Hi there,

Since today, my system started randomly becoming read-only. At that 
point I can still run dmesg in an open terminal, so I’ve seen it was 
related to a btrfs error, but did not try anything since I could not 
open a web browser anymore. But I’ve seen the error to be “BTRFS 
critical” and related to a “corrupt leaf”.

I’ve tried to run `btrfs scrub` on the device after rebooting, and in 
fact it aborted almost right away triggering the same error in dmesg 
(but not turning the system read-only, so I can copy paste it here):

[  365.268769] BTRFS info (device dm-0): scrub: started on devid 1

According to https://btrfs.readthedocs.io/en/latest/Tree-checker.html 
this is not really expected, and the last paragraph says to report 
troubles here. So here I am, in the search for advice about this error 
(web searches returned nothing with this specific error except the 
commit/ml messages that added the code for it) and how to fix my random 
lockups.

Full dmesg please.

Normally it should dump the full content of the tree block, to help
debugging the problem.

Thanks,

Nevermind, the code doesn't dump the full leaf for debug anyway.

In that case please dump that corrupted leaf by:

  # btrfs ins dump-tree -b 1182031872 /dev/dm-0

Sorry for the delay, in the meantime my computer went unbootable: the 
initramfs went missing, then some systemd files… Last time such things 
happened was when my btrfs went out of free space, but there is plenty 
currently, so I guess this is related to this other kind of btrfs issue 
I’m facing. Now everything seems in order and I’m back to my emails.

Here is the output of the asked command:

# btrfs ins dump-tree -b 1182031872 /dev/dm-0
btrfs-progs v6.10.1
checksum verify failed on 1182031872 wanted 0x00000000 found 0x21b9544e
ERROR: failed to read tree block 1182031872

Some additional informations:

1. I was able to save the log the next time it went read-only, it is a 
bit different:

[ 4588.750188] page: refcount:4 mapcount:0 mapping:00000000d0054cae

2. I’ve thus decided to run

# btrfs ins dump-tree -b 11287011328 /dev/dm-0
btrfs-progs v6.10.1
checksum verify failed on 11287011328 wanted 0x00000000 found 0x2c7de3ac

and

# btrfs ins dump-tree -b 11285897216 /dev/dm-0
btrfs-progs v6.10.1
checksum verify failed on 11285897216 wanted 0x28b52ffd found 0xa166b670
ERROR: failed to read tree block 11285897216

3. There is some information on kernel loading

[   12.793025] Btrfs loaded, zoned=yes, fsverity=yes
[   12.886212] BTRFS: device label root devid 1 transid 6065022

(Especially the “corrupt 4” I guess, but the warning above might also be 
relevant?)

4. I’ve run a full scrub while the disk was mounted on another system, 
which returned no error.

5. I’ve also run a check from that system while the fs was not mounted:

# btrfs check /dev/mapper/rootext

This looks exactly like another report that is caused by inode cache.

So in that case, mind to try the following commands?

# btrfs rescue zero-log <device>
# btrfs rescue clear-inode-cache <device>

Then try mounting the fs.

I supposed the second command was meant to be `clear-ino-cache` (I 
remember having to remove `inode_cache` from mount options some time ago 
as it prevented booting, I had then discovered the related feature had 
been deprecated and removed).

Here are the command outputs:

# btrfs rescue zero-log /dev/mapper/rootext
Clearing log on /dev/mapper/rootext, previous log_root 0, level 0

# btrfs rescue clear-ino-cache /dev/mapper/rootext

That being said no critical error has been encountered since I’ve had to 
repair my boot, but I’ve not tried to scrub from the running system 
again, should I do that (as it used to trigger the error before)?

Please do a `btrfs check` to make sure everything is fine.

For the bad free space cache, I'd recommend to go v2 space cache instead.

While the previous one (see my second message in this thread) had no 
error, there is now one:

Since the above error seems related to space cache, and that I had 
switching to v2 on my todo list for a long time, I’ve just did so.

dmesg mount messages right after (nothing unexpected I guess, outside 
the warning and “corrupt 4” still present):

I’ve run check again after that:

So there is still an error, but different this time.

Minor problem, still I'd recommend to run
  `btrfs rescue clear-space-cache v1 <dev>` to clear the v1 cache first.

Then you can mount with v2 space cache or keep going with the v1 cache
(not recommended, will be deprecated soon)

And if your fs only have subvolumes 5 (the top level one), 257 and 258,
then you're totally fine to continue.
I guess that's the case?

If you have other subvolumes, then you may need to wait for my fix to
ino-clear code to clear the remaining subvolumes, just in case.

Thanks,
Qu

I indeed did that as explained in the second part of my message.

Done too.

Indeed!

Just in case, you can run "btrfs check --mode=lowmem" to check if there
is no more inode cache left.

If there is any left, lowmem mode can detect it with errors like:

ERROR: root 5 INODE[18446744073709551604] nlink(1) not equal to
inode_refs(0)
ERROR: invalid imode mode bits: 00
ERROR: invalid inode generation 18446744073709551604 or transid 1 for
ino 18446744073709551605, expect [0, 72)
ERROR: root 5 INODE[18446744073709551605] is orphan item

And I'm already adding the ability to the original mode check to detect
such problem.

Thanks,
Qu

No such thing appeared during the lowmem check. Only the

Then it's totally fine.

For the 0-65536 problem, mind to provide the following dump?

# btrfs ins dump-tree -t fst <device>

I'm afraid since the fs is somewhat old, there may be some corner case 
btrfs-check is not handling properly.

My bad, it should be "btrfs ins dump-tree -t free-space <device>".

And if possible, also "btrfs ins dump-tree -t extent <device>" just in case.

The output is too big for an email, so uploaded here:

https://paste.xinu.at/XtR8/

Same thing (even bigger), also output on the terminal and while 
redirecting to a file was quite different (but maybe that’s more because 
something changed between the two calls), so here are:

– the cli run : https://paste.xinu.at/9vs/

– the file run: https://paste.xinu.at/XpzhbZ/

Thanks a lot.

This indeed shows a very old filesystem, and for a long long time, we no 
longer create any block group at logical bytenr 0, thus it shows an 
corner case that older fs layout doesn't exclude the first 1MiB.

And it's indeed a false alert.

In that case, as long as you still have unallocated space, you can just 
relocate the system chunks:

# btrfs balacne start -s <mnt>

Which should move the system chunks to new locations and will not 
utilize the first 1MiB reserved space.

Qu

IIRC this file system was created in 2016.

# btrfs balance start -s /
ERROR: Refusing to explicitly operate on system chunks.
Pass --force if you really want to do that.

According to https://btrfs.readthedocs.io/en/latest/btrfs-balance.html, 
-s requires -f, so I guess I should continue with that?

That explains why the first chunk starts at exactly bytenr 0.

Newer fs will start at bytenr 1M, so it won't touch the reserved range.

Yes.

And I also recommend to convert your metadata and system chunks to DUP,
if there are enough unallocated space.
(If have more devices then RAID1).

It looks like the old mkfs defaults to SINGLE for SSDs, but nowadays we
keep DUP no matter if it's SSD or not.

Hum, no success:

# btrfs balance start -s --force /
ERROR: error during balancing '/': No space left on device
There may be more info in syslog - try dmesg | tail

Indeed,

Alright, but I guess I need to solve -ENOSPC first…

OK, ramping usage until something was moved did the trick.

Thanks again for your help,

This means most of the "free" space is inside data chunks.

You will need to free up some continuous data space, or use different 
"usage=" filters for data and metadata, or both.

Thankfully your metadata has enough free space, so not an urgent situation.
