More stranges (different system with the same src):

[root at fujic ~]# mount | grep vol0
/dev/ad0s2d on /vol0 (ufs, local, soft-updates)
[root at fujic ~]# mount -u -o ro /vol0
[root at fujic ~]# mount | grep vol0
/dev/ad0s2d on /vol0 (ufs, local, soft-updates)
[root at fujic ~]# mount -u -r /vol0
[root at fujic ~]# mount | grep vol0
/dev/ad0s2d on /vol0 (ufs, local, read-only, soft-updates)
[root at fujic ~]# mount -u -o rw /vol0
[root at fujic ~]# mount | grep vol0
/dev/ad0s2d on /vol0 (ufs, local, soft-updates)

So "mount -u -o ro" doesn't work but "mount -u -o rw" does.
