Hello
In http://review.gluster.com/8649 I attempt to emulate lazy umount on
systems that lacks this Linux-only feature. I do this by spawning a
thread that periodically attempt to umount and then rmdir the mount
point.
That works nicely for some scenario (it lets NetBSD pass
tests/basic/pump.t),

Emmanuel,
Yeah, that should do. I don't think you need
to go out of the way to support lazy umount functionality
in *BSD, when it's not essential to the working of replace-brick
and other commands that use lazy umount.

Emmanuel,
IIRC, lazy umount is being used in glusterd to avoid leaving
behind an entry in /etc/mtab, for every internal mount that
failed to unmount for some reason. replace-brick command doesn't
have a requirement that the umount must happen in a lazy manner.
HTH,

Hi
Lazy umount is a Linux-only feature that let userland tell the kernel to
umount a filesystem as soon as it drops the last reference to it. It is
used at a few places by GlusterFS and is a portability problem.
brick-replace will not currently work without it, which is a critical
problem.
