more explanation : yuo can see that /pacrd18 is showing 05 in bdf , but i can trnsverse the directory in it , also this FS was 100% full before reboot.There is no process holding the space also

pwctest:/#fuser -cu /pcard18
/pcard18: 5708c(techsup2)

pwctest:/#

there is less than 0,5% data in the file system.
it can be that the data is in other filesystems:
bdf |grep /pcard18
to see if there are file systems under /pcard18

you can use du to check the real size:
du -ks /pcard18

to check everyting is mounted use:
mountall
if you are getting errors please post them fore more help.
to check it is a cluster please run
cmviewcl (as root)
and post the output form more help...

>you can see that /pacrd18 is showing 0% in bdf

bdf is correctly showing you that it is .3% if you calculate the percentage:
p 100 * 32137.0 / 10485760
$3 = 0.30648231506347656

So you are using only a trivial 32 Mb, you might as well ignore it. ;-)
