Make sure that the ZFS filesystem is mounted. 46# 2. Change directory to that given mountpoint. 47# 3. Unmount the file system using the various combinations. 48# - Without force option. (FAILED) 49# - With force option. (PASS) 50# 4. Unmount the mountpoint using the various combinations. 51# - Without force option. (FAILED) 52# - With force option. (PASS) 53# 5. Verify the above expected results of the filesystem|mountpoint. 54# 55 56verify_runnable "both" 57 58 59set -A cmd "umount" "unmount" 60set -A options "" "-f" 61set -A dev "$TESTPOOL/$TESTFS" "$TESTDIR" 62 63function do_unmount_multiple #options #expect 64{ 65 typeset opt=$1 66 typeset -i expect=${2-0} 67 68 typeset -i i=0 69 typeset -i j=0 70 71 while (( i < ${#cmd[*]} )); do 72 j=0 73 while (( j < ${#dev[*]} )); do 74 mounted ${dev[j]} || \ 75 log_must zfs $mountcmd ${dev[0]} 76 77 cd $TESTDIR || \ 78 log_unresolved "Unable change dir to $TESTDIR" 79 80 do_unmount "${cmd[i]}" "$opt" \ 81 "${dev[j]}" $expect 82 83 cleanup 84 85 ((j = j + 1)) 86 done 87 88 ((i = i + 1)) 89 done 90} 91 92log_assert "Verify that 'zfs $unmountcmd <filesystem|mountpoint>' " \ 93 "with a filesystem which mountpoint is currently in use " \ 94 "will fail with return code 1, and forcefully will succeeds as root." 95 96log_onexit cleanup 97 98cwd=$PWD 99 100typeset -i i=0 101 102while (( i < ${#options[*]} )); do 103 if [[ ${options[i]} == "-f" ]]; then 104 do_unmount_multiple "${options[i]}" 105 else 106 do_unmount_multiple "${options[i]}" 1 107 fi 108 ((i = i + 1)) 109done 110 111log_pass "'zfs $unmountcmd <filesystem|mountpoint>' " \ 112 "with a filesystem which mountpoint is currently in use " \ 113 "will fail with return code 1, and forcefully will succeeds as root." 114
