Hello Ulrich,

thanks, interesting hint. I took a look in my old config's backup, and 
indeed, my group was configured the other way round:

group gr_apache res_apache res_haweb_ip \
         meta target-role="Started"

I changed that to your suggestion:

group gr_apache res_haweb_ip res_apache \
	meta target-role="Started"

removed the colocation, switched on the group configured that way and 
indeed: that way it's possible to do a

crm resource restart res_apache

without affecting the IP. Learned something new again ;)
Thank you :)
