Hello guys.

I've been having a number of errors with my system and it seems to be very sad for itself.

I've attached the diagnostics - could someone point me in the direction of a starting point in my hunt for my errors.

Regards,

Iain.

Have you done memtest recently?

Do you have a current flash backup?

Yes and no - I ran MemTest several times as I seemed to have a kernel failing error - but the last run overnight gave no errors in 9 passes.

No I haven't got a flash backup - have I corrupted it?

You should always have a current flash backup. All of your configuration is in the config folder on flash. Every setting you have made in the webUI, including your disk assignments, docker templates, share settings...

See if you can copy config folder from flash drive, then create a new install and see if it will boot. If that is OK, put your config back on flash.

OK - new flash drive worked. Re-copied existing config. Booted and I'm getting this...

new flash drive

Didn't specifically ask you to do that, just a new install. If you change flash drives you have to transfer license.

Still seeing those SQUASHFS errors which typically means corruption on flash, though it could have been from the config you copied back.

Boot in SAFE mode and see if it will work.

Ok - how do I do a new install without screwing up my current data drives - I have copied all my config off of the flash drive.

BTW - safe mode seems to still have all the squashfs errors

You can try putting just some of config back on a new install.

Your drive assignments are in config/super.dat and config/pools.

If that works we can go on and see what else might be recovered.

Still wonder if you don't have a RAM or other hardware issue.

I’ll try that in the morning - and run another memtest to see if that’s an issue.

Cheers.

I see that you have a 14900K, those are very susceptible to the Intel 13/14 gen issues. Look for a BIOS update; it may help if the CPU is not too far gone.

I can’t find a later bios from CWWK than the one that I’m running now ☹️

Ok - I’m running MemTest at the moment - all seems well.

For my own sanity, can someone please check that my proposed next steps are corrent.

1. Power down and pull the flash disk out

2. Put the flash into my Mac and copy the config folder off of it.

3. Use the USB Creator tool to flash with the latest UnRaid release.

4. Put the flash disk back into my machine and power up.

5. Watch the see you soon syslog for errors and pray the gods that it’s clean.

Iain.

Ok - I've done that - recovered the licence key and rebooted but I'm still seeing squashfs errors in the logs. As well as other errors.

Is my CPU fried? and if so can I simply get a RMA and drop in the replacement - will this cpu still be plagued by errors when I can't find a later bios than the one installed?

I'm really stuck here - its been pottering on for 8 months and only now when I've started to populate it do I have all these errors.

All help appreciated.

Regards,

Iain.

Assuming this is a new flash drive, you can try with just one stick of RAM at a time; if the errors persist, it's most likely a bad CPU.

I'm going to close this thread down for now.

My plan is to spend the next few days copying my data back to my venerable old Drobo for safety.

Then I will update the bios with one I've found in the depths of the CWWK website.

Then I will run Memtest86+ for a few days to see if I get any errors.

Then I will boot into a Linux distro so I can run Prime95 for a while.

If that all runs clean, then I will get a new flash drive and start a new install and try again.

Otherwise I will have to RMA the CPU and hope that I get a good one in return...

Thanks for your help so far.

Regards,

Iain.
