Description Barak 2014-04-02 22:49:29 UTC

+++ This bug was initially created as a clone of Bug #1083645 +++

Description of problem:
Currently we use in vdsm oop.
We want to use instead the python bindings for ioprocess while maintaining the same behavior on NFS storage side when performing IO ops.

Version-Release number of selected component (if applicable):
3.5
