let A,B,C,D be the 250GB disks and X,Y the 500GB ones. my choise here would be raidz over (A+B),(C+D),X,Y
means something like zpool create tank raidz (stripe A B) (stripe C D) X Y (how do you actually write that up as zpool commands?) _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
