Create two filesystem fs & fs1, and create two test files for them. 37# 2. Unmount fs1 and set mountpoint property is identical to fs. 38# 3. Verify 'zfs mount -O' will make the underlying filesystem fs 39# inaccessible. 40# 41 42function cleanup 43{ 44 ! ismounted $fs && log_must $ZFS mount $fs 45 46 if datasetexists $fs1; then 47 log_must $ZFS destroy $fs1 48 fi 49 50 if [[ -f $testfile ]]; then 51 log_must $RM -f $testfile 52 fi 53} 54 55log_assert "Verify 'zfs mount -O' will override existing mount point." 56log_onexit cleanup 57 58fs=$TESTPOOL/$TESTFS; fs1=$TESTPOOL/$TESTFS1 59 60cleanup 61 62# Get the original mountpoint of $fs and $fs1 63mntpnt=$(get_prop mountpoint $fs) 64log_must $ZFS create $fs1 65mntpnt1=$(get_prop mountpoint $fs1) 66 67testfile=$mntpnt/$TESTFILE0; testfile1=$mntpnt1/$TESTFILE1 68log_must $MKFILE 1M $testfile $testfile1 69 70log_must $ZFS unmount $fs1 71log_must $ZFS set mountpoint=$mntpnt $fs1 72log_mustnot $ZFS mount $fs1 73log_must $ZFS mount -O $fs1 74 75# Create new file in override mountpoint 76log_must $MKFILE 1M $mntpnt/$TESTFILE2 77 78# Verify the underlying file system inaccessible 79log_mustnot $LS $testfile 80log_must $LS $mntpnt/$TESTFILE1 $mntpnt/$TESTFILE2 81 82# Verify $TESTFILE2 was created in $fs1, rather then $fs 83log_must $ZFS unmount $fs1 84log_must $ZFS set mountpoint=$mntpnt1 $fs1 85log_must $ZFS mount $fs1 86log_must $LS $testfile1 $mntpnt1/$TESTFILE2 87 88# Verify $TESTFILE2 was not created in $fs, and $fs is accessable again. 89log_mustnot $LS $mntpnt/$TESTFILE2 90log_must $LS $testfile 91 92log_pass "Verify 'zfs mount -O' override mount point passed." 93
