The test will also start 'sar' to monitor the system 25# utilization data. The purpose of this test is to stress the 26# NFS kernel code and possibly the underlying filesystem where 27# the export resides. A PASS is if the test completes. 28# 29# PREREQUISITE: There must exist an NFS exported filesystem available to 30# test on. 31# 32# 33# HISTORY: 34# 11/21/03 Robbie Williamson (robbiew@us.ibm.com) 35# -Written 36# 37#*********************************************************************** 38 39#Uncomment line below for debug output. 40#trace_logic=${trace_logic:-"set -x"} 41 42$trace_logic 43 44echo -n "Please enter the server location of the NFS exported filesystem: " 45read RHOST 46echo -n "Please enter the name of the NFS exported filesystem: " 47read FILESYSTEM 48echo -n "Please enter the test duration in hours: " 49read DURATION 50 51HOSTNAME=$(hostname | awk {'print $1'}) 52 53#Convert to seconds 54DURATION=$(( $DURATION * 60 * 60 )) 55 56echo "Setting up local mount points" 57mkdir -p /tmp/udp/2/${HOSTNAME}1 58mkdir -p /tmp/tcp/2/${HOSTNAME}2 59mkdir -p /tmp/udp/3/${HOSTNAME}3 60mkdir -p /tmp/tcp/3/${HOSTNAME}4 61 62echo "Mounting NFS filesystem" 63mount -o "intr,soft,proto=udp,vers=2" $RHOST:$FILESYSTEM /tmp/udp/2/${HOSTNAME}1 >/dev/null 2>&1 64if [ $? -ne 0 ];then 65 echo "Error: mount using UDP & version 2 failed" 66 exit 1 67fi 68mount -o "intr,soft,proto=tcp,vers=2" $RHOST:$FILESYSTEM /tmp/tcp/2/${HOSTNAME}2 >/dev/null 2>&1 69if [ $? -ne 0 ];then 70 echo "Error: mount using TCP & version 2 failed" 71 exit 1 72fi 73mount -o "intr,soft,proto=udp,vers=3" $RHOST:$FILESYSTEM /tmp/udp/3/${HOSTNAME}3 >/dev/null 2>&1 74if [ $? -ne 0 ];then 75 echo "Error: mount using UDP & version 3 failed" 76 exit 1 77fi 78mount -o "intr,soft,proto=tcp,vers=3" $RHOST:$FILESYSTEM /tmp/tcp/3/${HOSTNAME}4 >/dev/null 2>&1 79if [ $? -ne 0 ];then 80 echo "Error: mount using TCP & version 3 failed" 81 exit 1 82fi 83 84echo "Test set for $DURATION seconds.
