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
