Hi All


Im having an issue with BTRFS, I have added a second cache drive and when I try to do the ballance it fails. with 

kernel: BTRFS error (device sdi1): balance: invalid convert metadata profile raid1

Ballance looks like this 


Data, single: total=25.00GiB, used=23.93GiB
System, single: total=32.00MiB, used=16.00KiB
Metadata, single: total=2.00GiB, used=53.83MiB
GlobalReserve, single: total=16.00MiB, used=0.00B


No balance found on '/mnt/cache'


I ran 

-dconvert=single -mconvert=raid0

And then I tried it in the console and got

[ 9856.213350] BTRFS error (device sdi1): balance: invalid convert data profile raid0


Here is what my drives look like

Pool is only one device, despite two being assigned, stop array, unassign cache2, start array, stop array, re-assign cache2.

Also this isn't a recommend profile, -d is for data, -m is for metadata, after the pool is correct and if you want raid0 use:

-dconvert=raid0 -mconvert=raid1


if you want raid1:

-dconvert=raid1 -mconvert=raid1
