I'm having an issue where every time the array or system reboots, one of my cache pools RAID1 setup breaks. From what it looks like, UNRAID doesn't see the drive yet it's online within the pool. In order for me to fix this I would need to stop the array, remove the drive from the pool, start the array, stop the array, re-add the drive, the start the array. Then I would need to balance the pool to RAID1. Unfortunately, I have to do this every time the array goes offline. Is there something I can do to resolve this? I've attached screenshots and diagnosticss hopefully someone can help me here.

That pool is in a weird state and it's showing errors in one of the devices:

 

Mar 18 09:03:56 Bakuzan kernel: BTRFS info (device sdb1): bdev (efault) errs: wr 2, rd 0, flush 0, corrupt 2969, gen 0

 

See here for more info on that for the future, for now I would suggest backing up that pool and wiping the devices, then re-create.
