            Bug ID: 1246082
           Summary: sharding - Populate the aggregated ia_size and
                    ia_blocks before unwinding (f)setattr to upper layers
           Product: GlusterFS
           Version: mainline
         Component: sharding
          Keywords: Triaged
          Assignee: bugs at gluster.org

Description of problem:
Sharding translator does not aggregate ia_size and ia_blocks in the cbks of
(f)setattr. And fuse copies out poststat into the fuse output header before
writing the response to /dev/fuse. This was causing issues with OS installation
on vm images with sharded volumes.

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


How reproducible:


Steps to Reproduce:
1. Create a dis-rep volume with sharding enabled and also all the options that
need to be set which are documented at
http://www.gluster.org/community/documentation/index.php/Libgfapi_with_qemu_libvirt.
2. Create a vm image on the volume.
3. Try to install (any) OS on this newly created image using virt-install CLI.
4. Open the UI on virt-manager and resume installation.
5. The application fails to recognise the virtio disk that is associated with
the image.

Actual results:


Expected results:
