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 46verify_runnable "global" 47 48function 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 $TMPFILE 54} 55 56log_assert "zpool history limitation test." 57log_onexit cleanup 58 59mntpnt=$(get_prop mountpoint $TESTPOOL) 60(( $? != 0 )) && log_fail "get_prop mountpoint $TESTPOOL" 61 62VDEV0=$mntpnt/vdev0; VDEV1=$mntpnt/vdev1 63log_must $MKFILE 100m $VDEV0 $VDEV1 64 65spool=smallpool.$$; sfs=smallfs.$$ 66log_must $ZPOOL create $spool $VDEV0 $VDEV1 67log_must $ZFS create $spool/$sfs 68 69typeset -i orig_count=$($ZPOOL history $spool | $WC -l) 70typeset orig_md5=$($ZPOOL history $spool | $HEAD -2 | $MD5SUM | \ 71 $AWK '{print $1}') 72 73typeset -i i=0 74while ((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)) 82done 83 84TMPFILE=/tmp/spool.$$ 85$ZPOOL history $spool >$TMPFILE 86typeset -i entry_count=$($WC -l $TMPFILE | $AWK '{print $1}') 87typeset final_md5=$($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. 99if [[ $orig_md5 != $final_md5 ]]; then 100 log_fail "zpool creation history was not preserved." 101fi 102 103log_pass "zpool history limitation test passed." 104
