Hello. My unraid 6.8 system had run flawlessly for the past 5 years until last week when both Docker and VM went down. Docker gives a "Docker failed to start" message and VM showed that I had no VM's. Oddly enough the cache drive had vanished as well. Then it reappeared as an unknown drive, then... well then things became even more bizarre. I will try to provide a cogent listing of errors along with some screen grabs and a log.

 

Issues

• Cache drive may not appear and unraid shows no device and no device is available to select. Starting array just shows array w/o cache.
• The cache drive may appear as an unassigned drive.
• Reboot may show multiple missing array discs but the missing discs vary from reboot to reboot. The device lists are all empty.
• All drives (including cache) appear but starting the array takes much longer than usual and no VM's are found.
• May get a libvirt error (see below).
• Unpredictable log errors during boot (e.g. ata5 (cache drive) errors 15 & 16, unsynchronized clock, can't find disc, and others.)

 

Things I've done

• Changed the VM libvirt path to point directly to file rather than folder.
• Upgraded to 6.10
• Did a disc check of the unraid USB stick.
• Reboot, shutdown and restart.

 

I'm not able to discern a pattern to any of this and any thoughts are appreciated.

That suggests some kind of power issue, also when all devices appear please post the complete diagnostics after array start.
