An IPaddr2 resource fails to start due to incorrectly calculating the netmask value in a RHEL 6 High Availability cluster with pacemaker

Solution In Progress - Updated -

Issue

  • My IPaddr2 resource won't start if I don't specify a cidr_netmask in the configuration
  • If I pcs resource debug-start an IPaddr2 resource, it shows it calculating an invalid netmask:
 >  stderr: IPaddr[10954]: INFO: Using calculated netmask for 192.168.143.65: 255.255.255.127

Environment

  • Red Hat Enterprise Linux (RHEL) 6 with the High Availability Add On
  • pacemaker
  • resource-agents prior to release 3.9.2-21.el6_4.7
  • One or more IPaddr2 resources
    • Resource does not have the cidr_netmask attribute specified in the configuration
    • Resource does have a nic attribute specified in the configuration
    • NOTE: IPaddr is an alias for IPaddr2, so it too is affected by this issue
