If he was pushing 10 > data disks that'd be another story. if i went raidz2 i'd want the entire 14 disk array in it i think. i'd rather not do a raidz2 with less than 100% of the disks and then a second raidz1 (or 2) because i'd wind up losing much more disk space. essentially, i am willing to give up 2 of 14 disks (roughly of course) to parity. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
