I have a very large array - 24 drives, all 10,12, or 14 TB. A couple of weeks again I started having issues with the parity drives getting disabled. I was told to ditch my Marvel based controllers, which I did. I bought two LSI 9201-16i cards and installed them. I still had issues. I was told my firmware is very old, so I updated to the latest. I thought maybe the drives were faulty, so I bought new 14TB drives for parity. I've swapped my cables I don't even know how many times at this point. I moved the server out of my network closet to a cooler room.
Every time I made a change I had to start the parity build over. With this many drives it takes several days to complete. Most of the time, it doesn't complete. It did complete once, and a few hours after completion a data drive was disabled, taking all it's data offline.
Yesterday I moved the server and updated the controller firmware. Now I have read errors on 3 drives and unraid has disabled one of the parity drives.
I'm pulling my hair out with frustration. I've swapped out all the hardware short of building a new server from scratch. I need to nail down the actual issue and get my server back.
Please help!
