If add more than eight nodes, how to add it? 

now, when add mon.7 for eighth node, there have a error:
unable to find usable monitor id (500)

##Ceph.pm 
 825         my $monid;
 826         for (my $i = 0; $i < 7; $i++) {
 827             if (!$cfg->{"mon.$i"}) {
 828                 $monid = $i;
 829                 last;
 830             }
 831         }

just modify here ?
