Toolkit sends an alert email with failure messages in the following scenarios when:
• NFS daemon is not running on the node.
Message: <process_name> process is not running. NFS toolkit package <package_name>
failed on node <node_name>.
• RPC daemons fails to ping after specified number of retries.
Message: Unable to ping <process_name> process. NFS toolkit package <package_name>
failed on node <node_name>.
• rmtab synchronization process is not running.
Message: rmtab synchronization process is not running. NFS toolkit package
<package_name> failed on node <node_name>
• rpc.idmapd process is not running.
Message: rpc.idmapd process is not running. NFS toolkit package <package_name>
failed on node <node_name>.
• File lock migration script has gone down.
Message: File Lock Migration script has gone down. NFS toolkit package <package_name>
failed on node <node_name>.
Mounting NFS shares at client node
Using the package name in the mount command, you must NFS-mount a file system on the client
system. The package name is associated with the relocatable IP address of the package. On the
client systems, you must use a hard mount. For auto-mounter, the timeout must be greater than the
total end-to-end recovery time for the Serviceguard NFS package, which includes failover time,
running fsck, mounting file systems, and exporting file systems on the new node. The default
value of the timeout is five minutes. If you set the timeout to zero, it does not allow you to unmount.
Rolling Upgrade
The toolkit package nodes in a cluster can be upgraded with the new toolkit, on one node at a
time. Follow the instructions below to do so:
1. Backup the package directory and package control scripts if any.
2. Move the running NFS toolkit packages from the node that is being upgraded to another
package node.
3. Upgrade the NFS toolkit using the following command:
rpm -Uvh --nopostun
serviceguard-nfs-toolkit<version_number>.<OS_distro>.noarch.rpm
4. Verify the installation, using the following command:
rpm -q serviceguard-nfs-toolkit
The system displays the following output:
serviceguard-nfs-toolkit-<version number>
5. Repeat the above steps on all the other package nodes in the cluster.
