You surely can set the readonly attribute for a ZFS fs on a read-only 
mounted zpool. Mounting the zpool readonly only seems to affect the 
global setting. It seems to possible to change the ZFS FS attributes 
without any issue. So the work around was…

zpool import -o ro zpool
zfs set readonly=on zpool/zfs
zpool export zpool
zpool import zpool
zfs set readonly=off zpool/zfs

This has always worked for me and it still does.
