March 23, 20233 yr I hope someone can help me find out why the parity drive got disabled. My guess is the CRC errors but I would like some confirmation. Diagnostics attached. Also, what next? Thanks in advance! tower-diagnostics-20230323-2018.zip
March 23, 20233 yr Community Expert Syslog is spammed with SSH related text, so cannot see the parity errors, but SMART looks OK, so replace SATA cable and re-sync.

CRC errors never disable a drive by themselves - it takes a write failure to do that. They most frequently indicate cabling issues (either SATA or Power) and that could lead to a write failure.
March 23, 20233 yr Author Thanks guys. Yes I saw the ssh issue, need to fix that. I had some issues with the tower a while back, took it out and reset all the cables. It fixed the startup issues but might have introduced this issue. I will repeat the process and try again. I has all worked fine for years. I know, I know, time for an upgrade / rebuild.
March 26, 20233 yr Author Hi, I have reset all the cables and restarted. then stopped the array - removed the parity disk from the configuration started array - no parity but all good stopped array - added parity disk back to the array started array and the disk got disabled again. there are some write errors in the logs. I have a spare disk, maybe it is time to swap them over? Could you please have a look at the diagnostics again? (the SSH errors are gone) tower-diagnostics-20230326-1548.zip
March 26, 20233 yr Community Expert Still looks like a power/connection problem, replace the cables and if the same try with a different disk.
