Unless I misunderstand, I think the intent of the OP question is how to do bare metal recovery after some catastrophic failure. In this situation, recovery is much more complex than what the ZFS Admin Guide says above. You would need to boot from CD, and partition and format the disk, then create a pool, and create a filesystem, and "zfs send | zfs receive" into that filesystem, and finally install the boot blocks. Only some of these steps are described in the ZFS Admin Guide, because simply expanding the rpool is a fundamentally easier thing to do. Even though I think I could do that ... I don't have a lot of confidence in it, and I can certainly imagine some pesky little detail being a problem. This is why I suggested the technique of: Reinstall the OS just like you did when you first built your machine, before the catastrophy. It doesn't even matter if you make the same selections you made before (IP address, package selection, authentication method, etc) as long as you're choosing to partition and install the bootloader like you did before. This way, you're sure the partitions, format, pool, filesystem, and bootloader are all configured properly. Then boot from CD again, and "zfs send | zfs receive" to overwrite your existing rpool. And as far as I know, that will take care of everything. But I only feel like 90% confident that would work. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
