System has been unstable (mostly locking up randomly) requiring hard reset.

MB was bad. Replaced. All good for about two weeks.

Cache drive (singular SSD) failing, replaced with two (2) new SSD in RAID 1 pool.

PCIE SAS/SATA card failed after everything got moved around, thankfully. Replaced card.

New SSD's in pool 'cache' and appear to be working; however, the drive lights constantly stay on...?

ONLY WAY to get the system to boot is in SAFE MODE.

I am able to start Dockers (image file replaced with new as system would hang before when starting Docker), they seem to be working.

Rebooted 2-3 times at this point, in Safe Mode and all appeared well.

*****UPDATE 2 hours later....now every Docker is hanging. Tried rebuilding image, but now that is hung too.... Sigh...

Tried to run Parity check...nothing. Button lights up, click...nothing. Tried to reboot from GUI...nothing. Doesn't matter what I clicked on...nothing. Had to hard reset again.

Got system back up, in Safe Mode, got the 'log file' but Diagnostics hung where doc shows.

I just shut down my desktop in frustration. Came back about 15 minutes later (cold one in hand) restarted desktop, logged into server (still in Safe Mode) and Diagnostics ran.

I do not know what else to look at other than a corrupted file in the USB and I have no idea (sort of) what I am looking at in the logs or diagnostics.

*******#2 UPDATE - anyway to "rebuild the appdata and Docker on the Flash USB ?

ANY help GREATLY appreciated!!!!

Log and Diagnostics attached. Also attached word doc showing how far diagnostics got the first time before it hung.

Thanks everyone.

Update #2

Unraid driver is crashing, this is almost always a hardware issue, typically RAM, CPU or board.

@JorgeB Thank you for getting back to me!

So, am I able to throw together another box and stick the existing Flash drive (could it be the flash drive that's bad?)

and (potentially) have a stable system again? One that has the exact config as the current?

Of course now that I think about it, the Flash only 'holds' the Unraid system between boots etc., right?

Or am I going to have to rebuild everything (Unraid-wise), Dockers, Plugins, custom networks, and so on?

*****UPDATE/Question: Just to make sure it is not the Flash drive itself, is it possible to get a new flash drive and simply copy the contents of the old one over to the new one? Test it, then if it works, get with Unraid to get the flash drive ID's changed? (Regardless, can this be done at all? Just for future knowledge...)

ALL my Cloud info is on there, on a single drive with dual parity. I know (backup), but I thought the dual parity would cover me in the event of a catastrophic failure.

Thanks again for sharing your knowledge.

Spelling and deeper question

Very unlikely, but you can try replacing it

Replaced basically everything, piece by piece. The last was the Cache SSD's (Cache is now RAID 0).

System has been stable for about 2 weeks now.

Guess we'll see!

(Thanks JorgeB for your input)
