More like "you shouldn't let the SAN mess with the disks and let zfs see the disks as JBOD". ... but then again, your SAN might not let you do that. So my suggestion is actually just present one huge 25TB LUN to zfs and let the SAN handle redundancy. Or if your SAN can't do it either, just let it give whatever-biggest-size LUN that it can, and simply use stripe on zfs side. > > Or should I divide the zpool up and make several smaller zpools? If you're going to use them for a single purpose anyway (e.g. storing database files from a single db, or whatever), I don't see the benefit in doing that. -- Fajar _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
