Disabled Parity Disk

[roland]

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!

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.

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.

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)

Still looks like a power/connection problem, replace the cables and if the same try with a different disk.
