Create two filesystem fs & fs1, and create two test files for them. 41# 2. Unmount fs1 and set mountpoint property is identical to fs. 42# 3. Verify 'zfs mount -O' will make the underlying filesystem fs 43# inaccessible. 44# 45# TESTABILITY: explicit 46# 47# TEST_AUTOMATION_LEVEL: automated 48# 49# CODING_STATUS: COMPLETED (2006-08-02) 50# 51# __stc_assertion_end 52# 53################################################################################ 54 55function cleanup 56{ 57 ! ismounted $fs && log_must $ZFS mount $fs 58 59 if datasetexists $fs1; then 60 log_must $ZFS destroy $fs1 61 fi 62 63 if [[ -f $testfile ]]; then 64 log_must $RM -f $testfile 65 fi 66} 67 68log_assert "Verify 'zfs mount -O' will override existing mount point." 69log_onexit cleanup 70 71fs=$TESTPOOL/$TESTFS; fs1=$TESTPOOL/$TESTFS1 72 73cleanup 74 75# Get the original mountpoint of $fs and $fs1 76mntpnt=$(get_prop mountpoint $fs) 77log_must $ZFS create $fs1 78mntpnt1=$(get_prop mountpoint $fs1) 79 80testfile=$mntpnt/$TESTFILE0; testfile1=$mntpnt1/$TESTFILE1 81log_must $MKFILE 1M $testfile $testfile1 82 83log_must $ZFS unmount $fs1 84log_must $ZFS set mountpoint=$mntpnt $fs1 85log_must $ZFS mount $fs1 86 87# Create new file in override mountpoint 88log_must $MKFILE 1M $mntpnt/$TESTFILE2 89 90# Verify the underlying file system inaccessible 91log_mustnot $LS $testfile 92log_must $LS $mntpnt/$TESTFILE1 $mntpnt/$TESTFILE2 93 94# Verify $TESTFILE2 was created in $fs1, rather then $fs 95log_must $ZFS unmount $fs1 96log_must $ZFS set mountpoint=$mntpnt1 $fs1 97log_must $ZFS mount $fs1 98log_must $LS $testfile1 $mntpnt1/$TESTFILE2 99 100# Verify $TESTFILE2 was not created in $fs, and $fs is accessible again. 101log_mustnot $LS $mntpnt/$TESTFILE2 102log_must $LS $testfile 103 104log_pass "Verify 'zfs mount -O' override mount point passed." 105
