Description Shwetha Panduranga 2012-03-26 08:50:29 EDT
Description of problem
when replace-brick is performed, a glusterfs client process is started to migrate the data. executing "mount" command is displaying the replace-brick started glusterfs process also. 

This client process should not be displayed in the mount output as it is internal process started by replace-brick.  

Version-Release number of selected component (if applicable):
mainline

How reproducible:
often

Steps to Reproduce:
1.create a volume. start volume
2.perform replace-brick <old_brick> <new_brick>
3.execute "mount" command on the storage node where replace-brick is started. 
  
Actual results:
