Hi,
I need some advice on a btrfs raid-1 volume that shows a few corruptions
on some places. I have some files that triggered some safeguards on
write, which ended up remounting the fs as read-only.
Over on IRC, multicore suggested me to run a readonly check, whose
output is here:
# btrfs check --readonly
/dev/disk/by-uuid/e944a837-f89b-48ea-80fd-40b2bec8f21b

They suggested that I run a non-ro check, but warned that it could do
more harm than good, hence this email seeking advice. Has check any
chance to fix the issue?
I think I should also mention that I'm fine deleting those specific
files as I can get them back somewhat easily.
To finish off, here is the information requested by the wiki page:

The dmesg is attached to the email, but most of the `BTRFS critical` log
lines related to name corruption have been removed to get the file to 200KB.
Some things to note:
- I recently upgraded the machine from Debian 9 to 11, getting the
kernel from 4.9 to 5.10, but the issue already existed on 4.9 (it even
started there, prompting me to replace a drive as I though it to be the
source of the corruption).
- The kernel is almost the vanilla debian bullseye kernel, with an added
(tiny) patch to fix an issue between 3Ware RAID cards and AMD Ryzen
CPUs. It should not affect the BTRFS subsystem as it adds a quirk to the
PCIe subsystem.
- I have a few name mismatches, which can be seen in the logs too. While
I'd love someday to get rid of them, I simply moved the affected files
in a corner for now. That's not the issue I'm trying to solve now
(though if someone can help, I'd be glad). They come from a ZIP archive,
so deleting them is fine, but I can't as I only get "Input/Output error"
when trying to rm them.
Thank you very much to whoever can help!

This is one corruption in extent tree, we don't have root 23 at all.
Only root 7 is correct.
On the other hand, 23 = 0x17, while 7 = 0x07.
So, see a pattern here?
Thus recommend to memtest to make sure it's not a memory bitflip causing
the corruption in the first hand.

This can also be caused by memory bitfip.
Fortunately, both cases should be repairable.
But that should only be done after you have checked your memory.
You won't want to have unreliable memory which can definitely cause more
damage during repair.
But it's still better to keep important data backed up.

One thing to mention is, if you're running kernel newer than v5.11, the
last corruption (the one on name hash mismatch) can be detected early,
without writing the corrupted data back to disk.
Thus it's recommended to use newer kernel.

That definitely looks like a bitflip to me.

Yes, definitely a bitflip, f = 0x66 and v = 0x76.

Amazing advice. I'll definitely upgrade the kernel, likely latest.

Thank you very much to you! I just started a full memtest on the
machine. I expect it to be good, since the RAM is brand new (just
swapped the whole system due to the previous motherboard dying), but you
never know. I'll get back to you with the results!
Also, if I can get my hands on a DDR3 system, I'll test the old ram to
be sure. If this ends up being a RAM issue, I'll send back the current
one and buy some ECC memory.
Thanks,
Alexis

Hi,
It's me again. I have completed several memtest86+ passes without errors
whatsoever, so this RAM can be considered good. Also, following your
advice, I built and upgraded the kernel to the latest stable, i.e. 5.15.10.
What is the next step to (hopefully) fix the error? Is it to run `btrfs
check` but not in readonly mode. I think I'll need to upgrade
btrfs-progs too since I'm now running 5.15.10 instead of 5.10.70.
Thank you so much in advance!
Alexis

Yes, latest btrfs-progs is always recommended.
After backing up the important data and upgrading btrfs-progs, "btrfs
check --repair" could at least solve the extent tree problem.

Hi,
Thank you so much for your advice. The check in repair mode did indeed

I'm stressing a bit the drives right now to see if everything's solved,
but it looks like it.
Cheers!
Alexis

To be safe, another read-only btrfs-check would tell you if all the
