Alex,

Support for these rules was just recently added into pcs and are currently 
present in F18.  If you'd like I can build you a test package for F18 (that will 
be similiar to what will be released for F19 soon).

The syntax would look something like this:
pcs constraint location Asterisk rule -INFINITY: not_defined pingd or pingd lte

I'm still adding support for resource_sets (should be in by the end of this 
week).  I can let you know as soon as that is ready to go.  But that syntax will 
look something similiar to this:

pcs constraint colocation add ( Master rseries0 with Master rseries1_ms with 
Master Asterisk_ms ) with (ClusterIP with Asterisk_fs) with (Asterisk) INFINITY

pcs constraint order add ( promote rseries0_ms then promote rseries1_ms then 
promote Asterisk_ms ) then (ClusterIP then Asterisk_fs) then (start Asterisk)

Thanks!
Chris
