For cross-machine tolerance, it should be possible (once the iSCSI target is integrated) to create ZFS-backed iSCSI targets and then use RAID-Z from a single host across machines. This is not a true clustered filesystem, as it has a single point of access, but it does get you beyond the 'single node = dataloss' mode of failure. As for the true clustered filesystem, we're still gathering requirements. We have some ideas in the pipeline, and it's definitely a direction in which we are headed, but there's not much to say at this point. - Eric -- Eric Schrock, Solaris Kernel Development http://blogs.sun.com/eschrock _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
