Description SATHEESARAN 2013-08-27 10:24:15 UTC

Description of problem:
=======================
While enabling quota using, 'gluster volume set <volname> quota enable' doesn't
started quotad

Version-Release number of selected component (if applicable):
=============================================================
glusterfs-3.4.0.20rhsquota5-1.el6rhs.x86_64

How reproducible:
=================
Always

Steps to Reproduce:
===================
1. Create a 2X2 distributed replicate volume
(i.e) gluster volume create <vol-name> replica 2 <brick1> .. <brick4>

2. Start the volume
(i.e) gluster volume start <vol-name>

3. Enable quota using 'volume set' command
(i.e) gluster volume set <vol-name> quota on

Actual results:
===============
quotad should start running

Expected results:
=================
quotad was not running.

Additional info:
================
I used 'gluster volume quota <vol-name> enable' to enable quota on a volume
That worked fine. It started 'quotad'. I expect the same, when I enable
quota through 'gluster volume set'

In this case, when I stop and start the volume, I could see 'quotad' coming up.

Comment 1 krishnan parthasarathi 2013-09-02 06:08:09 UTC

The volume-set interface is *not* the way to enable quota, in the current design. 
#gluster volume quota VOLNAME enable
is the way to enable to quota on VOLNAME.

Quotad would be running if and only if, there exists at least one started volume, that has quota enabled.

Closing this as not a bug.
