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 (at] us.ibm.com) 35 # -Written 36 # 37 #*********************************************************************** 38 39 #Uncomment line below for debug output. 40 #trace_logic=${trace_logic:-"set -x"} 41 42 $trace_logic 43 44 echo -n "Please enter the server location of the NFS exported filesystem: " 45 read RHOST 46 echo -n "Please enter the name of the NFS exported filesystem: " 47 read FILESYSTEM 48 echo -n "Please enter the test duration in hours: " 49 read DURATION 50 51 HOSTNAME=$(hostname | awk {'print $1'}) 52 53 #Convert to seconds 54 DURATION=$(( $DURATION * 60 * 60 )) 55 56 echo "Setting up local mount points" 57 mkdir -p /tmp/udp/2/${HOSTNAME}1 58 mkdir -p /tmp/tcp/2/${HOSTNAME}2 59 mkdir -p /tmp/udp/3/${HOSTNAME}3 60 mkdir -p /tmp/tcp/3/${HOSTNAME}4 61 62 echo "Mounting NFS filesystem" 63 mount -o "intr,soft,proto=udp,vers=2" $RHOST:$FILESYSTEM /tmp/udp/2/${HOSTNAME}1 >/dev/null 2>&1 64 if [ $? -ne 0 ];then 65 echo "Error: mount using UDP & version 2 failed" 66 exit 1 67 fi 68 mount -o "intr,soft,proto=tcp,vers=2" $RHOST:$FILESYSTEM /tmp/tcp/2/${HOSTNAME}2 >/dev/null 2>&1 69 if [ $? -ne 0 ];then 70 echo "Error: mount using TCP & version 2 failed" 71 exit 1 72 fi 73 mount -o "intr,soft,proto=udp,vers=3" $RHOST:$FILESYSTEM /tmp/udp/3/${HOSTNAME}3 >/dev/null 2>&1 74 if [ $? -ne 0 ];then 75 echo "Error: mount using UDP & version 3 failed" 76 exit 1 77 fi 78 mount -o "intr,soft,proto=tcp,vers=3" $RHOST:$FILESYSTEM /tmp/tcp/3/${HOSTNAME}4 >/dev/null 2>&1 79 if [ $? -ne 0 ];then 80 echo "Error: mount using TCP & version 3 failed" 81 exit 1 82 fi 83 84 echo "Test set for $DURATION seconds.
