What messages appear in dmesg and coincide with the failed command?
Absolutely nothing is added into the dmesg:
I haven't heard of anyone being unable to delete snapshots before. But
also suspicious about this particular snapshot (which I also haven't
ever seen) is its generation is 0. Even brand new subvolumes on a
brand new file system have non-zero generation.
Any way I can forcefully remove it ?
I can use `rm -rf` on the actual directory but the entry still shows up when I do :
btrfs sudo subvolume list /
> This is even weirder since as you can clearly see the directory exists in the given path.
>
> Any suggestions on what is going wrong ?
>
> I should tell you that a while back I had a huge BTRFS file system crash, and it took a lot of targeted help from the community to get my system to boot.
This could be a side effect of an incomplete repair.
It probably is, so is there anything that can be done, other than a full reinstall ?
