rgmanager in a cluster reports "<err> Unique attribute collision" in RHEL
Issue
- 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"
Environment
- 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).
