AVS (or Availability Suite) .. http://www.opensolaris.org/os/project/avs/ Jim Dunham does a nice demo here for block replication on zfs (see sidebar) > What isn't clear is if zfs send/recv retains inode numbers... if it > doesn't that's a really sad thing, as we won't be able to use ZFS to > replace NetApp snapmirrors. zfs send/recv comes out of the DSL which i believe will generate a unique fsid_guid .. for mirroring you'd really want to use AVS. btw - you can also look at the Cluster SUNWnfs agent in the ohac community: http://opensolaris.org/os/community/ha-clusters/ohac/downloads/ hth --- .je _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
