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 {0..50} 51 do 52 for pfs in $TESTFS1 $TESTFS2 $TESTFS3 53 do 54 log_must zfs set sharenfs=off $TESTPOOL/$pfs/$fs 55 unshare_fs $TESTPOOL/$pfs/$fs 56 57 if mounted $TESTPOOL/$pfs/$fs; then 58 log_must zfs unmount $TESTPOOL/$pfs/$fs 59 fi 60 61 datasetexists $TESTPOOL/$pfs/$fs && \ 62 destroy_dataset $TESTPOOL/$pfs/$fs -f 63 done 64 done 65 66 log_must zfs share -a 67} 68 69function create_filesystems 70{ 71 for fs in {0..50} 72 do 73 log_must zfs create -p $TESTPOOL/$TESTFS1/$fs 74 log_must zfs create -p $TESTPOOL/$TESTFS2/$fs 75 log_must zfs create -p $TESTPOOL/$TESTFS3/$fs 76 done 77} 78 79function sub_fail 80{ 81 log_note $$: "$@" 82 exit 1 83} 84 85# 86# Main test routine. 87# 88# Given a file system this routine will attempt 89# share the mountpoint and then verify it has been shared. 90# 91function test_share # filesystem 92{ 93 typeset filesystem=$1 94 typeset mntp=$(get_prop mountpoint $filesystem) 95 96 not_shared $mntp || \ 97 sub_fail "File system $filesystem is already shared." 98 99 zfs set sharenfs=on $filesystem || \ 100 sub_fail "zfs set sharenfs=on $filesystem failed." 101 is_shared $mntp || \ 102 sub_fail "File system $filesystem is not shared (set sharenfs)." 103 104 # 105 # Verify 'zfs share' works as well. 106 # 107 zfs unshare $filesystem || \ 108 sub_fail "zfs unshare $filesystem failed." 109 is_shared $mntp && \ 110 sub_fail "File system $filesystem is still shared." 111 112 113 zfs share $filesystem || \ 114 sub_fail "zfs share $filesystem failed." 115 is_shared $mntp || \ 116 sub_fail "file system $filesystem is not shared (zfs share)." 117 118 119 #log_note "Sharing a shared file system fails." 120 zfs share $filesystem && \ 121 sub_fail "zfs share $filesystem did not fail" 122 123 return 0 124} 125 126function unshare_fs_nolog 127{ 128 typeset fs=$1 129 130 if is_shared $fs || is_shared_smb $fs; then 131 zfs unshare $fs || 132 sub_fail "zfs unshare $fs: $?" 133 fi 134} 135 136# 137# Set the main process id so that we know to capture 138# failures from child processes and allow the parent process 139# to report the failure. 140# 141set_main_pid $$ 142log_assert "Verify that 'zfs share' succeeds as root." 143log_onexit cleanup 144 145create_filesystems 146 147child_pids=() 148for fs in {0..50} 149do 150 for pfs in $TESTFS1 $TESTFS2 $TESTFS3 151 do 152 test_share $TESTPOOL/$pfs/$fs & 153 child_pids+=($!) 154 log_note "$TESTPOOL/$pfs/$fs ==> $!" 155 done 156done 157log_must wait_for_children "${child_pids[@]}" 158 159log_note "Verify 'zfs share -a' succeeds." 160 161# 162# Unshare each of the file systems. 163# 164child_pids=() 165for fs in {0..50} 166do 167 for pfs in $TESTFS1 $TESTFS2 $TESTFS3 168 do 169 unshare_fs_nolog $TESTPOOL/$pfs/$fs & 170 child_pids+=($!) 171 log_note "$TESTPOOL/$pfs/$fs (unshare) ==> $!" 172 done 173done 174log_must wait_for_children "${child_pids[@]}" 175 176# 177# Try a zfs share -a and verify all file systems are shared. 178# 179log_must zfs share -a 180 181# 182# We need to unset __ZFS_POOL_EXCLUDE so that we include all file systems 183# in the os-specific zfs exports file.
