Thus, you could do this: (1) Install system A (2) hook USB drive to A, and mount it at /mnt (3) use 'zfs send tank/root > /mnt/root' to save off the root ZFS filesystem to the USB drive (4) boot system B from CD/DVD, either to single-user mode, or to the graphical installer. (5) manually set up your zpools and zfs filesystems (6) plug in the USB drive, again mounting it at (say) /mnt (7) use 'cat /mnt/root | zfs receive tank/root' to restore the root filesystem Note that this will create an EXACT DUPLICATE, with the same name, IP address, etc. You should then run 'sys-unconfig', reboot the system, at which time it will ask you for a new name/ip/nameservice, etc. Alternately (and, preferably, in my opinion), do this: (1) set up system A. (2) mount USB drive (or, just a spare partition on A) on /mnt (3) flarcreate -n myclone -c -S -x /mnt /mnt/myclone.flar (4) NFS share /mnt (4) boot system B via DVD/CD (5) during installation, after network config chose 'flash archive' as the media, and choose the NFS path A:/mnt/myclone.flar as the source, you should be able to do filesystem layout afterwards, picking your favorite ZFS layout then. (6) wait - after the install, the system will reboot and ask you to input the name/ip/nameservice info. Note: I have not tried this yet, but it _should_ be straightforward. -- Erik Trimble Java System Support Mailstop: usca22-123 Phone: x17195 Santa Clara, CA Timezone: US/Pacific (GMT-0800) _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
