Hi,
I just found my btrfs filesystem to be remounted read-only with the
stacktrace below. (Similar experience to 87d0oyw46b.fsf@lausen.nl
earlier this year). Similar to <20191018025604.GA31526@merlins.org>, I
experience the following stacktrace following a suspend / resume cycle.
The system runs Linux 5.3.8 (unlike 5.1.21 in the previous report),
suggesting that the bug is around for a few months already.
Prior to suspension, I ran several compilation jobs. They all finished
without error.
You may find the output of
sudo btrfs inspect dump-tree -t root
and
sudo btrfs inspect dump-super
at http://termbin.com/ddxq and http://termbin.com/4mqt
The stacktrace is pasted below at the complete dmesg output at http://termbin.com/kr2j
As the bug affects the root partition, I suspect I won't be able to
boot the system after turning it off. Thus I leave it running for now
and can provide you with further information if so instructed.
Please also let me know if you suspect any chance to repair this
filesystem.
Best regards
Leonard

It seems this bug is indeed similar to <20191018025604.GA31526@merlins.org>.
Running
btrfs check --readonly /dev/$NAME
runs out of 16GB of memory within 20 seconds and is killed by the
kernel.
No errors are displayed and the only output is
[1/7] checking root items
[2/7] checking extents
btrfs check does not seem to contain a verbose mode? Is there anything
you would like me to do to help debug btrfs check, if not help debug the
root cause of this bug in the first place?
Please let me know.
Best regards
Leonard

Thank you for pointing this out Qu.
btrfs check --mode=lowmem finds
checksum verify failed on 1383731085312 found 000000CC wanted FFFFFFF5
checksum verify failed on 1383731085312 found 000000CC wanted FFFFFFF5
bad tree block 1383731085312, bytenr mismatch, want=1383731085312, have=15281531241332003907
ERROR: shared extent 1776065458176 referencer lost (parent: 1383731085312)
ERROR: errors found in extent allocation tree or chunk allocation
When creating a backup of the home directory after the filesystem was
mounted ro, only a single log file could not be included in the backup
due to failure to read it.
Is there any way to fix the filesystem, given that btrfs check
--mode=lowmem does not support --repair?
Do you think this corruption is related to some kernel bug, triggered
during suspend / resume cycle? Or could it be simply a harddrive (SSD)
failure? (An extended disk self test did not report any errors though.)
Best regards
Leonard
