thanks,
Sorry for the late reply.

It's so slow, no matter the mode I'm using.
So I'm not sure if it's a deadlock since lowmem mode still takes
several minuts and ju

It only contains the basic block group info.

Not sure, but lowmem is high IO.

So, it just avoids any possible dead loop AFAIK.

You could try to use --mode lowmem, which doesn't ever use any loop to
get next block, but iterating trees.
Current in mainline btrfs-progs, the low memory mode code only checks
extent/chunk trees, file/subvolume trees are still checked by original mode.
You could try the devel branch from Da
