Understanding the MC/ServiceGuard NFS
Files
MC/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. Three of these, toolkit.sh, nfs.mon and
ha.nfs are new to MC/ServiceGuard NFS. 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 hanfs.sh.
— 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
