Description
Hi,
I'm unable to mount any BTRFS filesystem. I get "General system error" when trying to mount them via Tracker and "mount: No such file or directory" when trying via the command line. I get the following error in the syslog:
KERN: ahci: sg_memcpy phyAddr 0x9f35680, size 8 KERN: btrfs: Find() unmapped block 0 Last message repeated 1 time KERN: btrfs: Volume::Mount(): Couldn't find extent root KERN: btrfs: Failed mounting the volume. Error: No such file or directory

Can you provide the outputs of the two following commands with argument is your device ? (run as root if neccessary)
btrfs-show-super -f your_device btrfs-debug-tree your_device
if your linux system doesn't provide it by default, you can download it or compile it from here
The new version of btrfs tools just change the command lines, so you can try it with these
btrfs inspect-internal dump-super -f your_device btrfs inspect-internal dump-tree your_device

I'll upload tree dumps to another server and link them later, because they take a lot of disk space. I have one more partition (sda3) - trying to mount it crashes the system - https://i.imgur.com/rON897U.jpg Should I report it as a separate issue or provide outputs for this partition too?

Replying to Przemysław Buczkowski:
I'll upload tree dumps to another server and link them later, because they take a lot of disk space.
If it takes too large, you can truncate part of it or only print the info of root tree and chunk tree (btrfs-debug-tree -t1 your_device, and -t3)
I have one more partition (sda3) - trying to mount it crashes the system - https://i.imgur.com/rON897U.jpg Should I report it as a separate issue or provide outputs for this partition too?
I think make it as a separate issue is better because this is different cause.
