I'm trying to replace my cache pool made up of a 1.2TB and 1.92TB SSD drives with a single 3.84TB SSD. I have the pool as Raid1, however when I stop the array and try to remove a drive to make it a single drive cache pool, it says Wrong Pool State, too many missing disks. I've gone through forum posts, and figure I must be missing something simple. Can someone point me in the right direction?
Essentially I want to Remove the 1.2TB drive, leaving the single 1.92TB drive, then add the 3.84TB drive making it Raid 1, then eventually remove the 1.92TB drive with another 3.84TB drive.
