So you are trying to decrease the number of PGs.
Now, I'm not sure if that is supported. But why would you want to do this?

Hi Ceph Community ,
I am facing problem while I am explicitly trying to set
"pg_number" of "data" pool.

Could you show us the output of the following command?
$ ceph osd dump -o -|grep pg_num
It seems like you are trying to decrease the number of PGs?
root@third-virtual-machine:~# ceph osd pool get data pg_num
2012-08-29 15:09:04.788365 mon <- [osd,pool,get,data,pg_num]
2012-08-29 15:09:04.788833 mon0 -> 'PG_NUM: 200' (0)

Why is it not working to set pg_number to 100. The cmd is executed
while ceph is running.
(ceph v. 0.36, ubuntu 11.10)
I recommend upgrading to Ubuntu 12.04.1 with Ceph 0.48.1
