Actually I've just figured why I could not export the pool.
One of my docker containers was using the FS, so I could not see it with the "lsof" :/ (mount namespace). I figured when I saw multiple zfs kernel calls with bpftrace :-)

I am wondering what would be required for the "zfs unmount -a" to actually fail when its FS is actually used in some other namespace?
