January 19Jan 19 Unraid have been running fine for 1,5 months now after I had to swap a few bad memory sticks.I have not been accessing it for a few weeks, but when accessing today I found none of the dockers started. Obviously because of the error my Cache drive.I tried rebooting, but I don't really understand the diagfiles. Any help on this is greatly appreciated.tower-diagnostics-20260120-0012.zip
January 20Jan 20 Community Expert Type btrfs rescue zero-log /dev/nvme0n1p1 then restart the array and post new diags.
January 20Jan 20 Author After doing this it seems the cache pool started up again, at least for now. Here are the diags.selje-tower-diagnostics-20260120-2047.zip
January 21Jan 21 Community Expert Pool mounted but still has some issues; as a first step, recommend running memtest, since btrfs is detecting data corruption on both devices.
January 21Jan 21 Author Ok. Will do that. If this AGAIN is memory errors, it is the 3rd time in 1 year. Wonder what to do if it is again the same thing.
January 21Jan 21 Community Expert If you had RAM issues before, the errors could be old ones, unless the stats were reset, they don't reset on their own or with a reboot:
January 21Jan 21 Author Oh, no. You were definitively right again. Several 1000 errors on the first memstick pair (the one I changed) in november. I have to pairs with 2x8gb on each stick.Running a test on the other pair now... will post result on this... And a new diag file if this pair does not fail.
January 21Jan 21 Author Last 2 memory sticks comes back perfect. Here are the newest diags.selje-tower-diagnostics-20260121-1825.zip

My recommendation would be to back up and reformat the pool
January 21Jan 21 Author Backup and reformat the cache pool then I guess? Would not a backup now of the cache pool bring the errors back into the new pool?
January 21Jan 21 Community Expert 3 minutes ago, tormi said:Would not a backup now of the cache pool bring the errors back into the new pool?Nope, since it will be a new filesystem.
January 21Jan 21 Author Hmm... Finally got my hardrives back up and running. I moved the backup of my cache - back to the cache, but I now get a message that I don't have any "No Docker containers installed". The docker.img is copied back to the cache... selje-tower-diagnostics-20260121-2348.zip

January 23Jan 23 Author Server has been up and running for 1,5 days now. It seems like all is ok from my side, and I have Dockers up and running again.selje-tower-diagnostics-20260123-1017.zip If anybody wanna do a hopefully last check of the diag file I would greatly appreciate it.
