Re: [zfs-discuss] Help with the best layout
Thanks everybody :) The solution i'm using now is the one where i backup to the usb disk and settle for a mirror on the two smaller disks. This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

I thought that too, but actually, I'm not sure you can. You can stripe multiple mirror or raid sets with zpool create, but I don't see any documentation or examples for mirroring a raid set. However, in this case even if you could, you might not want to. Creating a stripe that way will restrict the speed of the IDE drives: They will be throttled back to the speed of the USB disk. What I would do instead is create a mirror of the two IDE drives, then use zfs send/receive to send regular backups to the USB drive.
