Why would you use NFS? These zones are on the same machine as the storage, right? You can simply export filesystems in your pool to the various zones (see zfs(1m) and zonecfg(1m) manpages). This will result in better performance. > 5 - Multiple disk redundancy is needed. So, I'm assuming two raid-z > pools of 3 drives each, mirrored is the solution. If people have a > better suggestion, tell me! :P There is no need for multiple pools. Perhaps you meant two raid-z groups (aka "vdevs") in a single pool? Also, wouldn't you want to use all 8 disks, therefore use two 4-disk raid-z groups? This way you would get 3 disks worth of usable space. Depending on how much space you need, you should consider using a single double-parity RAID-Z group with your 8 disks. This would give you 6 disks worth of usable space. Given that you want to be able to tolerate two failures, that is probably your best solution. Other solutions would include three 3-way mirrors (if you can fit another drive in your machine), giving you 3 disks worth of usable space. --matt _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
