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 Your catman pages may be out of date.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 -- | Jeremy Chadwick jdc@koitsu.org | | UNIX Systems Administrator http://jdc.koitsu.org/ | | Making life hard for others since 1977.
