Round-robin across all vdevs (single disk, mirror, raidz, raidz2) in a pool. > What other ZFS features depend on ZFS RAID ? Mostly the self-healing stuff.. But if it's not zfs-redundant and a device experiences write errors, the machine will currently panic. /Tomas -- Tomas Ögren, [EMAIL PROTECTED], http://www.acc.umu.se/~stric/ |- Student at Computing Science, University of Umeå `- Sysadmin at {cs,acc}.umu.se _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
