Description Krutika Dhananjay 2015-07-23 12:36:09 UTC
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:

Fix for this BZ is already present in a GlusterFS release. You can find clone of this BZ, fixed in a GlusterFS release and closed. Hence closing this mainline BZ as well.

Comment 4 Niels de Vos 2016-06-16 13:26:51 UTC
This bug is getting closed because a release has been made available that should address the reported issue. In case the problem is still not fixed with glusterfs-3.8.0, please open a new bug report.

glusterfs-3.8.0 has been announced on the Gluster mailinglists [1], packages for several distributions should become available in the near future. Keep an eye on the Gluster Users mailinglist [2] and the update infrastructure for your distribution.
