You can actually change the partitions while you're using the slice. But after changing the size of both slices you may need to reboot I've used it also when going from ufs to zfs for boot. >However I'm not sure if raid-10 (two mirrors striped in your case) is >allowed for rpools... Nope: a mirror will work (just boot from one of the devices until the kernel is loaded) and you can even compress the root filesystem (with the standard compress algorithm) Casper _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
