Ok, to sum it up....
Two of the drives in my pool were having major issues. Drivepool took a long time to start the service (approx 30min), and the drive was severely unstable when it did run.
Removing the drives did not work as the drives, and drivepool were too unstable. Once I physically removed the drives and restarted the server everything came back up in an almost normal way. I then hit 'Remove' on the two drives that were missing.
At this point I do not know if it was the drives or a controller issue, but once the pool remeasures and things are quasi stable, I will look into that and see if I can manage to recover anything from the drives. I am hoping so since that's about 9TB of data
