Remove drive from cache pool

Go to solution Solved by JorgeB,

Recommended Posts

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.

For some reason your pool is set to raid0 in the cfg:




Edit /boot/config/pool/cache.cfg and change that to raid1 and then try again, I would think an array start/stop would be enough, but try rebooting if you still see the same after the change.
