You can do that. Other people have before. But IMHO, it demonstrates a faulty way of thinking. "SSD's are big and cheap now, so I can buy one of these high performance things, and slice it up!" In all honesty, GB availability is not your limiting factor. Speed is your limiting factor. That's the whole point of buying the thing in the first place. If you have 3 SSD's, they're each able to talk 3Gbit/sec at the same time. But if you buy one SSD which is 3x larger, you save money but you get 1/3 the speed. Whether you are using multiple HDD's or multiple SSD's, you're probably doing it because you want size, speed, and reliability better than a single disk. You're defeating all of these purposes by trying to leverage a single disk for your OS, l2arc, and log devices simultaneously. That's not to say there's never a situation where it makes sense. Other people have done it, and maybe it makes sense for you. But probably not. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
