Configuring Packages and Their Services
Choosing Package Modules
Chapter 6222
File system parameters
A package can activate one or more storage groups on startup, and to
mount logical volumes to file systems. At halt time, the package script
unmounts the file systems and deactivates each storage group. All
storage groups must be accessible on each target node.
For each file system you specify in the package configuration file (see
fs_name on page 224), you must identify a logical volume, the mount
point, the mount, umount and fsck options and type of the file system; for
example:
fs_name /dev/vg01/lvol1
fs_directory /pkg01aa
fs_mount_opt "-o rw"
fs_umount_opt ""
fs_fsck_opt ""
fs_type "ext2"
A logical volume must be built on an LVM volume group. Logical volumes
can be entered in any order.
A gfs file system can be configured using only the fs_name,
fs_directory, and fs_mount_opt parameters; see the configuration file
for an example. Additional rules apply for gfs as explained under
fs_type (see page 225).
The parameter explanations that follow provide more detail.
concurrent_fsck_operations
The number of concurrent fsck operations allowed on file systems being
mounted during package startup. Not used for Red Hat GFS (see
fs_type on page 225).
Legal value is any number greater than zero. The default is 1.
If the package needs to run fsck on a large number of file systems, you
can improve performance by carefully tuning this parameter during
testing (increase it a little at time and monitor performance each time).
