In order to log rotate, we need to stop the deamon accessing the log file 
and them rename it right? I have removed the log file using rm command to 
check whether it will release the space, but even after the file removal, 
my /var partition is still full. 

So, do I have to stop MDS deamon and then remove the log file ? i am not 
finding any command through which i can stop MDS on node. Can you please
let me know how i can safely stop the MDS and then start it back ?

Thanks
