Scripts
This chapter describes GFS

12.1. GFS
init.d
Scripts Overview
The GFS
init.d
scripts start GFS services during node startup and stop GFS services during node
shutdown. Also, the scripts provide functions for querying the status of GFS services (for example, if
a service is running or stopped).
The GFS
init.d
scripts are stored in the directory
/etc/init.d
and accept one of the following
parameters:
start
,
stop
or
status
. For example, to start the
gfs.o
module, call the
gfs init.d
script as follows:
#
/etc/init.d/gfs start
As with other
init.d
scripts, wrappers are available for using the scripts. For example you can use
service
or
serviceconf
.
GFS provides the following init.d scripts that are installed automatically when GFS is installed:
•
pool
• ccsd
•
lock_gulmd
• gfs
The scripts automatically start and stop GFS modules during startup and shutdown of a node. When
GFS is installed, the scripts are stored in the
/etc/init.d
directory. In addition, installation auto-
matically names and places the scripts into directories
rc0.d
through
rc6.d
so that the GFS modules
will be started and stopped in the correct order.
If you use the scripts manually to start and shut down GFS modules, you must run the scripts in a
certain order. For startup, follow this sequence:
pool
,
ccsd
,
lock_gulmd
, and
gfs
. For shutdown,
follow this sequence:
gfs
,
lock_gulmd
,
ccsd
, and
pool
.
The following example shows running the GFS
init.d
scripts to start up GFS:
#
service pool start
#
service ccsd start
#
service lock_gulmd start
#
service gfs start
The following example shows running the GFS
init.d
scripts to shut down GFS:
#
service gfs stop
#
service lock_gulmd stop
#
service ccsd stop
#
service pool stop
