Hi,

First of all I want to thank you for this great piece of software,
I've been using it for a long time and it perfectly suits my needs.

After a unclean shutdown, with a balancing in progress and very little
free space in my RAID1 filesystem I ended up with a btrfs filesystem
that only works in ro mode.
If I try to mount it as normal, any read or write operation will hang
forever, not even "umount" will return.
As a side note, if I mount it as normally I have to force my machine
to power off since the normal shutdown will wait until any filesystem
is unmounted.

Here are my technical details:

uname -a
Linux poloni 4.15.0-111-generic #112-Ubuntu SMP Thu Jul 9 20:32:34 UTC

btrfs --version
btrfs-progs v4.15.1

sudo btrfs fi show

this aa1f67a3-8cd3-4d1b-87de-a04b48efbcfd works fine.
this 5ea692ab-c7b1-4618-be39-d82eaf5c6b34, my-btrfs is the one that
causes problems

btrfs fi df /mnt/
Data, RAID1: total=888.48GiB, used=886.92GiB
System, RAID1: total=32.00MiB, used=208.00KiB
Metadata, RAID1: total=3.00GiB, used=1.97GiB
GlobalReserve, single: total=512.00MiB, used=0.00B

I was willing, but unable, to remove some large files to have enough
free space to operate normally.

I add the dmesg.log file in the attachment.

I wonder if I should try to fix it or if I should format the partition
and recover a backup.

Thanks in advance,
Falk
