Windows 10: Windows Storage Spaces: replacing dead drive in two-way mirror gets stuck

I previously had set up a two-way mirror with Windows Storage Spaces across two physical HDDs of the same size to protect against a single drive failure. The other day, after a power failure, I found one of the drives had apparently completely died. It didn't appear in Disk Management and running Get-PhysicalDisk in PowerShell showed "Lost Communication" for that drive. My data in the Storage Spaces virtual drive was still accessible. Okay, no problem, I thought -- this is exactly what I set up the mirror for.

I ordered a new drive of the same size, disconnected the old one, and installed the new one in its place. I opened the Storage Spaces control panel, added the new drive to the pool, and clicked "Remove" on the dead one. Then its status showed "Preparing for removal," and the % used figure started to dwindle. Running Get-StorageJob showed two jobs running "Storage space-Repair" and "Storage space-Regeneration", both with a BytesTotal value of about the amount of data I had, and percent complete ticking steadily upward.

Now, after several hours, this process seemed to have completed. But the old drive still appears in Storage Spaces as "Preparing for removal," with 0.06% used. When I run Get-StorageJob, I still see the "Storage space-Repair" job; occasionally another "Storage space-Regeneration" job appears briefly see below. The status in the control panel alternates between "Warning: Low capacity; add 2 drives" when there is a "Storage space-Regeneration" job running and "Error: No resiliency" when there isn't.

What's going on? Why does it seem to be stuck? I thought this would be a straightforward process.

Example of Get-StorageJob output usually the first; occasionally, briefly, the second.

Storage spaces retired disk in mirror - drive seems ok


Hi all - have set up a mirror configuration in storage spaces of 2 4TB drives. I have got a waning that there is a problem and in the storage spaces GUI it shows as one drive been retired (a seagate ST4000DM000) and need replacing. I run a short test of the drive with SeaTools and it passed the test fine so I wonder what I should do and how: Is there a way to un-retire a disk and try it again? is my only option to buy a new disk? if I buy a disk do I need to unplug all the drives in the meantime for fear of corrupted data because the mirror is not working? when the drive is retired is it still used by storage spaces to mirror the data?
any advice will be welcomed

 

Storage Spaces Mirror 2 Drives?

Actually... no. If you plug out a mirror from a Storage Spaces mirror and plug into another Windows 10 machine, it will first warn you that a Storage Space is in trouble, but seconds later your plugged mirror is fully available. I just tried.
Interesting enough, you can keep working and modifying your now "reduced resiliency" space. When you plug the missing drive back to your real Storage Spaces machine it gets in sync and back to normal.

I came here looking for some more experienced users having tried this before, but I see that it's a bit crazy and no one has tried it. So far, I'm starting to believe this is a great way to have an always updated roaming media storage.
I wonder what would happen if the roaming media gets modified, it would be overwritten once back in the mirror?

 

Simple Storage Space to Two-Way MIrroring possible?

I currently have a 4 drives setup as a Simple storage space. I recently got 4 more drives and I was wondering if I could enable two-way mirroring without having to reformat everything?
