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 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
  This script is invoked by <pkg.cntl>.cntl,which invokes the hanfs.sh.
