Chapter 7. Testing the NFS Cluster Service
- If the GFS file system in the
nfsclustcluster is currently empty, populate the file system with test data.
- Log in to one of the client systems you defined as a target.
- Mount the NFS file system on the client system, and check to see if the data on that file system as available.
- On the
Luciserver, select Nodes from the menu for
nfsclust. This displays the nodes in
nfsclustand indicates which node is running the
- The drop-down box for each node displays. For the node on which the
nfssvcservice is running, select .
- Refresh the screen. The
nfssvcservice should now be running in a different node.
- On the client system, check whether the file system you mounted is still available. Even though the NFS service is now running on a different node in the cluster, the client system should detect no difference.
- Restore the system to its previous state:
- Unmount the file system from the client system.
- Delete any test data you created in the GFS file system.
- Click onin the drop-down box for the node which you fenced and select .
kdumpservices on a system. You may find it useful to implement and test these tools before a system goes into production, to help in troubleshooting down the line.
