disks was offline for a short period of time. However, now the virtual disk cannot be repaired, even though, all physical disks are healthy. There is plenty of available space in the storage pool.
This I cannot understand so I was hoping for some help, on how to resolve this?
Below I have listed the full output from the Get-VirtualDisk CmdLet for the "Work" disk:
