Managing HP Serviceguard for Linux Ninth Edition, April 2009

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.
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).
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).
concurrent_mount_and_umount_operations
The number of concurrent mounts and umounts to allow during package startup or
shutdown.
Legal value is any number greater than zero. The default is 1.
If the package needs to mount and unmount 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).
fs_mount_retry_count
The number of mount retries for each file system. Legal value is zero or any greater
number. The default is zero. The only valid value for Red Hat GFS (see fs_type) is zero.
If the mount point is busy at package startup and fs_mount_retry_count is set to zero,
package startup will fail.
If the mount point is busy and fs_mount_retry_count is greater than zero, the startup
script will attempt to kill the user process responsible for the busy mount point (fuser
-ku) and then try to mount the file system again. It will do this the number of times
specified by fs_mount_retry_count.
If the mount still fails after the number of attempts specified by fs_mount_retry_count,
package startup will fail.
This parameter is in the package control script for legacy packages.
