Can someone please try to shine a light on the errors I am getting here. 

 

The system was doing its monthly parity check and now it is saying that the Parity Disk is in error with read and write errors. I have captured a syslog, attached, and am trying to download the diagnostic file which is still going after a good 10-15 minutes (is something wrong there?)

 

I am loathed to turn the system off until I have captured the diagnostics.

syslog 031220.txt

Since you have already given us syslog, and parity is going to have to be rebuilt anyway, it is OK to get us Diagnostics after rebooting.

OK,

 

Rebooted and now the diagnostics works and I have attached. 

 

Any ideas about what is going wrong and what I should do next?

No obvious SMART problems with parity. Run an extended SMART test on it.

 

You really should consider dual parity with that many disks. Are you sure power is OK for that many?

Pretty sure, it is a NetApp DiskShelf with 4 PSU's and a Dell R710 with 2 PSU's. 

 

(Whether the wall socket can take it is another matter , but it does not draw as much power as you would think)

Mmmm not convinced by the Extended Smart Self Test, it's been going for the best part of a day now and it is still at 20%, even on a 14Tb drive that seems a bit long. 

 

Doesn't it?

You can see how long it's expected to take by looking at the SMART report:

 

Extended self-test routine
recommended polling time:      (1542) minutes.

at 20%

Also that's usually the remaining %.

 

 

Extended Smart Finished without error.

 

I have attached the diagnostics, any ideas what to do?

Swap both cables with another disk to rule them out and re-sync parity.

I have taken it out, put it into another caddy (there are no cables as it is a Disk Shelf) and am rebuilding parity.
