To determine if this is the same RAID 5 panic, look at the panic log. If the top line has DART, then yes.

No your panics are different. I don't know the cause yet. It appears to be in the file system.

If it's not clear in the logs, it's a RAID 4 volume using APFS. Anything I can do to help troubleshoot?

Is there a lot of data on there? Can you backup/restore (erase the volume with SoftRAID).
This appears to be in the file system.

I've got ~8TB of 12TB filled so it's not impossible. The thing is I've had previous panics that were identified as being related to the file system by SoftRAID email support, and I've wiped/restored this at least a dozen times over the past few months, so I'm not sure formatting is really going to solve anything.
If I do erase it, should I do anything specific, or just format as APFS and copy my data back over? Or should I switch to HFS+ and give up on the flexibility of containers (I'm using spinning disks)?
Thanks,
Tony

I do not know why you are having these crashes, they do appear to be in the file system, but reading panic logs (by non programmers) is not definitive. You should be able to stick to APFS.
If I recall all you are really doing is finder copies, correct?

I'm using the Thunderbay on a Mac mini as a file server for the home. The Thunderbay hosts backup for several laptops (time machine and deja dup for some linux laptops), my old ripped music library, and as a Plex server. When I backup/restore to/from the Thunderbay (if I need to wipe for testing) I'm using using rsync.
I've also noticed that I have a disk that routinely goes 'missing' but returns after a reboot. I've confirmed it's always the same device (in slot A). I've just swapped it for a spare drive to see if it keeps occurring. Maybe the issue is a bad drive, or some issue with Slot A? I haven't been alerted to any SMART alerts.

The only way to know for sure is test. Give the disk a SoftRAID disk label. Then connect it in slot C.See if it keeps dropping out, or if the new disk in slot A is disappearing.

So, after replacing the drive in slot A with a new one, I haven't seen a panic or had a drive go missing. I'll continue to monitor, but if I have the patience, I'll put the 'bad drive' in a different slot to see if the panic and disappearing returns. Running some extended smart tests on the 'bad drive' on another machine doesn't show that there's anything wrong with the drive, but I suppose that doesn't guarantee anything.

This is unusual, but electronic devices can start failing in unusual ways.

Seeing the same DART panic as a lot of others. This is with an M1 Mac MBP Pro / Monterey / Softraid 6.2.1b13
If I turn the machine on with the Flex-8 connected (it goes [Mac] ===> [Thunderbolt 3 Pro Dock] ===> [Flex 8]) then I kernel panic about 10 seconds after boot/login. Every time.
I recall reading on a different post that you were planning on driving to Apple with a box - did that ever happen ? If Apple can't currently repo it, I happen to work there, and have done some kernel-driver work, so I know some people. It's *possible* (not probable, but possible) I might be able to help escalate a fix since it happens on my machine.
Do you have the radar number they're using to track the issue ?

We did and have an engineer assigned to this. I don't think you can raise the priority, unless you "really" know someone. We are dealing with a kernel level manager.
There was a two month delay as we found out the engineer was doing something else. But supposedly, it is being working on currently. I can ask about the radar number.

@softraid-support Fair enough :)
If you *can* get me the radar number, I can at least put my info in there and let them know there's another system they'd have "access" to :)
Failing that, I might try some judicious radar searches :)

Let me ask our engineering about this, thanks
