# GFS6.0 uses pool for logical volume management whereas GFS6.1 uses

LVM2.

# Their device name formats differ and an example for each is shown

below.

# Please use the appropriate one.

# Pool : /dev/pool/pool1 (GFS 6.0) O

# LVM2 : /dev/mapper/vgX

lvY (GFS6.1)

# mount point : /pkg1a

# filesystem type : gfs

# mount options : read/write

# Then the following would be entered:

# LV[0]=/dev/pool/pool1; (GFS6.0) OR

# LV[0]=/dev/mapper/

vgX

lvY; (GFS6.1)

# FS[0]=/pkg1a; FS_TYPE[0]="gfs";

# FS_MOUNT_OPT[0]="

# FILESYSTEM UNMOUNT COUNT

# Specify the number

of unmount attempts for each filesystem during

package

# shutdown. The default is set to 1.

# This particular variable is ignored if the underlying file system

# is Red Hat GFS.

FS_UMOUNT_COUNT=1

# FILESYSTEM MOUNT RETRY COUNT.

# Specify the number o

f mount retrys for each filesystem.

# The default is 0. During startup, if a mount point is busy

# and FS_MOUNT_RETRY_COUNT is 0, package startup will fail and

# the script will exit with 1. If a mount point is busy and

# FS_MOUNT_RETRY_COUNT is greate

r than 0, the script will attempt

# to kill the process(s) responsible for the busy mount point

# and then mount the file system. It will attempt to kill user and

# retry mount, for the number of times specified in

FS_MOUNT_RETRY_COUNT.

# If the mount s

till fails after this number of attempts, the script

# will exit with 1.

# NOTE: If the FS_MOUNT_RETRY_COUNT > 0, the script will execute

# "fuser

kuv" to freeup busy mount point.

# FS_MOUNT_RETRY_COUNT must be set to zero (default), if the underlying

file system is of type Red Hat GFS.

FS_MOUNT_RETRY_COUNT=0

# Configuring the concurrent operations below can be used to improve

the

# performance for starting up or halting a package. The maximum value

for

# each concurrent operation parameter is 10

24. Set these values

carefully.

# The performance could actually decrease if the values are set too

high
