Understanding the Serviceguard NFS Files
Serviceguard NFS uses files similar and typical to Serviceguard. These
include configuration files, control scripts, monitoring scripts, and
templates. As is true for all Serviceguard packages, you configure and
view a small number of files. The following is a brief description of the
files:
• Files that apply to the whole cluster:
— cluster configuration file, cluster.conf
Defines the cluster nodes, shared networks, and max # of
packages
— raidtab.sg
Defines the HA storage devices (MDs) for all the packages.
• Files that apply to each NFS package (<pkg>):
— package configuration file, <pkg>.conf
The master package configuration file. It defines the package’s
nodes and failover behavior, and points to the package’s control
script, pkg.cntl.
— package control script, <pkg>.cntl
This defines the start and stop behavior, especially the activation
and de-activation of the HA storage, and calls the toolkit.sh file.
— Toolkit configuration script, hanfs.conf
— NFS control script, hanfs.sh
This exports the HA file system managed by this package. If
specified, it also starts monitoring the NFS services.
— <pkg.cntl>.log and hanfs.sh.log files
These are generated automatically.
— NFS monitoring script, nfs.mon
— Toolkit interface script, toolkit.sh
This script is invoked by <pkg>.cntl,which invokes the
hanfs.sh.
