What messages appear in dmesg and coincide with the failed command?

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 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 ?
