rgmanager in a cluster reports "<err> Unique attribute collision" in RHEL

Solution Unverified - Updated -


  • I see "unique attribute collision" errors in my logs
clurgmgrd[22019]: <err> Unique attribute collision. type=fs attr=mountpoint value=/mount
  • cluster is unable to run 2 services at the same time, reporting "Unique attribute collision"


  • Red Hat Enterprise Linux (RHEL) 5 or 6 with the High Availability Add On
  • Red Hat Cluster Suite (RHCS) 4
  • Multiple resources in /etc/cluster/cluster.conf that share the same value for a unique attribute for that type (see Root Cause below for more information).
