D.2. Enforcing Resource Timeouts

There is no timeout for starting, stopping, or failing over resources. Some resources take an indeterminately long amount of time to start or stop. Unfortunately, a failure to stop (including a timeout) renders the service inoperable (failed state). You can, if desired, turn on timeout enforcement on each resource in a service individually by adding __enforce_timeouts="1" to the reference in the cluster.conf file.
The following example shows a cluster service that has been configured with the __enforce_timeouts attribute set for the netfs resource. With this attribute set, then if it takes more than 30 seconds to unmount the NFS file system during a recovery process the operation will time out, causing the service to enter the failed state.

    <netfs export="/nfstest" force_unmount="1" fstype="nfs" host="" 
           mountpoint="/data/nfstest" name="nfstest_data" options="rw,sync,soft"/>
  <service autostart="1" exclusive="0" name="nfs_client_test" recovery="relocate">
    <netfs ref="nfstest_data" __enforce_timeouts="1"/>
