A follow-on question. If the zvol (virtual disks) are mounted READ ONLY, is it possible to mount it on multiple FreeBSD systems at the same time and access it for reading only from all the systems? (With only one system having it R/W and that only being used occasionally when the new software needs to be installed for the jails)? What I want to do does not rely on this but could make things easier for me... _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
