Hi,
I'm having some problems with balancing and I've filed a bug at
bugzilla (https://bugzilla.kernel.org/show_bug.cgi?id=120121), but it
could also be that I've missed something even after more than a couple
of hours reading forums and mailing lists.
If someone could point me in the right direction that would be very
much appreciated.
I tried to migrate from raid1 to raid10 (btrfs balance start /files
-mconvert=raid10 -dconvert=raid10)
This failed after about 1TB with enosp errors.
I have since then managed to migrate all metadata back to raid1 but my
data is still a mix.
I've tried "balance -dusage=50" with all values from 0 to 100, also
with -dprofiles=raid1 and -dprofiles=raid10. I've also tried balance
-dconvert=raid1 (with and without -dprofiles=raid10) but I always get
enosp errors.
I've also added a small usb-drive(/dev/sdh below) to get some space
but it still gives the same error.
Since I have about 1.5TB unallocated space it's my understanding that
this shouldn't be a problem, or am I completely wrong?
