Hello Hugo,

thanks for your information.

I have an 1 TB BTRFS-Partition which suddenly could not be mounted.

I tried the following commands


host@:btrfs check -b /dev/mapper/vg0-virtualbox
....
Errors found in extent allocation tree or chunk allocation
bytenr mismatch, want=1263661723648, have=0




host@:btrfs rescue super-recover -y  /dev/mapper/vg0-virtualbox
All supers are valid, no need to recover


Then i did
btrfs rescue chunk-recover -y  /dev/mapper/vg0-virtualbox
This commands fails after around 2.5 hours with the messages, that it
could not recover the chunc tree.

What are the next possibilities?

Greetings,

Michael
