February 26, 20197 yr So after a headache trying to remove a ssd from a cache pool, I am now having issues trying to do anything like balancing. Worst part is I cannot even change from btrfs to xfs on the disk. It just shows auto, btrfs, and btrfs encrypted. I thought xfs was suppose to be in there (which I want). On top of that, it's showing 1TB total free space when it should be half of that since I had identical drives. Right now running a balance gives output of: root@Tower:~# btrfs balance start -f -dconvert=single -mconvert=raid1 /mnt/cache Done, had to relocate 3 out of 3 chunks
February 26, 20197 yr Community Expert How many cache slots do you have allowed? If it is more than 1 then only BTRFS types are allowed as the other types do not support having a cache pool.

February 26, 20197 yr Community Expert Weird, with the array stopped edit /config/disk.cfg and change cacheFsType="btrfs" to "xfs" start the array and you should be able to format it xfs.

So far so good. Back to 1 disk cache with xfs. However, are there any clean up commands I can use on both of my ssd disks(1 cache, 1 unassigned) to ensure no traces of irregularities? Thanks by the way.

Reformatting the disks should effectively erase the current contents.
