parity check stalled out at 40.5%

[bdee1]

I just decided to to a parity check because I haven't done one in a while and it seems to have stalled out at 40.5%.  In addition the web guy is incredibly slow at the moment. 

 

I have posted my syslog below.  Can someone please take a look and let me know their thoughts?  I see a lot of disc read errors and timeouts so I am assuming that is bad.

That looks like a problem with the parity drive, and it has probably dropped offline.

 

It could be something like a connection or power supply issue.    I would shutdown the system, check all connections and bring it up again to see if that fixes an issue.  Also a SMART report on the drive would be a good idea.

I have a spare drive so once I check the connections I may swap out the drive. Is there anything special I have to do to replace the parity drive or is it just like replacing a standard drive?
