Manish,

I know the mount command reports the filesystem r/w, but your results
make it look like the filesystem is readonly.

Did you verify you can manually write to the filesystem?

I've seen mount lie before.  (It's not really a lie.  It reports what
was passed on the mount command-line I believe, not the actually
functionality of the filesystem.)

Good Luck
Greg
