How to fix resiliency in a Storage Space.

Question

Hello there.

I've been trawling the internets for solutions to my problem but come up blank so I'm trying here.

I have a storage pool with two drives, running on Windows 10 Pro.
In there, i have a storage space, with two-way mirror resiliency.
The other day, one of the drives got unplugged. After getting it back online, the storage space reports reduced resiliency.

Here's what powershell has to say:

---

What's more, there is a suspended repair job going, since boot, that does nothing:

---

PS C:\WINDOWS\system32> Get-StorageJob

Name IsBackgroundTask ElapsedTime JobState PercentComplete BytesProcessed BytesTotal

---

Storage space-Repair True 02:51:49 Suspended 0 0 B 6.5 GB

---

So: How do I get my virtual disk to self-heal? After all, it was using two-way mirroring, and so all the data is there. Why cannot it bring both disks back into sync?
How can I un-suspend the automatic storage repair job? Why is it even suspended in the first place?

Btw, there are no errors in the event logs for microsoft->Microsoft windows ->StorageSpaced-drover since reboot. I've done several reboots.

Any suggestions greatly appreciated.

Hi，

How do we remove the disk perviously? Have we retired the disk first before removing it?
