Can gmirror be used for this?
We have FreeBSD boxes that consist of four physical drives. We want to divide each of these drives into two slices, where slice s1 will be used strictly for the OS (partitioned with /, /var, swap, etc) and slice s2 (partitioned as one large partition) will be used strictly for data that is managed by our application.
We need to provide a level of HA into our system and what we'd like to do is mirror the OS slice across all four drives (or at least two of them) so that if the main boot drive goes down the system will still boot with the other three drives. We do not want to mirror the second slice, since each drive will contain different information in this slice.
Can we setup this kind of configuration?
