Hi,

 

I was going to do a Thanksgiving upgrade from 6.9.2 to the latest version of unraid. Before I could start, I had a disk fail, i removed the disk started the array, and then added the disk back so it could rebuild. The smart information looked ok to me but I am not an expert. All of a sudden another disk (Disk 7 has read errors) Disk 8 was the one that failed. Both are shucked 14tb and 12 tb wd drives that are less than a year old. 

 

Right now it is trying to rebuild the array but showing read errors on Disk 7 while it is rebuilding disk 8. I have 1 parity drive and that seems to be ok. 

 

What can do I do to see what's going on and the drives are less than 36C all the time and in a well ventilated tower case (Define 7 XL).

 

Diagnostics are attached. 

 

Thank you,

Just in case this helps I have a IBM 46M0997 ServeRAID 16-Port SAS Expander Expansion Adapter plugged into a IBM H1110 SAS Card (I think 9211-4i FW 9211-8i P20 IT Mode is the equivalent but I am not sure)

Diags you posted don't show any disk7 errors, maybe you've posted the wrong ones?

Jorge, I am rebuilding the array again, so will wait for the errors to show again. There was like 12 million read errors for disk 7., disk 8 is rebuilding now. 

Hi Jorge, here is the logs from the diagnostic with errors for disk 7.

Disk7 dropped offline, this is usually a power/connection problem, cancel the rebuild check/replace cables and try again.

 

P.S. you also need to check filesystem on disk8.

Will do
