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, nfs-lock.service and nfs-server.service 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.
