Also, there is one situation - not part of the original request - where the use of /etc/vfstab is not only preferable, it's required: NFS mounts. If a zone needs to mount an NFS share from a different system, the zone's administrator must perform the mount, either manually - from within the zone - or automatically, in the zone's /etc/vfstab. -- --JeffV ___ zones-discuss mailing list zones-discuss@opensolaris.org

Hi, why /etc/vfstab is not right solution for you ? We use it and it just works.

Within the fs resource, options are also a resource, so you do not use the 'set' command. Instead, you 'add' options. The syntax for the above example would look like this: zonecfg:lt203398:fs add options convosync=direct Jerry ___ zones-discuss mailing list zones-discuss@opensolaris.org
