Create two 100M virtual disk files. 40 # 2. Create test pool using the two virtual files. 41 # 3. Loop 100 times to set and remove compression to test dataset. 42 # 4. Make sure 'zpool history' output is truncated 43 # 5. Verify that the initial pool creation is preserved. 44 # 45 46 verify_runnable "global" 47 48 function cleanup 49 { 50 datasetexists $spool && log_must $ZPOOL destroy $spool 51 [[ -f $VDEV0 ]] && log_must $RM -f $VDEV0 52 [[ -f $VDEV1 ]] && log_must $RM -f $VDEV1 53 [[ -f $TMPFILE ]] && log_must $RM -f $TMPFILE 54 } 55 56 log_assert "zpool history limitation test." 57 log_onexit cleanup 58 59 mntpnt=$(get_prop mountpoint $TESTPOOL) 60 (( $? != 0 )) && log_fail "get_prop mountpoint $TESTPOOL" 61 62 VDEV0=$mntpnt/vdev0; VDEV1=$mntpnt/vdev1 63 log_must $MKFILE 100m $VDEV0 $VDEV1 64 65 spool=smallpool.$$; sfs=smallfs.$$ 66 log_must $ZPOOL create $spool $VDEV0 $VDEV1 67 log_must $ZFS create $spool/$sfs 68 69 typeset -i orig_count=$($ZPOOL history $spool | $WC -l) 70 typeset orig_md5=$($ZPOOL history $spool | $HEAD -2 | $MD5SUM | \ 71 $AWK '{print $1}') 72 73 typeset -i i=0 74 while ((i < 100)); do 75 $ZFS set compression=off $spool/$sfs 76 $ZFS set compression=on $spool/$sfs 77 $ZFS set compression=off $spool/$sfs 78 $ZFS set compression=on $spool/$sfs 79 $ZFS set compression=off $spool/$sfs 80 81 ((i += 1)) 82 done 83 84 TMPFILE=/tmp/spool.$$ 85 $ZPOOL history $spool >$TMPFILE 86 typeset -i entry_count=$($WC -l $TMPFILE | $AWK '{print $1}') 87 typeset final_md5=$($HEAD -2 $TMPFILE | $MD5SUM | $AWK '{print $1}') 88 89 $GREP 'zpool create' $TMPFILE >/dev/null 2>&1 || 90 log_fail "'zpool create' was not found in pool history" 91 92 $GREP 'zfs create' $TMPFILE >/dev/null 2>&1 && 93 log_fail "'zfs create' was found in pool history" 94 95 $GREP 'zfs set compress' $TMPFILE >/dev/null 2>&1 || 96 log_fail "'zfs set compress' was found in pool history" 97 98 # Verify that the creation of the pool was preserved in the history. 99 if [[ $orig_md5 != $final_md5 ]]; then 100 log_fail "zpool creation history was not preserved." 101 fi 102 103 log_pass "zpool history limitation test passed."
