EC28 Posted November 12, 2023 Share Posted November 12, 2023 So I had a ton (3TB) of newgroups "article" downloading and woke up and my cache drive has possibly died. Hopefully this is recoverable. I do have a mirrored cache, but my the array isn't working of course due to an invalid config now and all of my docker and VM is gone. Is it possible to recover?

JorgeB Posted November 13, 2023 Share Posted November 13, 2023 Try power/cycling the server to see if the missing device comes back. If the pool was mirrored (raid1) you can start with a device missing, it would still work, assuming the pool didn't have any other issues. 1 Quote Link to comment
EC28 Posted November 13, 2023 Author Share Posted November 13, 2023 Tried that already but it's worth a shot doing it again. Used the powerdown command to fully shut it off and I'll give it a few minutes to see if it'll help. Thanks for jumping in to help. Quote Link to comment
EC28 Posted November 13, 2023 Author Share Posted November 13, 2023 Ok, somehow it found it now. Docker didn't start though. Going to try to start it manually and maybe reboot again. Quote Link to comment

EC28 Posted November 13, 2023 Author Share Posted November 13, 2023 Yeah, docker won't start for some reason. My VM is working fine. unraid-diagnostics-20231113-0758.zip Quote Link to comment

JorgeB Posted November 13, 2023 Share Posted November 13, 2023 Scrub the pool to bring the dropped device up to sync, then if there are no uncorrectable errors re-create the docker image, also see here for better pool monitoring, the device dropped a while ago. 1 Quote Link to comment
EC28 Posted November 13, 2023 Author Share Posted November 13, 2023 Do I check repair corrupted blocks? Quote Link to comment
EC28 Posted November 13, 2023 Author Share Posted November 13, 2023 Gotcha. Looks like about a 6 hour run. We'll see. Thanks for all your help so far. Quote Link to comment
EC28 Posted November 13, 2023 Author Share Posted November 13, 2023 Starting to see some strange things going on with it. Is this ok? Quote Link to comment
EC28 Posted November 13, 2023 Author Share Posted November 13, 2023 I think that fixed me up sir. Thank you so much for your help. I created the user script to run the scrub every week and check for errors. Anything else I need to do? Quote Link to comment
EC28 Posted November 14, 2023 Author Share Posted November 14, 2023 One thing I've noticed is that when I run the script to check for errors, it's still showing all the errors from earlier. Any thoughts on that? Quote Link to comment
JorgeB Posted November 14, 2023 Share Posted November 14, 2023 All errors were corrected, that's good, and in the FAQ entry it mentions how to reset the stats. Quote Link to comment
EC28 Posted November 14, 2023 Author Share Posted November 14, 2023 That fixed it, thanks! 1 Quote Link to comment
EC28 Posted November 18, 2023 Author Share Posted November 18, 2023 So....it happened again. Guessing I might have an issue with that drive? I was able to recover it the same as before, but this is popping up now. And I'm not seeing that plugin in the nerdtools pack. unraid-diagnostics-20231118-0842.zip Quote Link to comment
JorgeB Posted November 19, 2023 Share Posted November 19, 2023 Assuming the stats were reset the device dropped offline again: Nov 16 21:50:23 Unraid kernel: BTRFS info (device sdb1): bdev /dev/sdb1 errs: wr 92704976, rd 33512, flush 67810, corrupt 0, gen 0 If you haven't yet replace both cables, if it keeps dropping replace the device.
