Hi Lev,
Nope, that doesn't work, as far as I can tell.
You'd have to revert to editting /etc/exports.
Or hack on 'zfs set sharenfs' to generate multiple lines, in some sort
of format. Like making ';' a line separator, and then prefix each part
with the volume we are modifying.
Place to give it a go are in:
cddl/compat/opensolaris/misc/fsshare.c:213
if (share) {
fprintf(newfd, "%s\t%s\n", mountpoint,
translate_opts(shareopts));
}
And there split the shareopts on the split char (eg. ';') in several
shareopts and then loop over them. Disadvantage is that the max length
op the options is: MAXPATHLEN. So you can easily run out of space if you
have many exports to do.
