My raid6 fails to mount after a disk failure with unclean shutdown
From other posts I understand that if there is a still working chunk
root I could still get some data back
I have the really important data in backups, but most of my holiday
photos/videos are only on the array, so I'm happy about any partial
data that you could help me restore
I've listed below the output of what I've tried so far below
Hope you can help
Regards,
Alexander

Already missing one device, this means now raid6 can only tolerant one
device corruption.

This means the corruption happens at chunk tree, which is needed to
bootstrap and a very critical tree.
Could you get that missing device back and try again before trying any
other recovery?

If you want to use find-root, you at least need to use "-o 3" option.
That would be a pretty good start point.
Since chunk recovery doesn't work at all, your remaining recovery method
would be something like:
1. btrfs-find-root -o 3 /dev/sdc
Get the bytenr of possible chunk roots.
2. btrfs check --chunk-root <bytenr> /dev/sdc
To see if you can get pass the "Couldn't read chunk tree" error.
3. If you get a good chunk bytenr, either pass it to btrfs-restore or
modify superblocks to allow kernel to mount it.
Thanks,
