Mac mini M1, 2020 running Sequoia 15.1, RAID 5
One of six harddrives failed recently in my ThunderBay enclosure. I ordered a new drive, removed the old one, verified it, initialized it, then tried to "Add Disk" in the Volume menu. The rebuilding process has been running for two days now, but I'm not sure it's going anywhere. The ThundayBay volume disk is vacillating between these two "waiting for mount" messages (see screenshots attached).
Any advise on how to troubleshoot or move things forward? Tech report attached.
Thanks!
Nick

Was it mounting before you used "Add disk"?

I'm not sure, I don't think I knew to look for this detail.
It was (and it is) showing up on the left column of Disks normally, like the other drives in the Thunderbay. Does that mean it is mounted? I don't see "mounted" or "unmounted" anywhere in the details.

Attach a SoftRAID tech support file and I can check. (Utilities menu)

I attached a tech support file to the initial post. Please let me know if you cannot access it, thanks!

Can you attach again? It did not get through. thanks. Could be on the Forum end.

Yes your volume is mounted.
It should be rebuilding, but I do not see the progess I would expect.
If you restart, run SoftRAID, do you see progress in the volume tile? (the counter incrementing for "offset"?)

@softraid-support I did as directed. The current offset went from 392,724,480 before rebooting to 2,101,493,760 after rebooting. So I suppose this means progress is happening, albeit slowly. Do you know what number the offset must reach to complete the rebuilding task? Anything I can do to speed the job along? Thanks!

Optimized for Server is the fastest rebuild. It will rebuild as fast as possible. Your volume is mounted and usable, you do not need to wait for the rebuild to complete to use your volume.

For some reason the volume won't work. I can look inside at the drive contents, but many of the file folders are empty.

The issue then is a damaged HFS directory. Disk Warrior is your friend here. Its highly likely to fix everything in place. Its commercial, but an excellent application for HFS volumes.
Sorry for this. But it explains the lack of progress.

I own Disk Warrior and just updated it to the current version. How should I proceed? Do I simply choose my ThunderBay volume and click "Rebuild"? Is it OK to run Disk Warrior while SoftRaid says the Volume is rebuilding?
Thanks for your guidance here!

I tried rebuilding the directory with Disk Warrior. First, I restarted my computer. Then, with SoftRaid closed, I started up Disk Warrior. I select the ThunderBay volume. After I click "Rebuild," however, nothing happens. Screenshot attached.

DiskWarrior directory rebuild finished... now SoftRaid rebuilding is going along much more quickly.
Unfortunately, DiskWarrior rebuild reported a massive number of problems, and key files are missing or corrupt. Not sure how to proceed.
All data is backed up via BackBlaze (cloud backup service). Should I request backup disks, format the entire ThunderBay volume, and restore the data via the external backup? It's beginning to feel complicated.
