After having some issues with one of the cables in my server, I decided to run a non-correcting parity check.  After 37.1% (of 10TB) it is showing 2864 errors detected.  I'm not sure if I have another bad cable or if the onboard SAS controller on my motherboard is having issues.   Diagnostics file is attached.

Some sync errors after an unclean shutdown are normal, even expected, run a correcting check.

 

You also had some issues with your cache, syslog is missing some time due to spam, it appears you already dealt with it, but still good to take a look here.

Correct, the cache was due to a bad cable.  Replacement cable will be arriving today, and I might even get time to install it but likely not until this weekend (darn small kids).

 

Running a cache scrub (I think its now the 3rd or 4th one since I moved cables around) as well as a correcting parity check.

 

Going to cross my fingers that everything is good.
