NFS Resource Monitor Process

Before starting the resource monitor probes, all of the shared paths are read from the dfstab file and stored in memory. In each probe cycle, all of the shared paths are probed in each iteration by performing stat() on the path.

Each resource monitor fault probe performs the following steps.

1. Sleeps for Thorough_probe_interval.

2. Refreshes the memory if dfstab has been changed since the last read.

3. Probes all of the shared paths in each iteration by performing stat() of the path.

If any path is not functional, the resource status is set to FAULTED. If all of the paths are functional, the resource status is set to ONLINE again.
