Or available physical space in the case. For example a home server or small consumer NAS appliance where you want to maximize the space available for the "user data" ZFS pool and keep the OS in a completely separate pool but don't have the space for even a 2.5" drive. This is exactly the situation have have and I'm planning on migrating the OS to a consumer SSD (A San Disk Extreme III) via an IDE/CF adaptor, thus keeping OS and data pools separate. -- Darren J Moffat _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
