krusty003 Posted April 3, 2021 Share Posted April 3, 2021 (edited) Hey guys, woke up this morning and noticed that one of my data drives has a red cross next to it and it says that the device is disabled. I've been using Unraid for a while and have been really fortunate to never have experienced this before so this is all kinda new to me, and I've been able to resolve any issues I have using other posts in General Support but not this one. The drive is newish (about 6 months old) and the server is just sitting undisturbed, no power issues, and is protected by a UPS. Did a filesystem check and didn't show any errors. Stop/start the array, shutdown and checked the cables then power it on, no luck. Parity seems to be ok and the data on the drive is being emulated with no issues. Is this drive actually dead? Or is it salvageable? Really appreciate any help/suggestions anyone can give of what I should do from here. Thanks in advance! tower-diagnostics-20210403-1500.zip Edited April 5, 2021 by krusty003 Quote Link to comment
itimpi Posted April 3, 2021 Share Posted April 3, 2021 The SMART information for the drive looks OK so it could have just been a temporary glitch that caused a write to the drive to fail. If you want to make sure you could try running an extended SMART test on the drive. Worth pointing out that if this happens again you are likely to get better informed feedback if you provide your system's diagnostics zip file (obtained via Tools->Diagnostics) before rebooting the server so we can see what lead up to the drive being disabled. If you want to try and continue using the drive then instructions for rebuilding a drive onto itself are here in the online documentation that can be accessed via the Manual link at the bottom of the unRaid GUI.

krusty003 Posted April 3, 2021 Author Share Posted April 3, 2021 Thanks for looking into that, I've just started the rebuild on to the same drive. Hopefully it all goes well, I'll post an update once it completes. Sorry I forgot to mention in my original post that the diagnostics I attached was from before the reboot - so the syslog probably goes back to when I installed 6.9.0, and the failure occured early in the morning today (Apr 3 01:19 in the logs).

itimpi Posted April 3, 2021 Share Posted April 3, 2021 Did not look at the diagnostics as you mentioned you had rebooted. Now I look at them I see there is was I/O error on the disk so it is possible there really is a bad sector. However if that is the case it could get reallocated next time it is written.

krusty003 Posted April 4, 2021 Author Share Posted April 4, 2021 Rebuild seems to have completed successfully with no errors. Not showing any reallocated sectors. Should I do anything else? Or is it safe to call it a day? Quote Link to comment

Rebuild finishing correctly is a good sign so you are probably good to go May want to run an extended SMART test as a confirmation but that is probably unnecessary. Quote Link to comment
krusty003 Posted April 5, 2021 Author Share Posted April 5, 2021 I did an extended SMART test anyway and it completed without error. Thanks again for all the help!! Quote Link to comment
