August 22, 20223 yr We had a power failure over the weekend and I just got around to starting my array again. It required a parity check upon restart and during the parity check (read-check) I got disk errors from one disk. Not sure how to tell if this is a real disk failure situation or something that can be ignored because of the recent power failure. Thanks in advance for any help/insight. tower-diagnostics-20220822-1357.zip
August 22, 20223 yr Community Expert Looks more like a power/connection problem, but since the disk dropped offline there's no SMART report, check/replace cables and post new diags after array start.
September 5, 20223 yr Author Finally got around to checking the cables and restarting. The SMART is there now. Does the drive seem OK? If so what do I do to re-enable things? tower-diagnostics-20220905-1527-array-start.zip
September 6, 20223 yr Community Expert Disk looks OK, suggest replacing/swapping cables to rule that out and then rebuild: https://wiki.unraid.net/Manual/Storage_Management#Rebuilding_a_drive_onto_itself
September 6, 20223 yr Author Thank you so much for your interpretation of my diagnostic files and your help!
September 18, 20223 yr Author Ugh, another disk went disabled and not sure why (sdb). Can you take a look at this diagnostics before I stop the array and shut down again? tower-diagnostics-20220918-1039.zip
September 19, 20223 yr Community Expert Still having issues with multiple disks, looks more like a power/connection problem.
