Creates a data file of specified or random size and copies 25 # the file to a random directory depth on a specified filesystem 26 # The two files are compared and checked for differences. 27 # If the files differ, then the test fails. By default, this 28 # test creates a 30Mb file and runs for ten loops. 29 # 2. Creates a datafile of size half of the partition size. Creates 30 # two fragmented files on the specified partition and copies datafile 31 # to them. Then compares both the fragmented files with datafile. If 32 # files differ, then test fails. 33 # 34 # SETUP: None 35 # 36 # 37 # HISTORY: 38 # 28/07/09 Jyoti Vantagodi (jyotiv (at] linux.vnet.ibm.com) 39 # Added point two of above PURPOSE 40 # 04/11/05 Robbie Williamson (robbiew (at] us.ibm.com) 41 # -Written 42 # 43 #*********************************************************************** 44 45 #Uncomment line below for debug output. 46 #trace_logic=${trace_logic:-"set -x"} 47 48 $trace_logic 49 50 #----------------------------------------------------------------------- 51 # Initialize local variables 52 #----------------------------------------------------------------------- 53 TC=${TC:=fs_di} 54 TCbin=${TCbin:=`pwd`} 55 TCtmp=${TCtmp:=$TMPDIR/$TC$$} 56 export PATH=$PATH:$TCbin:../../../bin 57 export TCID=$TC 58 export TST_TOTAL=1 59 export TST_COUNT=1 60 61 # If CLEANUP is not set; set it to "ON" 62 CLEANUP=${CLEANUP:="ON"} 63 usage() 64 { 65 cat <<-EOF >&2 66 67 usage: ./${0##*/} -d TMPDIR [-h] [-l # of LOOPS ] [-s SIZE in Mb][-S partition SIZE in Mb] 68 69 -d TMPDIR Directory where temporary files will be created. 70 -h Help.
