One Disk had Read Errors - Started Rebuild --> During re-build a second disk had Read Errors

[champion01]

Hello all,

 

I have tried to diagnose this myself, but reading the diagnostics is a bit foreign to me.  I don't quite know what I am looking for other than the obvious. I looked at the syslog.txt and saw this line:

Nov 20 17:22:45 TOWER kernel: blk_update_request: I/O error, dev sde, sector 237609224 op 0x0:(READ) flags 0x4000 phys_seg 128 prio class 0

 

Not sure exactly what that means. I have ran SMART tests recently and have not seen any errors.

 

Perhaps its an issue with my LSI Card? I have (2) of these -->  (LSI SAS 2008 9211-8i - IT Mode)

 

You can see in my screenshot that I am currently rebuilding Disk 6, then had Disk 1 fail during the rebuild.

 

Questions

 

* What is going wrong with the server that is causing the Disks to Fail?

* Teach a man to fish please, what areas should I look at in the Diagnostics, in the Syslog.txt only? Or other places?

 

Thanks all

It's not logged as a disk problem, and that usually means power/connection issue.
