Currently, you can either replace the individual disks to upgrade 3x750 to 3x2TB or whatever disks you buy next.. that requires no extra ports.. Or you can just add a 3x2TB raidz1 along with the 3x750.. Unless you want to rebuild it into a 6 disk raidz(1/2), there's not much need to re-create the pool.. But that will require sufficient storage somewhere else during the time.. /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
