Hi,
I have again the issue of no space left on device while rebalancing
(with btrfs-tools 4.4.1 on kernel 4.4.2 on Debian unstable):
mh@fan:~$ sudo btrfs balance start /mnt/fanbtr
ERROR: error during balancing '/mnt/fanbtr': No space left on device
mh@fan:~$ sudo btrfs fi show /mnt/fanbtr
mh@fan:~$ sudo btrfs fi show -m
Label: 'fanbtr' uuid: 4198d1bc-e3ce-40df-a7ee-44a2d120bff3
Total devices 1 FS bytes used 116.49GiB
devid 1 size 417.19GiB used 177.06GiB path /dev/mapper/fanbtr
mh@fan:~$ sudo btrfs fi df /mnt/fanbtr
Data, single: total=113.00GiB, used=112.77GiB
System, DUP: total=32.00MiB, used=48.00KiB
Metadata, DUP: total=32.00GiB, used=3.72GiB
GlobalReserve, single: total=512.00MiB, used=0.00B
mh@fan:~$
The filesystem was recently resized from 300 GB to 420 GB.
Why does btrfs fi show /mnt/fanbtr not give any output? Wy does btrfs
fi df /mnt/fanbtr say that my data space is only 113 GiB large?
btrfs balance start -dusage=5 works up to -dusage=100:
mh@fan:~$ sudo btrfs balance start -dusage=100 /mnt/fanbtr
Done, had to relocate 111 out of 179 chunks
mh@fan:~$ sudo btrfs balance start -dusage=100 /mnt/fanbtr
Done, had to relocate 111 out of 179 chunks
mh@fan:~$ sudo btrfs balance start -dusage=100 /mnt/fanbtr
Done, had to relocate 110 out of 179 chunks
mh@fan:~$ sudo btrfs balance start -dusage=100 /mnt/fanbtr
Done, had to relocate 109 out of 179 chunks
mh@fan:~$ sudo btrfs balance start /mnt/fanbtr
ERROR: error during balancing '/mnt/fanbtr': No space left on device
mh@fan:~$
What is going on here? How do I get away from here?
Greetings
Marc
