As a 'stop' action ensure the filesystem is unshared before it is unmounted, just in case. Additionally, export the pool so it may be cleanly imported by a different host. Signed-off-by: Turbo Fredriksson <turbo@bayour.com> Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #2003

# description: This script will mount/umount the zfs filesystems during

# should be mounted is handled by the zfs 'mountpoint' and
|
|
# 'canmount' properties. See the zfs(8) man page for details.

# It is also responsible for all userspace zfs services.
