HA-Samba has been available for 4+ years. Sharing the file systems is the easy part. Reconciling locks is the hard part. iSCSI has very limited locking capabilities (reservations). For CIFS, the existence of HA-Samba agents sets a precedent. The HA Samba agent is written in ksh, so it shouldn't be too scary :-) http://opensolaris.org/os/community/ha-clusters/ohac/Documentation/Agents/open-agents/ Or, if you want to roll your own, the agent builder is relatively easy to use... > And yes, it's more complicated than Disk -- Server -- Client, but you could > use that same argument for VMware.

VM is enterprise class, but not VMWare (but clever naming always helps make positive associations :-) -- richard _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
