Hello,
I need to clarify, I'm _not_ sharing a drive between multiple computers
at the _same_ time. It's a portable device which I use at different
locations with different computers. I just wanted to give a rationale
for mounting the whole drive to some mountpoint and then also part of
that drive (a subvolume) to the respective computer's /home mountpoint.
So it's controlled by the same kernel in the same computer, it's just
that part of the filesystem is mounted at multiple mountpoints, much
like a bind-mount, but I'm interested in mounting a subvolume of the
already-mounted volume to some other mountpoint. Sorry for the confusion.
Best regards
Sebastian

Hello,
I'm sharing a btrfs-formatted drive between multiple computers and each of the
machines has a separate home directory on that drive.
2+ computers writing to the same block device? I don't see how this is safe.
Seems possibly a bug that the 1st mount event isn't setting some metadata so
that another kernel instance knows not to allow another mount.
