Hello,
After a reboot I am lost with an unmountable BTRFS partition. Before
reboot I had first compile problems with freezing IntelliJ. These
persisted after a first reboot, after a second reboot I am faced with
the following error after entering the dm-crypt password (also after
manual mount with -o ro,recovery, see attached dmesg):
[ 6098.921985] BTRFS error (device dm-0): unable to find ref byte nr

I've searched for a solution on the web, but most articles tell to do
nothing, but write to this mailing list. So my hopes are that you can
shed some light into what I can do.
I've found a quite recent thread here
(https://lore.kernel.org/linux-btrfs/5b0d2e94-6e4e-aecd-3eda-459c4a96bb13@mokrynskyi.com/)
but this just mentions a fix for 'Fix missing reference aborts when
resuming snapshot delete' and is not further specific.
Setup of my SSD looks like:
* efi
* dm-crypt plain. Contains BTRFS (w/o lvm or similar). Several
subvolumes (/, /home, ...)
* swap
I've already run btrfs restore on volid 258 (home) and gathered lots
of data from the disk (>200GB). I also have a dd backup of the
cryptroot after the failure happened (in case something goes wrong).
Besides I did not do any fix attempts yet. If there is anything I can
do to get the system working again, I'm happy to hear.
Thanks!

This suggests a crash or power failure, as there's a log that needs to
be replayed to mount the file system, but that log replay has failed.
Try:
mount -o ro,nologreplay <dev> <mp>
If that works without additional errors, go ahead an unmount. If
you're willing to take a small risk of the last, maybe minute or so of
transactions being lost, and you need to get up and running sooner
than later, you can zero the log.
btrfs rescue zero-log <dev>
However, it might be useful to try and provide more information first
because log replay should not fail.
btrfs insp dump-s -f <dev>
From that you will see an item log_root and a number after it. Copy
that number and paste it in here:
btrfs insp dump-t -b <logtreeaddr> --follow <dev>
I'm not sure how much information btrfs dump tree can provide about
log trees, but worth a shot I guess.

Hmm, that's possibly getting tripped up on the log. I'm not sure. So
I'm still curious if it can mount ro without log replay. That's a safe
command, it doesn't make any changes on disk. If it works, you can
back up some files while you have the chance in case repair attempts
don't work or things get worse.
Obviously the less you change the system (zero log, and check --repair
both write to the file system and change it) the better off you are
until a developer can give advice. But it's also Friday and it might
be a few days before one gets to reply. So, if you can wait, do that.

OK I just looked at the dmesg you attached, and you might have found a bug.
1.
Try -o ro,nologreplay because it's safe, and you can update your
backups if needed.
2.
If ro,nologreplay doesn't work, use 'btrfs restore' to extract
important files. The point here is to be prepared to lose the file
system before it's actually lost.
3.
Try to mount normally (no mount options) with a different kernel. If
it were me I would try in order:
5.0.0-rc6
4.19.23
4.14.101
4. If none of those kernels will mount it normally, wait if you can.
But once you need to move on you can try to zero the log as described
and then try a normal mount. If mount still fails but with different
messages, report back. It might be possible once zero log is run, to
use a backup root, or do a check using a specific root tree. But if
you're at this point, it's close to check --repair time and that can
sometimes make things worse.

So there is just some minor problem in fs trees, not a big problem, and
your extent tree passes the check, so it's not on-disk data corruption.

It's log recovery causing problem.
You could just use "btrfs rescue zero-log" to recovery it.

Thanks a lot for your help.
@Qu Wenruo: WIll zero log after completing the backup
@Chris Murphy: First of all, mount -ro,nologreplay works.
dump-tree displays two items:

Regards 2nd mail:
1. as mentioned, mount with nologreplay works. Will update backups with that.
2. Used btrfs restore already for initial backup. Did a good job.
3. Have to figure out how to get a usb-bootable recovery system w/ 5.0rc6 first.

Tried zero-log. After reboot the system booted again. But all
sub-volumes are mounted read-only.
This should be the relevant dmesg excerpt (note to last lines, there
it mentions forced to ro mode)

Some more important insights: The switch to read-only mode may not
only happen on boot but also during working. I got the system running
and then tried again to compile our project with IntelliJ. Result is
basically the same as described in 1st mail. Compile aborts with some
unclear error. But when looking at the mounted partitions, the btrfs
mounts have changed from rw to ro. I guess this is why initially there
were logs that could be wiped with zero-log. But the actual problem
seems to be somewhere else.
The relevant dmesg output is identical to the one in my previous mail
(see bottom of this mail).
As I have a backup of all data I tried some scrub and check --repair cycles:
First check --repair complained about two things:
* space and super gen don't match, space cache will be invalidated
* 2x deleting bad dir index
Second (or any repeated) check --repair (after a scrub):
* block group X has wrong amount of free space
* free space cache has more free space then block item group item,
this could lead to serious corruption, please contact btrfs developers
:)
* failed to load free space cache
Also tried mounting with clear_cache, but after a while the system
goes to RO mode again.
As mentioned, I should have a backup to recover from (at least I can
boot from it). So you can either advise me to do even more adventurous
things or just to give up and recreate the FS. If it's the latter: I
have not backed up /var/lib/docker/btrfs as this will simply explode
in size (due to snapshotting and me using rsync for backup). Losing
this dir is no big deal, I'd just be interested if there are better
alternatives for backup (e.g. https://github.com/mwilck/btrfs-clone).
Thanks in advance!
Here is the dmesg output of the error again:
