Hello Hugo,
thanks for your hint.

Here's your problem -- you've got a RAID 5 filesystem, which has a
minimum allocation of 2 devices, but only one device has free space on
it for allocation, so no more chunks can be allocated. I'm not sure
how it ended up in this situation, but that's what's happened.
2) convert a few chunks of the existing FS, on devices 1 and 3, to
single, which should free up some space across all the devices, and
then run a full balance, and finally convert the single back to RAID
5:
# btrfs balance start -dconvert=single,devid=1,limit=4/mnt/__Complete_Disk
# btrfs balance start -dconvert=single,devid=3,limit=4/mnt/__Complete_Disk
# btrfs balance start -dprofiles=raid5/mnt/__Complete_Disk
# btrfs balance start -dconvert=raid5,soft/mnt/__Complete_Disk
I did that. In order to run the first two commands I had to free some
space though, which was no problem.
Now the output is:
root@homeserver:/media# btrfs fi df /mnt/__Complete_Disk
Data, RAID5: total=3.79TiB, used=3.78TiB
System, RAID5: total=32.00MiB, used=416.00KiB
Metadata, RAID5: total=6.46GiB, used=4.85GiB
GlobalReserve, single: total=512.00MiB, used=0.00B
root@homeserver:/media# btrfs fi show
Label: none uuid: a8af3832-48c7-4568-861f-e80380dd7e0b
Total devices 3 FS bytes used 3.79TiB
devid 1 size 2.73TiB used 2.43TiB path /dev/sdf
devid 2 size 2.73TiB used 2.43TiB path /dev/sdd
devid 3 size 2.73TiB used 1.38TiB path /dev/sde
How can only 1.38TiB be used on devid 3?
Greetings,
Hendrik
