tuxbass Posted June 6, 2022 Share Posted June 6, 2022 (edited) Out of the blue got following notification: Quote Unraid Parity disk error: 06-06-2022 22:20 Alert [TOWER] - Parity disk in error state (disk dsbl) WDC_WD40EFRX-68N32N0_WD-WCC7K1VRDCFN (sdc) Starting SMART tests via UI does nothing, smart error log is empty. Parity drive is WDC_WD40EFRX-68N32N0_WD-WCC7K1VRDCFN, sdc. Including diagnostics file: tower-diagnostics-20220606-2221.zip How should one proceed? Reboot and see if it's possible to run SMART test?

Solution JorgeB Posted June 7, 2022 Solution Share Posted June 7, 2022 Jun 6 17:49:41 Tower kernel: ata4.00: disabled Disk dropped offline, this is usually a power/cable problem, before it dropped there are several ATA errors logged, same for the SSD, check/replace those cables and post new diags after array start.

SSD/cache drive has been dripping those errors since almost day 1. Swapping cables around nor re-seating cable sockets hasn't improved it. Now looking, it seems the error count increase has sped up - used to be in the hundreds, now climbing into thousands... So, I rebooted the server. It came back with no parity assigned to array at all. - stopped array - went to 'Array Devices' tab to re-assign it - but it's not even listed! Seems like a complete connection error? Attaching post-reboot diags (with array stopped though) Guess best bet is to keep the array stopped, crack the case open and wiggle some cables? tower-diagnostics-20220607-1139.zip Quote Link to comment
itimpi Posted June 7, 2022 Share Posted June 7, 2022 It could also be a power issue - especially if you are connecting more than about 4 drives to a single cable from the power supply, or using splitter cables that can sometimes be problematic. Quote Link to comment

tuxbass Posted June 8, 2022 Author Share Posted June 8, 2022 After wiggling the cables for a 3rd (!) time the parity drive is listed again. Running extended SMART tests overnight, then rebuild the parity. Is it possible the issue is caused by ageing setup? Living in a coastal subtropical zone and computer is now 6+years old - some metal bits on mobo are visibly corroded. 1 Quote Link to comment
tuxbass Posted June 9, 2022 Author Share Posted June 9, 2022 Parity rebuild was uneventful, array started back up a-ok! Likely unrelated, but all docker world collapsed on me. Started another thread. Quote Link to comment
