Description David Van Cleef 2007-05-31 06:50:03 UTC 
	
If a heirarchy of nfsshared ZFS filesystems exists, and a non-leaf filesystem
has its nfsshare property changed, the children have their zfs property properly
changed, however the current nfs export-state is not changed for the children.

How-To-Repeat: 	
# zfs create -o sharenfs="node1" tank/exports/top
# zfs create tank/exports/top/bottom
# showmount -e localhost
/tank/exports/top/bottom	node1
/tank/exports/top		node1
# zfs set sharenfs="node2" tank/exports/top
# showmount -e localhost
/tank/exports/top/bottom	node1
/tank/exports/top		node2
# zfs get sharenfs tank/exports/top
NAME           PROPERTY  VALUE                        SOURCE
tank/exports/top  sharenfs  node2  local
# zfs get sharenfs tank/exports/top/bottom
NAME                PROPERTY  VALUE                        SOURCE
tank/exports/top/bottom  sharenfs  node2  inherited from tank/exports/top

Reassign to Pawel since this appears to be affecting ZFS. 
Pawel can you have a look at this please?

With pjd's permission, reassing ZFS-related PRs to freebsd-fs.

The problem you described was related to buggy detection of shared file 
systems which I just fixed. With this fix I'm not able to reproduce your 
problem, sharenfs property on parent changes children too as confirmed 
with 'showmount -e'. Thanks for the report!
