Both copies may end up on the same disk. zfs will try to put your copies on diffrent disks, but it won't tell you if it can't. Use mirror or RAIDZ if your data is important! _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
