Hi Omen,
raidz root will work in Nexenta when it works in vanilla Open
Solaris. I don't know what the schedule is but I do know it's being
worked on. The zfs-discuss archives might have more information on this.
I would suggest that you keep your entire root filesystem on the
mirror. apt-clone relies on this assumption in order to rollback
packaging decisions and does not snapshot/clone other filesystems. Also,
I would caution you to leave 2-3x as much space as you ever expect your
rootfs to be for the mirror to be safe about using apt-clone. This
should leave of space for package downloads and the overhead of new data
when the rootfs has been cloned/written to.
Thanks,
-Tim
