            Bug ID: 1218170
           Summary: [Quota] : To have a separate quota.conf file for inode
                    quota.
           Product: GlusterFS

         Component: quota

+++ This bug was initially created as a clone of Bug #1202244 +++

Description of problem:
Currently we maintain the quota configuration in a file called
quota.conf which is present in /var/lib/gluster/vols/<volname>

With introduction of inode quota, we have to save the configuration
related to inode quota in a file too. If we have the same file to
service both existing quota and inode quota we might end up in the
below mentioned problem:

* quota conf is a place holder to save gfid of the directory where
  quota limit is set.
* The problem occurs when we try to remove a limit on some directory.
  As we now have two types of quota we cant distinguish between the
  type by having gfid alone.

Possible solution:
1) Currently we maintain a 16byte gfid, we can save 1 byte extra
   along with gfid that to distinguish b/w existing quota and inode quota
2) TO have a separate quota.conf file altogether for inode quotas

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

How reproducible:
1/1

Steps to Reproduce:
1. Set a usage limit on directory " gluster volume quota <volname> limit-usage
<directory> <size>
2. Set a inode quota limit on directory "gluster volume quota <volname>
limit-objects <directory> <limit>
3. remove the limit on usage on directory
4. test the inode quota list "gluster volume quota vol1 list-objects

Actual results:
inode quota is also removed if we remove usage quota.

Expected results:
inode quota should not be effected by usage quota.
