Description jhoffer 2013-07-24 18:39:53 UTC

Description of problem:
When a gluster volume is mounted on a Windows client as a network drive letter, the capacity displayed by Windows is incorrect.  Each 1GB brick shows 4TB on Windows, 10GB bricks show 40TB.

Version-Release number of selected component (if applicable):
Windows7 client
glusterfs 3.4.0.12rhs.beta6 built on Jul 23 2013 16:20:03
RHS-2.1-20130724.n.0-RHS-x86_64-DVD1.iso

How reproducible:
Capacity is displayed by Windows Explorer 

Steps to Reproduce:
1. Create Gluster volume
2. Mount as network drive letter on Windows client (not just browse to share)
3. 
  
Actual results:
Network drive letter claims to be 40,000 times larger than it is.

Expected results:
Drive letter should report actual capacity.

Additional info:
Setting quota on volume does not seem to affect displayed capacity. Started with two 10GB bricks and saw ~80TB, added two more 10GB bricks and saw ~160TB.

Verified with version :
samba-glusterfs-3.6.9-159.1.el6rhs.x86_64
glusterfs-3.4.0.19rhs-2.el6rhs.x86_64

After doing a mount of gluster volume on windows the volume capacity shown by windows is correct and is same as the actual capacity.

Tried with adding bricks and it shows the correct capacity in this case as well.
