Create a file in a zfs filesystem, snapshot it and change directory to snapshot directory 40# 2. Verify that 'zfs unmount -a' will fail and 'zfs unmount -fa' will succeed 41# 3. Verify 'ls' and 'cd /' will succeed 42# 4. 'zfs mount -a' and change directory to snapshot directory again 43# 5. Verify that zfs destroy snapshot will succeed 44# 6. Verify 'ls' and 'cd /' will succeed 45# 7. Create zfs filesystem, create a file, snapshot it and change to snapshot directory 46# 8. Verify that zpool destroy the pool will succeed 47# 9. Verify 'ls' 'cd /' 'zpool list' and etc will succeed 48# 49 50verify_runnable "both" 51 52function cleanup 53{ 54 DISK=${DISKS%% *} 55 56 for fs in $TESTPOOL/$TESTFS $TESTPOOL ; do 57 typeset snap=$fs@$TESTSNAP 58 if snapexists $snap; then 59 log_must zfs destroy $snap 60 fi 61 done 62 63 if ! poolexists $TESTPOOL && is_global_zone; then 64 log_must zpool create $TESTPOOL $DISK 65 fi 66 67 if ! datasetexists $TESTPOOL/$TESTFS; then 68 log_must zfs create $TESTPOOL/$TESTFS 69 log_must zfs set mountpoint=$TESTDIR $TESTPOOL/$TESTFS 70 fi 71} 72 73function restore_dataset 74{ 75 if ! datasetexists $TESTPOOL/$TESTFS ; then 76 log_must zfs create $TESTPOOL/$TESTFS 77 log_must zfs set mountpoint=$TESTDIR $TESTPOOL/$TESTFS 78 log_must cd $TESTDIR 79 echo hello > world 80 log_must zfs snapshot $TESTPOOL/$TESTFS@$TESTSNAP 81 log_must cd .zfs/snapshot/$TESTSNAP 82 fi 83} 84 85 86log_assert "zfs fource unmount and destroy in snapshot directory will not cause error." 87log_onexit cleanup 88 89for fs in $TESTPOOL/$TESTFS $TESTPOOL ; do 90 typeset snap=$fs@$TESTSNAP 91 typeset mtpt=$(get_prop mountpoint $fs) 92 93 log_must cd $mtpt 94 echo hello > world 95 log_must zfs snapshot $snap 96 log_must cd .zfs/snapshot/$TESTSNAP 97 98 log_mustnot zfs unmount -a 99 log_must zfs unmount -fa 100 log_mustnot ls 101 log_must cd / 102 103 log_must zfs mount -a 104 log_must cd $mtpt 105 log_must cd .zfs/snapshot/$TESTSNAP 106 107 if is_global_zone || [[ $fs != $TESTPOOL ]] ; then 108 log_must zfs destroy -rf $fs 109 log_mustnot ls 110 log_must cd / 111 fi 112 113 restore_dataset 114done 115 116if is_global_zone ; then 117 log_must zpool destroy -f $TESTPOOL 118 log_mustnot ls 119 log_must cd / 120fi 121 122log_must eval zfs list > /dev/null 2>&1 123log_must eval zpool list > /dev/null 2>&1 124log_must eval zpool status > /dev/null 2>&1 125zpool iostat > /dev/null 2>&1 126 127log_pass "zfs fource unmount and destroy in snapshot directory will not cause error." 128
