Managing HP Serviceguard for Linux, Sixth Edition, August 2006

Planning and Documenting an HA Cluster
Package Configuration Planning
Chapter 4 115
On starting the package, the script may activate one or
more volume groups, and at halt time, the script
deactivates each volume group. All volume groups
must be accessible on each target node.
Include as many volume groups (VGs) as needed. If you
are using raw devices, the LV, FS, and FS_MOUNT_OPT
entries are not needed. Only cluster aware volume
groups should be specified in package control scripts.
To make a volume group cluster aware, enter it as part
of the cluster configuration. See above, “Cluster
Configuration Planning.”
MD Do not use this parameter; it is deprecated in
Serviceguard for Linux. (If used, the
MD array stores the
names of multiple devices that are employed for
storage in the package and defined in the RAIDTAB file.)
LV The name of a logical volume hosting a file system that
will be mounted by the package.
FS The name of the mount point for a file system to be
mounted by the package.
FS_TYPE The file system type of a file system being mounted by
the package. Three types of file systems are supported:
• ext2, the basic Linux file system
• ext3, a journaling file system that improves
performance when the file system is fsck’d.
• reiserfs, a journaling file system with B-tree data
storage.
ext3 is the default for Red Hat 3 and Red Hat 4.
reiserfs is the default for SLES9.
FS_MOUNT_OPT
The options that should be used with the mount
command when issued from the package control script
during package startup.
FS_UMOUNT_OPT
The options that should be used with the umount
command when issued from the package control script
during package shutdown.
