I'm running my normal workstation with git kernels from
git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-testing.git
and just got the second file system corruption in three weeks. I do not
have issues with stable kernels, and just want to give you a heads up
that there might be something seriously broken in current development
kernels.
The first corruption was with a kernel based on 4.18.0-rc1
(wt-2018-06-20) and the second one today based on 4.18.0-rc4
(wt-2018-07-09).
The first corruption definitely destroyed data, the second one has not
been looked at all, yet.
After the reinstall I did run some scrubs, the last working one one week
ago.
Of course this could be unrelated to the development kernels or even
btrfs, but two corruptions within weeks after years without problems is
very suspect.
And since btrfs also allowed to read corrupted data (with a stable
ubuntu kernel, see below for more details) it looks like this is indeed
an issue in btrfs, correct?
Not in newer kernel anymore.
Btrfs kernel module will do *restrict* check on tree blocks.
So anything unexpected (or doesn't follow btrfs on-disk format) will be
rejected by btrfs module.
To avoid further corrupting the whole btrfs.
Not sure I can follow that. Shouldn't I get a read error for a file due
to checksum mismatch if btrfs did not write it out itself?
I could copy the complete git tree without any noticeable errors.
A btrfs subvolume is used as the rootfs on a "Samsung SSD 850 EVO mSATA
1TB" and I'm running Gentoo ~amd64 on a Thinkpad W530. Discard is
enabled as mount option and there were roughly 5 other subvolumes.
I'm currently backing up the full btrfs partition after the second
corruption which announced itself with the following log entries:
[ 979.223767] BTRFS critical (device sdc2): corrupt leaf: root=2
block=1029783552 slot=1, unexpected item end, have 16161 expect 16250
This shows enough info of what's going wrong.
Items overlaps or has holes in extent tree.
Please dump the tree block by using the following command:
# btrfs inspect dump-tree -b 1029783552 /dev/sdc2
# btrfs inspect dump-tree -b 1029783552 /dev/sdc2

And please run "btrfs check" on the filesystem to show any other problems.
(I assume there will be more problem than our expectation)
Compared to the first crash this looks harmless:

I'll restore the system from a backup - and stick to stable kernels for
now - after that, but if needed I can of course also restore the
partition backup to another disk for testing.
Since it is your fs corrupted, using older kernel ignores such problem
is not the long term solution in my opinion.
I agree. I just want to verify it's indeed stable again.
It may well be some no kernel issue at all and just bad timing with some
HW breakdown.
Here what I can say from the first crash:
On Jul 4th I discovered severe file system corruptions and when booting
with init=/bin/bash even tools like parted failed with some report about
invalid ELF headers for some library. I started an Ubuntu 17.10 install
on another physical disk and copied some data from the damaged btrfs
volume to the Ubuntu disk. And while I COULD copy the files quite many
of the interesting ones were broken:
e.g. the git tree I rescued from the broken btrfs disk is unusable. The
broken files I found all look about the correct size but contain only 0x01:
$ hexdump -C .git/objects/9d/732f6506e4cecd6d2b50c5008f9d1255198c1e
00000000 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01
|................|

After copying the files I tried a "btrfs check --repair" which was
finding countless errors and I aborted after I got more than 3 million
lines output.
--repair should never be your first try by all means.
And in fact, sometimes it could even further corrupt the fs.
Ups, I just notice I have called it with --repair again. At least this
time I have a backup and can restore to the old state....
I was aware of that the first time but lazy.
Problem was, that many basic system binaries were broken and it looked
like repairing it was more work than starting over from scratch.
I was already set on reinstalling and just kind of wanted to see what
happens.
Greetings,
Alexander
