Re: btrfsck does not fix

Hi Chris,

thanks for your hint.
 >> No. You said you need to recreate the file system, and only have 
these two devices and therefore must remove one device. You can't 
achieve that with raid1 which requires minimum two devices.

And then do another conversion for just -mconvert=dup -sconvert=dup, and do not specify -dconvert. That way the single metadata profile is converted to duplicate.

I think it didn't work.

btrfs balance start  -dconvert=single -mconvert=single -sconvert=single 
--force /mnt/BTRFS/Video/
After >10h:
  btrfs balance status /mnt/BTRFS/Video/
No balance found on '/mnt/BTRFS/Video/'
root@homeserver:~# btrfs fi df /mnt/BTRFS/Video/

         devid    1 size 2.73TB used 1.15TB path /dev/sdb1


(you see that I cleaned up beforehand, so that enough space is 
available, generally).

Do you have an idea what could be wrong?


Thanks and Regards,
Hendrik
