I have 8x2TB drives and 1 of them is my parity drive. A few days ago, I couldn’t access any of my shares and noticed every drive having the same amount of errors, so I restarted the server which restored functionality. A day later, I’m back in the same spot and this time restarted the server and ran parity check which gave millions of errors. 
 

Is my parity drive causing all the issues or are all my drives somehow toast?

Thanks in advance

Controller problem:

Also note that RAID controllers are not recommended.

Welp, now that I double checked all the statuses, the sas controller temp was at 110c which was 10c over the threshold. I shutdown my server to let it cool down and will try turning it back on tomorrow and set fans to run way higher than I set it to. Hopefully it’s not damaged. 
 

I had set the controller to pass through mode over a year ago (IT or JBOD mode if I remember correctly) and had no issues so far.

Apparently not, it is using the RAID driver.
