[ClusterLabs] restarting resources

Hi,
   I need to be able to restart a resource (e.g apache) whenever a
configuration
file is updated. I have been using the 'crm resource restart ' command to
to it,
which does restart the resource BUT also restarts my other resources also.
Is this normal behaviour? Is there a way to just/force restart only the
resource whose config file is changed.

I have the following resources configured in a group (ew)

 Resource Group: ew
     fs_drbd    (ocf::heartbeat:Filesystem):    Started ew-2
     VirtualIP  (ocf::heartbeat:IPaddr2):       Started ew-2
     mysqld-1   (ocf::heartbeat:mysql): Started ew-2
     mysqld-2   (ocf::heartbeat:mysql): Started ew-2
     Website8084        (ocf::heartbeat:apache):        Started ew-2
     Website8083        (ocf::heartbeat:apache):        Started ew-2
     Website8085        (ocf::heartbeat:apache):        Started ew-2
     Website8086        (ocf::heartbeat:apache):        Started ew-2
     tomcat8-9092       (ocf::heartbeat:tomcat):        Started ew-2
     tomcat7-9091       (ocf::heartbeat:tomcat):        Started ew-2
     tomcat5-9090       (ocf::heartbeat:tomcat):        Started ew-2
     pgsqld-1   (ocf::heartbeat:pgsql): Started ew-2
     Website8080        (ocf::heartbeat:apache):        Started ew-2
     mail       (ocf::heartbeat:MailTo):        Started ew-2
     p_sym_cron_rsync   (ocf::heartbeat:symlink):       Started ew-2

Now, if I restart say 'Website8086', all the other resources defined after
Website8086 in the listing above (tomcat8-9092 ... to p_sym_cron_rsync)
gets
restarted as well. This can take a while to complete.

Is there a way to just start Website8086 or just reload it, without
affecting
the other resources.

Thanks
