It seems that either the version of mkfs.lustre you are using has a
parsing bug, or there was some sort of syntax error in the actual
command entered.  If you are certain your command line is free from
errors, please post the version of lustre you are using, or report the
bug in the Lustre issue tracker.

Thanks,
