Before installing and configuring the LifeKeeper NFS Server Recovery Kit, be sure that your configuration meets the following requirements:

  • LifeKeeper IP Recovery Kit. You must have the same version of the LifeKeeper IP Recovery Kit on each server.
  • IP network interface. Each server requires at least one Ethernet TCP/IP-supported network interface. In order for IP switchover to work properly, user systems connected to the local network should conform to standard TCP/IP specifications.
  • TCP/IP software. Each server also requires the TCP/IP software.
  • nfs-utils software. Each server must have a high availability enabled version of the nfs-utils package installed and configured prior to configuring LifeKeeper and the LifeKeeper NFS Server Recovery Kit (on some OS distributions, nfs-utils is provided via another package). The same version must be installed on each server.

The LifeKeeper Installation Support setup script will configure nfs-utils for use in an HA environment. Additionally, when using the kit to protect NFS v2/v3 exports, the init scripts NFS lock (/etc/init.d/nfslock) and NFS server (/etc/init.d/nfs or /etc/init.d/nfsserver depending on the Linux distribution) should be configured to start automatically on system boot. When protecting NFS v4 root exports, they should not be configured to automatically start at boot.
