Hello,
I have an external HDD. The HDD contains no partition.
I use the whole HDD as a LUKS container. Inside that LUKS is a btrfs.
It's used to store some media files.
The HDD was hooked up to a Raspberry Pi running up-to-date Arch Linux
to play music from the drive.
After disconnecting the drive from the Pi and connecting it to my laptop
again, I couldn't mount it anymore. If I read the dmesg right, it now
thinks that it's part of a raid6.
btrfs check --repair also didn't help.
```

It's not thinking it's a raid6 array. All the messages before this one:
Btrfs loaded, crc32c=crc32c-intel
Are completely unrelated to BTRFS (because anything before that message
happened before any BTRFS code ran). The raid6 messages are actually
from the startup code for the kernel's generic parity RAID implementation.
These:
BTRFS error (device dm-1): bad tree block start 9385453728028469028
1082114048
BTRFS error (device dm-1): bad tree block start 2365503423870651471
1082114048
Are the relevant error messages. Unfortunately, I don't really know
what's wrong in this case though. Hopefully one of the developers will
have some further insight.

Don't panic, the raid6 module is always loaded by btrfs, no matter if
btrfs uses or not.

Normally you shouldn't try it anyway.

This means, both copies for logical bytenr 1082114048 are corrupted.

You shouldn't really use --repair here.
Your extent tree is corrupted, --repair could make things worse here.

This is the root cause:
[ 124.544439] BTRFS error (device dm-1): bad tree block start
9385453728028469028 1082114048
[ 124.555229] BTRFS error (device dm-1): bad tree block start
2365503423870651471 1082114048
[ 124.555275] BTRFS warning (device dm-1): failed to read fs tree: -5
Your fs tree is corrupted.
I'm not sure how it's corrupted, but corruption to fs tree is a little rare.
Is there anything like unexpected power loss happens?
And would you provide the following data for debugging?
# btrfs ins dump-super -fFa /dev/mapper/black
And further more, what's the device mapper setup for /dev/mapper/black?
Is there anything like RAID here?
Thanks,
Qu

Hey,
Thanks for the quick reply :-)
> Is there anything like unexpected power loss happens?
Power loos may have happened. It was power via a RPi.
> And would you provide the following data for debugging?
>

See attachment.

> Is there anything like RAID here?
This is due to LUKS I think. "black" is the name I gave to cryptsetup open.

Hey,
Thanks for the quick reply :-)

>

I attached it.
> And further more, what's the device mapper setup for /dev/mapper/black?
> Is there anything like RAID here?
I think this is the result of luks. "black" is the name I passed to

No log_root* in the super. So no fsyncing at the time? What was
happening at the time of the power loss?
Pretty weird, all three supers are OK and yet two copies of the fs
tree are corrupt. Why doesn't it fall back automatically to one of the
other roots?
You could try 'mount -o usebackuproot,ro' and see if that's permissive
enough to succeed.
I wonder if the drive firmware reordered things contrary to Btrfs
expectation right at the powerfail - or even if the powerfail caused
the drive firmware to do the writes in the wrong order?

That I don't know.

That yields the same result
```
marble@archlinux ~ % sudo mount -o usebackuproot,ro /dev/mapper/black
/tmp/black
mount: /tmp/black: can't read superblock on /dev/mapper/black.

Looks pretty good.
Then we could go through normal salvage routine.
Please try the following commands and especially keep an eye on the
stderr output:
(The follow option is added in recent btrfs-progs releases, so please
ensure your btrfs-progs is up to date)
# btrfs ins dump-tree -b 1084653568 --follow /dev/mapper/black
# btrfs ins dump-tree -b 1083604992 --follow /dev/mapper/black
# btrfs ins dump-tree -b 1083981824 --follow /dev/mapper/black
# btrfs ins dump-tree -b 1084325888 --follow /dev/mapper/black
Or just use old roots and let btrfs check to judge:
# btrfs check --tree-root 1084751872 /dev/mapper/black
# btrfs check --tree-root 1083801600 /dev/mapper/black
# btrfs check --tree-root 1084145664 /dev/mapper/black
# btrfs check --tree-root 1084473344 /dev/mapper/black
>> And further more, what's the device mapper setup for /dev/mapper/black?

Maybe some powerloss screwed up encryption?
I'm not pretty sure how things will happen when power loss happens.
Anyway, let's see how above btrfs check and dump-tree ends.
Thanks,
