Stopping, starting, or relocating a cluster service with a large number of fs resources takes a long time in RHEL 6
Issue
- In my cluster, starting or stopping a service with a large number of fs resources takes a long time.
- One service group has 245 ext4 filesystems (exported out to 3 subnets). It is taking over 17 minutes to start the resource group, which seems unreasonable.
Environment
- Red Hat Enterprise Linux (RHEL) 6 with the High Availability Add On
- A High Availability cluster utilizing
rgmanager
resource-agents
prior to release3.9.2-40.el6
- A service containing a large number of
fs
resources
