Hi,
I recently started a balance on a BTRFS filesystem.
At least one process failed to write files before or during the
balance due to a supposed out-of-space condition.
Yes, I know it's not good to allow that to happen.
Here is the relevant dmesg output:
[694828.101677] BTRFS info (device sdh1): balance: start -dusage=60
[694828.103543] BTRFS info (device sdh1): relocating block group
2933242462208 flags data
[694883.648385] BTRFS info (device sdh1): found 76 extents
At that point, disk I/O according to iotop dropped to almost zero.
After waiting a while, I attempted to cancel the balance, but that
just resulted in a hung cancel process.
Now, any process that attempts to write to or read from the filesystem hangs.
I suppose that means there's a kernel deadlock.
The output of dmesg after running echo w >/proc/sysrq-trigger is attached.
kernel: 5.0.3-arch1-1-ARCH x86_64
btrfs-progs version: v4.20.2
The data that was being written to the filesystem is not important.

Yes, I have qgroups enabled on that filesystem. I'll disable qgroups
the next chance I get, they aren't worth the trouble.
After rebooting, BTRFS finished the balance. I then foolishly started
a selective metadata balance, which never got past the first block
group; it just thrashed the disk for several hours.
It could not be canceled, so I rebooted.
Then I mounted the filesystem with skip_balance and clear_cache.
The mount failed. The relevant part of dmesg is attached.
That looks pretty bad. Unfortunately, I don't have any backups of
this filesystem, though before this I was planning to purchase some
disks for that purpose.

I can't parse that, maybe Qu has an idea. In the meantime I suggest
btrfs-progs 4.20.2 and running:
# btrfs check --readonly /dev/
Attach that output.
Balance is supposed to be COW. And skip_balance and clear_cache are
supposed to be safe. So I'd say you've found a bug but I don't know
what it is or how to work around it.

What do you get for:
# btrfs insp dump-s -f /dev/
# btrfs insp dump-t -b 2629033574400 /dev/
The csum test doesn't complain so that suggests any corruption happens
before csum is calculated and written. It could be a bug, however we
also have a wanted transid that is lower than what's found (finds a
transid in the future). That's a bug no matter what, either the drive
firmware has some bug or Btrfs, and I would expect the firmware can't
be responsible for such a huge transid difference. But yeah maybe Qu
has an idea, also he knows about qgroups, I don't know anything about
them other than it can make things very slow. There are some fixes on
the way soon but it doesn't really help today.

Unfortunately, your fs indeed get corrupted, but only in extent tree.
You should be able to mount the fs in RO mode and copy out the data.
But I'm surprised that balance by somehow corrupted the metadata CoW.
Would you mind to paste the output of the following command?
# btrfs ins dump-super /dev/sdh1
# btrfs ins dump-tree -b 2629033574400 /dev/sdh1
If the output of the 2nd command contains filenames, feel free to remove
filenames.
I'm just interested in which tree btrfs is trying to write into existing
tree blocks, maybe it has some clue (e.g log tree/reloc tree).
Thanks,
Qu
