[unraid v6.12.4] disks erroring/failing? udma crc errors, other webgui problems

Featured Replies

Hey all,

Relatively new to unraid, previously was using truenas, and after some help diagnosing a few issues I've been experiencing.   Have had ongoing issues with a disk that would error, be put into a failed state and prevent unraid from shutting down or spinning down the array.   So first question is why would a failed disk in an array completely prevent shutdown or array spin down? 

I have just replaced that drive which fixed the above issue.  But now I have a second disk that has started spitting out errors.  At the moment they appear to be udma crc errors.  I have previously checked all connections to the disks and have now just reseated all the hotswap bays and moved the erroring disk to another bay to rule out further any hardware issues with the bays themselves.

I have taken my array offline for now and I'm running a long SMART test on the errored drive.  Waiting to see what that brings back...

I just want to get my head around what is actually happening with the disks and the array.   It's weird, coming from truenas unraid seems more difficult and harder to understand what is actually going on.  For me, truenas just worked and was bullet reliable; whereas unraid I seem to be nervous every time I check on the server in case something else is wrong...

Appreciate any help.

I will attach the diagnostic file in the first post.
Apparently, I can only post 1 message per day??? So will attach the diagnostic file here...

Constant errors on disk3:

Looks more like a power/connection issue, replace cables.

Hey thanks for checking that out for me.   dev sdj matches the disk I just pulled out and replaced that was originally failing.

For reference, current disks are labelled:

boot drive - sda
array  - sdb, sdc, sdd, sde, sdf, sdg, sdh, sdi

I might still replace cables just in case though.

The fact that it's sdj makes me think that it's a false positive...

Reboot to clear the logs and post new diags after the problem shows up again.
