Hi all, an error in ftruncate04 test is found,
The problem I see is due to incorrect parsing
of `df` command output:
<<<test_start>>>
tag=ftruncate04 stime=1284729392
cmdline="ftruncate04.sh"
contacts=""
analysis=exit
<<<test_output>>>
DEV: /dev/mapper/vg_rhel6beta-lv_root
MOUNT_POINT: /dev/mapper/vg_rhel6beta-lv_root
FLAG: rw,mand
ftruncate04 1 TPASS : Test passed.
mount: you must specify the filesystem type
ftruncate04.sh : ERROR : mounting /dev/mapper/vg_rhel6beta-lv_root
remount,rw,mand failed

<<<execution_status>>>
initiation_status="ok"

cutime=1 cstime=7
<<<test_end>>>
# mount | head -1
/dev/mapper/vg_rhel6beta-lv_root on / type ext4 (rw,mand)
# df .

/dev/mapper/vg_rhel6beta-lv_root
2523808 2436384 0 100% /
A patch is attached to fix this problem. After applied the patch,
the failure gone:
<<<test_start>>>
tag=ftruncate04 stime=1284729277
cmdline="ftruncate04.sh"
contacts=""
analysis=exit
<<<test_output>>>
DEV: /dev/mapper/vg_rhel6beta-lv_root

cutime=1 cstime=9
<<<test_end>>>
# mount | head -1
/dev/mapper/vg_rhel6beta-lv_root on / type ext4 (rw)
# df -P .
Filesystem 1024-blocks Used Available Capacity Mounted on
/dev/mapper/vg_rhel6beta-lv_root 2523808 2436380 0 100% /
So the test without the patch leaves the system in inconsistent state
(mand option is kept for the filesystem) which is bad.
