Hi,
today after waking my PC up fom suspend it was totally frozen up, so I reset the machine. Now I get the message "error on < uuid-of-caching-device>: corrupted btree at bucket 4067, block 389, 514 keys, disabling caching and iam thrown into emergency mode.
I can force bcache to start but it won't mount. The cache state of my backing device is shown as "inconsistent" even after flushing the cache to the backing device.
I reformatted and reattached the caching device
“btrfs device scan” won't recognize it either. -> it does now
If i try to mount the filesystem i get an error (see mount -a).
Trying to run fsck on it first spits out a lot of errors like this "btrfs parent transid verify failed" and then causes fsck to segfault.
This partition holds my /home and i just recently deleted my backups(stupid, i know) as my sister needed the drive.
How can i get this back to work?

I actually have the very same issue today, on my Laptop with a samsung 960 240 G drive. BTRFS holds my /home and is unmountable.
The exact error is "parent transid verify failed" and shows the difference in blocks.
Partition is unmountable. Was working a-ok until it shutoff itself during sleeping due to the lack of no power connected.
Anyone in the community experienced this?
A set of errors I run into while running btrfsck --repair on the partition, namely:
- Ignoring Transid failure,
- Errors in allocation tree or chunk allocation
- bad blocks
- leaf parent key incorrect
- a list of errors wrt to the transid failure
It seems that after losing power in sleep, the partition is fucked.
Thats a huge, huge huge issue. Can this be repeated?

I invented EM Field Patterns and fixed Feynmann's Diagrams so they are physical.
