The parenthesis for colocation/order constraints are the way for the crm shell to express "sequential=false" for resource-sets so they have really nothing to do with specifying precedence of logical operators IMHO. > could I set up parenthetic "location"? > for example; > > location rsc_location-1 msDRBD \ > rule role=master -inf: \ > (defined master-prmMySQL:0 and master-prmMySQL:0 gt 0) or \ > (defined master-prmMySQL:1 and master-prmMySQL:1 gt 0) Why not using two rules for this location constraint? I expect that to work the same way you want to express in your rule above.
