On a machine running Windows Server 2012 R2, I have a virtual disk consisting of 8 physical disks in a RAID-5 configuration. One drive died, so I replaced the dead drive and followed these instructions for repairing the virtual disk: Replacing a Failed Disk in Windows Server 2012 R2 Storage Spaces with PowerShell.

Everything seemed to be working great, with one discrepancy: despite completing the whole repair process with no errors, the virtual disk still is marked as "degraded", even though it once again has 8 healthy drives. What gives?

The file system on the virtual drive (which is backed up) is still accessible, but I'd like to know if I again have resiliency against a drive failure or not, but I can't find any information about why the virtual disk is still degraded, or how to determine if it really is degraded, or how to fix it.

Here is some powershell output that I hope will be useful. Thank you!

PS C:\Users\Administrator>

In case it matters, PhysicalDisk4 is the new replacement disk that I added to replace the dead disk.

Note that I'm cross-posting this from superuser after waiting a while for answers. Not sure if that's against protocol around here - I'll delete the other post if that's the done thing.
