Version 5.0.0 and greater of the LifeKeeper NFS Server Recovery Kit requires the installation and configuration of a high availability enabled nfs-utils package (on some OS distribution versions, nfs-utils is provided via another package). The Recovery Kit will attempt to verify the presence of this HA enabled nfs-utils package. If it fails to detect a correctly configured nfs-utils package, the LifeKeeper Installation Support setup script may need to be rerun or the server may need to be rebooted.
The LifeKeeper Installation Support setup script will configure nfs-utils for use in an HA environment and will also perform setup configuration for NFS v4 exports. You must answer YES to this HA NFS question for any NFS version that will be used.
The configuration needed for NFS v4 requires the movement of rpc_pipefs from /var/lib/nfs to /var/lib. To do this may require the unloading of kernel modules and the addition or modification of configuration and boot time scripts. A system reboot may be required if Installation Support is unable to unload and reload kernel modules after the change. If this should occur, the user will be notified of the need for a system reboot. Completing the rpc_pipefs setup including a system reboot is required for successful operation of LifeKeeper.
