I had a Windows 2012 R2 hyper-v core installed on a disk that crashed. I had set up a storage pool with 4 disks in it.
I replaced the crashed disk and reinstalled the OS, but the storage pool is gone.
If I run get-storagepool
all I get is
FriendlyName OperationalStatus HealthStatus IsPrimordial IsReadOnly
------------ ----------------- ------------ ------------ ----------
Primordial OK Healthy True False
And if i run get-physicaldisk
i get the following
FriendlyName CanPool OperationalStatus HealthStatus Usage Size
------------ ------- ----------------- ------------ ----- ----
PhysicalDisk3 False Unrecognized Met... Unhealthy Unknown 4.55 TB
PhysicalDisk0 False Unrecognized Met... Unhealthy Unknown 3.64 TB
PhysicalDisk1 False Unrecognized Met... Unhealthy Unknown 2.73 TB
PhysicalDisk4 False OK Healthy Auto-Select 55.9 GB
PhysicalDisk2 False Unrecognized Met... Unhealthy Unknown 2.73 TB
PhysicalDisk4 is the OS disk!
Edit: Well i think i know what happend now, when the disk went offline i used a USB stick with the windows 10 installation media to get access to CMD just to check the status of things, i guess it then upgraded the storage pool to a windows 10 storage pool, and 2012 R2 can't read that. i have no idea if i can downgrade it somehow?
