The man page on stable/9, for me, says clearly:
Setting compression to on uses the lzjb compression algorithm.
This is as of r251935.
Your catman pages may be out of date. I deal with this problem per a
recommendation of dougb back in the day: "rm -fr /usr/share/man/*" right
before doing "make installworld". I've just gotten in the habit of
remembering to do it every time.
Otherwise render what's in /usr/src yourself:
nroff -Tman -man /usr/src/cddl/contrib/opensolaris/cmd/zfs/zfs.8 | less
