Hi, this is your Linux kernel regression tracker speaking.

I noticed a regression report in bugzilla.kernel.org. As many (most?)
kernel developer don't keep an eye on it, I decided to forward it by
mail. Quoting from https://bugzilla.kernel.org/show_bug.cgi?id=216851 :

I am experiencing btrfs file system errors followed by a switch to
readony with kernel 6.1 and 6.1.1. It never happened with kernel
versions before.

A btrfs scrub and a btrfs check --readonly returned 0 errors.

There are no SSD access errors in the kernel logs. Smart data for
the SSD is normal. I also did a 12 hour memtest to rule out bad RAM.

The filesystem consists of a single 480GB SATA SSD (Corsair Neutron
XTI). The problems occurs only on one machine.

The error appears about every few days and seems to be triggered by
a cspecially under high cpu utilization combined with some disk IO.
CPU temperature never exceeds 60 degrees.

See the ticket for more details.

For the record, the issue is apparently different from the 6.2-rc
regression currently discussed, as stated here:
https://lore.kernel.org/lkml/462e7bd3-d1f2-3718-fde9-77b418e9fd91@xxxxxxx/

BTW, let me use this mail to also add the report to the list of tracked
regressions to ensure it's doesn't fall through the cracks:

#regzbot introduced: v6.0..v6.1
https://bugzilla.kernel.org/show_bug.cgi?id=216851
#regzbot title: btrfs: write time corrupting for log tree in 6.1
#regzbot ignore-activity

#regzbot fix: 'btrfs: fix false alert on bad tree level check'

Oh no, this is a different one, this one is not level mismatch.

Thanks,

Hi,

Here the logging from another crash, this time on kernel 6.1.3, about 1
hour after boot. Again during high CPU usage combined with lots of io.

the full thing.

I've previously commented on that in the other thread:

Hi,

here is the full message:

Ok, this is intriguing. Same set of keys is added twice to a leaf.

Are you able to apply a debug patch which adds extra logging when the
issue happens?
That would be the fastest way to figure where and why the issue is happening.

Thanks.

Sorry, I didn't notice your message in the other thread.

Thanks in advance,

Hi,

Yes, if you send me a debug patch, I can apply it. However it might take
between 1 hour and 2 weeks until the next crash.

That would be very helpful.
So here's a debug patch (against 6.2-rc, but should apply to 6.1 as
well) attached.

Thanks a lot!

Thanks in advance,

David Arendt

Hi,

The patch did not apply to 6.1.3, so I tried using 6.2-rc2. I did my
best to do much IO and different load as possible and was having this
output:

Wow, that was fast!

However this time the filesystem didn't switch to readonly.

Yes, the debug patch changed that too. It's actually not a critical
situation to turn the fs to readonly.

Ok, I see now what's going on. I will work on a fix for that plus a
few other things I noticed are not right.
I'll likely submit the changes to the list by monday or tuesday, and
let you know in case you want/can test them.

Ok, here they are:

https://lore.kernel.org/linux-btrfs/cover.1673361215.git.fdmanana@xxxxxxxx/

Thanks a lot for the testing and reporting.

Thanks in advance,

David Arendt

Hi,

Many thanks.

I have applied the patches to 6.2-rc3 and tried to do everything to reproduce the problem so the problem seems to be fixed by the patches, but for sure only time will tell.

Bye,

David Arendt

Hi,

In 6.2-rc3 + your patches, the problem did not appear within 2 weeks. I skipped rc4 and today I upgraded to 6.2-rc5 which should have to patches included (or not ?). About one hour later, the filesystem turned again read-only with the following kernel log entries:
