Hey guys I need some help. I haven't been able to figure this out. My server has been working great for 2-3 years+ and this is the first time I am encountering this issue.

Recently, my HBA card started causing errors (I'm pretty sure it was the problem) and I thought some of my disks had died. I put in another HBA and all the discs were recognized no problem. Of course a data rebuild starts and completes successfully. Now I am trying to complete a Parity Sync but when I come back to my server around the time it is supposed to have finished, I find that the server has restarted and the parity sync was cancelled. This is with no interaction with the server. I found that there was a mce hardware error in the logs after one of the reboots so I did a memtest and everything came out clean.

I have dual parity with 14TB disks (one of these was one that disappeared when I had the HBA problem) and 5x 12TB disks on the array (one of which also disappeared when I had the HBA problem). Both disks worked when I tried the new HBA and I had no data loss. However Parity Sync still does not complete and the server reboots.

Some help would be greatly appreciated.

You can try enabling the syslog server to see if it catches something but it looks more like a hardware problem, like PSU or overheating server.

Ok I'll try to obtain some logs via the server you mentioned. This time I am running parity with the problematic parity disk removed so lets so if that changes anything. 

Turns out it was my HBA card that causes disks to go offline which caused other downstream issues even when I connected the disks directly to the motherboard. I got a new HBA and parity synced everything and its all working perfectly. The problematic disks were not the issue
