Hi,

since I updated my system I noticed a lot of messages like the following
in dmesg (sda8 is /home).

BTRFS critical (device sda8): corrupt leaf: root=1 block=78397440
slot=32, invalid root item size, have 239 expect 439

I did a 'btrfs scrub' but it didn't find any errors. Then I started the
system in single user mode and tried 'btrfs check' but again, no error
could be found.

I read that the issue could come from bad RAM and so I ran memtest86+
for 12h but it seems my RAM is ok.

Is this a real problem and how can I fix it?

Thanks a lot,
Matthias

Scrub compares block contents with its checksum, if there's a match,
no error is reported. But the contents of the leaf might not be valid,
with the leaf's checksum based on that corruption. In recent kernels
there's a tree checker that does a validation check.

The tree checker code is what you've hit, and it's saying there's a
problem with the leaf contents. Depending on the update you did, it's
possible that this is corrupt leaf has been there for a while, and is
only just now showing up with the newish tree checker code, in 5.2 and
5.3 kernels.

Could be the result of a Btrfs bug in an older kernel, and it's only
now being caught because of the tree checker.

Good question. The kernel message is very convincing, in that it
suggests it knows exactly what the problem is and what the expected
value should be. I'd like to believe 'btrfs check' could fix it.

What do you get for:

btrfs insp dump-t -b 78397440 /dev/

If there are filenames in the output you can remove/sanitize them.

btrfs check /dev/

This should give a good idea whether --repair can fix it, but we'll
need to hear from a developer about it first. In the meantime you can
make sure the backup is current.

Ah, ok.

These strange filenames are cache files from firefox and so I just deleted them. But if I put in other block numbers which appear in dmesg for dump-t I am not so lucky:

This is a node. It points to leafs. So what we're looking for depends
on the exact kernel error that you got the block number from.

So btrfs check has no errors but you're still seeing corruption
messages from the kernel? What about using check with the
--mode=lowmem option? It's a lot slower.

If it's not causing grief yet, I'd give it a few days for a developer
to reply about what might be going on. And whether it can be fixed.

But yes, this is metadata corruption. So a new file system won't have
the problem.

Ah, ok. So when I do a

# btrfs insp dump-t -b 285405184 --follow /dev/sda8

I get quite a lengthy output with leafes (and filenames) in it (see attachment).
The last line is

ERROR: child eb corrupted: parent bytenr=285405184 item=13 parent level=1 child level=1

I give you an idea how the errors appear in journalctl:

The difference in root item size seems to be the same all the time ("have 239 expect 439").

Exactly. This is the output when running the check with lowmem:

[1/7] checking root items
[2/7] checking extents
[3/7] checking free space cache
[4/7] checking fs roots
[5/7] checking only csums items (without verifying data)
[6/7] checking root refs done with fs roots in lowmem mode, skipping
[7/7] checking quota groups skipped (not enabled on this FS)

I thought so, but was not completely sure. So I don't have a problem waiting a few days.
