Steps to reproduce:
1. Start up worker node with wfr and file repo on the same nfs share
2. Examine logs for state of hard linking, e.g.
grep Hard /opt/matterhorn/logs/opencast.log
2015-02-22 10:43:50 INFO [FelixStartLevel] (WorkspaceImpl:175) - Hard links between the working file repository and the workspace enabled
Sometimes the worker node reports that hard links are not possible, e.g.:
2015-02-22 13:07:22 WARN [FelixStartLevel] (WorkspaceImpl:177) - Hard links between the working file repository and the workspace are not possible
Restarting the worker node (sometimes a few times) produces a successful detection.
Hard links should be detected consistently.
Workaround (if any):
Examine status on startup and restart if required.
