I have Server 2012 with one storage pool and one virtual disk. The virtual disk uses layout parity and thin provisioning. It contained 4 physical disks. One of the physical disks failed. It was pulled and larger replacement disk was added.
The server manager now lists the failed drive as "Retired". Every attempt to remove the disk results in:
Error removing physical disk: There was an error removing {179f49b7-7657-11e2-93ea-806e6f6e6963} (fileserver). One of the physical disks specified could not be removed because it is still in use.
If I check the properties of the virtual disk, it states under health: "Physical disks in use", and lists the retired drive as "Lost Communication".
The physical drives have lots of free space, and the new drive has been added to the storage pool (but not the virtual disk). The "repair virtual disk" option is grayed out.
It seems I cannot attach the virtual disk until I remove the retired drive.
How can a disk that's sitting unplugged in another room be "in use"? How do I remove the retired drive?
