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 snapexists $snap && destroy_dataset $snap 59 done 60 61 if ! poolexists $TESTPOOL && is_global_zone; then 62 log_must zpool create $TESTPOOL $DISK 63 fi 64 65 if ! datasetexists $TESTPOOL/$TESTFS; then 66 log_must zfs create $TESTPOOL/$TESTFS 67 log_must zfs set mountpoint=$TESTDIR $TESTPOOL/$TESTFS 68 fi 69} 70 71function restore_dataset 72{ 73 if ! datasetexists $TESTPOOL/$TESTFS ; then 74 log_must zfs create $TESTPOOL/$TESTFS 75 log_must zfs set mountpoint=$TESTDIR $TESTPOOL/$TESTFS 76 log_must cd $TESTDIR 77 echo hello > world 78 log_must zfs snapshot $TESTPOOL/$TESTFS@$TESTSNAP 79 log_must cd .zfs/snapshot/$TESTSNAP 80 fi 81} 82 83 84log_assert "zfs force unmount and destroy in snapshot directory will not cause error." 85log_onexit cleanup 86 87for fs in $TESTPOOL/$TESTFS $TESTPOOL ; do 88 typeset snap=$fs@$TESTSNAP 89 typeset mtpt=$(get_prop mountpoint $fs) 90 91 log_must cd $mtpt 92 echo hello > world 93 log_must zfs snapshot $snap 94 log_must cd .zfs/snapshot/$TESTSNAP 95 96 log_mustnot zfs unmount -a 97 if is_linux; then 98 log_mustnot zfs unmount -fa 99 log_must ls 100 else 101 log_must zfs unmount -fa 102 log_mustnot ls 103 fi 104 log_must cd / 105 106 log_must zfs mount -a 107 log_must cd $mtpt 108 log_must cd .zfs/snapshot/$TESTSNAP 109 110 if is_global_zone || [[ $fs != $TESTPOOL ]] ; then 111 if is_linux; then 112 log_mustnot zfs destroy -rf $fs 113 log_must ls 114 else 115 log_must zfs destroy -rf $fs 116 log_mustnot ls 117 fi 118 log_must cd / 119 fi 120 121 restore_dataset 122done 123 124if is_global_zone ; then 125 if is_linux; then 126 log_mustnot zpool destroy -f $TESTPOOL 127 log_must ls 128 else 129 log_must zpool destroy -f $TESTPOOL 130 log_mustnot ls 131 fi 132 log_must cd / 133fi 134 135log_must eval zfs list > /dev/null 2>&1 136log_must eval zpool list > /dev/null 2>&1 137log_must eval zpool status > /dev/null 2>&1 138zpool iostat > /dev/null 2>&1 139 140log_pass "zfs force unmount and destroy in snapshot directory will not cause error." 141
