July 14, 20232 yr As title says system is (mostly) unbootable. At best it boots to shell and hangs after a short while regardless of which boot option I choose. GUI not available at all. Some of the errors: Jul 12 01:23:27 Tower kernel: SQUASHFS error: xz decompression failed, data probably corrupt Jul 12 01:23:27 Tower kernel: SQUASHFS error: Failed to read block 0x39dafbc: -5 Jul 12 01:23:41 Tower kernel: SQUASHFS error: Unable to read fragment cache entry [102ea8ec] Jul 12 01:23:41 Tower kernel: SQUASHFS error: Unable to read page, block 102ea8ec, size 7e58 Jul 12 01:24:49 Tower kernel: kernel BUG at drivers/md/unraid.c:1617!

I have swapped GFX card and get another new error (not in this diagnostic) : loading /lib/firmware/amdgpu/sienna_cichlid_smb.bin failed with error -5 RAM passes full memtest run. I have unplugged all array HDDs and plugged in brand new spare HDD and installed bare metal Windows. Bare metal machine works stress-tested on that spare drive. tower-diagnostics-20230712-0127.zip

July 15, 20232 yr Author Following your advice I created an image of current USB, formated it and used unRaid USB Flash Creator tool to make a clean unRaid install. Booting clean from same USB flash device produces unstable system. At this point it is evident that the old USB flash drive is done for and I will need to use a new one. I've then went out and got a new Kingston Data Traveler 3.0 (unfortunately no 2.0 USBs were available to buy at any of the local stores). I've formated it and made a new clean install. Booting from new device results in clean bootable system with no errors: unRaid loads, you can access GUI and it shows all disks missing and array is stopped since all my discs are disconnected. I've then downloaded my flash backup from unRaid Connect and copied it over to the new key. This also produces unstable system with errors: unRaid fails to load or hangs, if it manages to load GUI Firefox crashes, etc. It seems that part of corruption from flash device have been backed up?!? At this point I believe best thing would be to start with new flash device and preserve only shares settings, docker settings and vm settings from my backup. Which files/folders I need to copy over to new flash device to preserve those settings? Edited July 15, 20232 yr by Lavoslav

July 29, 20232 yr Author The problem is still ongoing and is driving me up the wall. I've attempted with new flash device, but as soon as I update something, download anything, try disk access - machine goes berserk. I did in depth troubleshooting on hardware and I believe motherboard is the culprit as nothing else makes sense. At this point I'm in contact with motherboard manufacturer to see what they say. For now I've transferred my essential services on a spare Q-nap I had lying around and am awaiting their response.
