Urgent

I dont advice any body to use this command t reorganize file systems . I have experianced a disater on my cretical file systems after running fsadm -d -e /filesystem command.

Please dont use it.

In my company's production machine has this script to do that and it was recommended by HP CE to enhance the performance.

#!/bin/ksh
LOG=/tmp/defragJFS.log

echo "Please enter Directory to be defragmented : \c"
read D

if [ ! -d $D ]; then
echo "$0: Directory $D does not exist"
exit
fi
echo "Log file is: $LOG"
echo "WARNING: Old log file will be overwritten"
echo "Are you sure to defragment $D [N]: \c"
read dummy
if [ "$dummy" != "Y" -a "$dummy" != "y" ]; then
echo "User abort operation"
exit
fi
echo "Defragment start at `date`" > $LOG
#
# Report the Directory Fragmentation
/usr/sbin/fsadm -D $D | /usr/bin/tee -a $LOG 2>&1

#
# Report the Extent Fragmentation
/usr/sbin/fsadm -E $D | /usr/bin/tee -a $LOG 2>&1

# To Perform Directory and Extent Reorganization
/usr/sbin/fsadm -F vxfs -d -D -e -E $D | /usr/bin/tee -a $LOG 2>&1
/usr/sbin/fsadm -F vxfs -d -D -e -E $D | /usr/bin/tee -a $LOG 2>&1
/usr/sbin/fsadm -F vxfs -d -D -e -E $D | /usr/bin/tee -a $LOG 2>&1

echo "Defragment start at `date`" >> $LOG
