The test creates 50 filesystem and 50 threads. 33# Each thread will run through the test strategy in parallel. 34# 35# STRATEGY: 36# 1. Verify that the file system is not shared. 37# 2. Enable the 'sharenfs' property 38# 3. Invoke 'zfs unshare' and verify filesystem is no longer shared 39# 4. Invoke 'zfs share'. 40# 4. Verify that the file system is shared. 41# 5. Verify that a shared filesystem cannot be shared again. 42# 6. Verify that share -a succeeds. 43# 44 45verify_runnable "global" 46 47function cleanup 48{ 49 wait 50 for fs in $(seq 0 50) 51 do 52 log_must zfs set sharenfs=off $TESTPOOL/$TESTFS1/$fs 53 log_must zfs set sharenfs=off $TESTPOOL/$TESTFS2/$fs 54 log_must zfs set sharenfs=off $TESTPOOL/$TESTFS3/$fs 55 unshare_fs $TESTPOOL/$TESTFS1/$fs 56 unshare_fs $TESTPOOL/$TESTFS2/$fs 57 unshare_fs $TESTPOOL/$TESTFS3/$fs 58 59 if mounted $TESTPOOL/$TESTFS1/$fs; then 60 log_must zfs unmount $TESTPOOL/$TESTFS1/$fs 61 fi 62 if mounted $TESTPOOL/$TESTFS2/$fs; then 63 log_must zfs unmount $TESTPOOL/$TESTFS2/$fs 64 fi 65 if mounted $TESTPOOL/$TESTFS3/$fs; then 66 log_must zfs unmount $TESTPOOL/$TESTFS3/$fs 67 fi 68 69 datasetexists $TESTPOOL/$TESTFS1/$fs && \ 70 destroy_dataset $TESTPOOL/$TESTFS1/$fs -f 71 datasetexists $TESTPOOL/$TESTFS2/$fs && \ 72 destroy_dataset $TESTPOOL/$TESTFS2/$fs -f 73 datasetexists $TESTPOOL/$TESTFS3/$fs && \ 74 destroy_dataset $TESTPOOL/$TESTFS3/$fs -f 75 done 76 77 log_must zfs share -a 78} 79 80function create_filesystems 81{ 82 for fs in $(seq 0 50) 83 do 84 log_must zfs create -p $TESTPOOL/$TESTFS1/$fs 85 log_must zfs create -p $TESTPOOL/$TESTFS2/$fs 86 log_must zfs create -p $TESTPOOL/$TESTFS3/$fs 87 done 88} 89 90# 91# Main test routine. 92# 93# Given a file system this routine will attempt 94# share the mountpoint and then verify it has been shared. 95# 96function test_share # filesystem 97{ 98 typeset filesystem=$1 99 typeset mntp=$(get_prop mountpoint $filesystem) 100 101 not_shared $mntp || \ 102 log_fail "File system $filesystem is already shared." 103 104 zfs set sharenfs=on $filesystem || \ 105 log_fail "zfs set sharenfs=on $filesystem failed." 106 is_shared $mntp || \ 107 log_fail "File system $filesystem is not shared (set sharenfs)." 108 109 # 110 # Verify 'zfs share' works as well. 111 # 112 zfs unshare $filesystem || \ 113 log_fail "zfs unshare $filesystem failed." 114 is_shared $mntp && \ 115 log_fail "File system $filesystem is still shared." 116 117 zfs share $filesystem || \ 118 log_fail "zfs share $filesystem failed." 119 is_shared $mntp || \ 120 log_fail "file system $filesystem is not shared (zfs share)." 121 122 #log_note "Sharing a shared file system fails." 123 zfs share $filesystem && \ 124 log_fail "zfs share $filesystem did not fail" 125 return 0 126} 127 128# 129# Set the main process id so that we know to capture 130# failures from child processes and allow the parent process 131# to report the failure. 132# 133set_main_pid $$ 134log_assert "Verify that 'zfs share' succeeds as root." 135log_onexit cleanup 136 137create_filesystems 138 139child_pids=() 140for fs in $(seq 0 50) 141do 142 test_share $TESTPOOL/$TESTFS1/$fs & 143 child_pids+=($!) 144 log_note "$TESTPOOL/$TESTFS1/$fs ==> $!" 145 test_share $TESTPOOL/$TESTFS2/$fs & 146 child_pids+=($!) 147 log_note "$TESTPOOL/$TESTFS2/$fs ==> $!" 148 test_share $TESTPOOL/$TESTFS3/$fs & 149 child_pids+=($!) 150 log_note "$TESTPOOL/$TESTFS3/$fs ==> $!" 151done 152wait_for_children "${child_pids[@]}" || 153 log_fail "multithreaded share test failed" 154 155log_note "Verify 'zfs share -a' succeeds." 156 157# 158# Unshare each of the file systems. 159# 160child_pids=() 161for fs in $(seq 0 50) 162do 163 unshare_fs $TESTPOOL/$TESTFS1/$fs & 164 child_pids+=($!) 165 unshare_fs $TESTPOOL/$TESTFS2/$fs & 166 child_pids+=($!) 167 unshare_fs $TESTPOOL/$TESTFS3/$fs & 168 child_pids+=($!) 169done 170wait_for_children "${child_pids[@]}" || 171 log_fail "multithreaded unshare failed" 172 173# 174# Try a zfs share -a and verify all file systems are shared. 175# 176log_must zfs share -a 177 178# 179# We need to unset __ZFS_POOL_EXCLUDE so that we include all file systems 180# in the os-specific zfs exports file.
