Description Raghavendra G 2013-07-24 05:54:59 UTC

+++ This bug was initially created as a clone of Bug #979910 +++

Description of problem:
 with readdirplus support, kernel may not send lookup before
    a path based fop. Though readdirplus of each xlators do
    some things done in lookup, its not complete enough to replace
    a lookup. Hence its necessary that a lookup should be sent
    before we go ahead with path based fop.


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

How reproducible:
consistently

Steps to Reproduce:
conifiguration: Two node replicate, fuse with readdirplus support (RHEL 6.4)

1. mount a glusterfs volume with existing data.
2. start copying from glusterfs mountpoint (it doesn't matter whether destination is glusterfs or not).
3. kill first (0th) brick of afr.

Actual results:
cp fails with ENOTCONN errors

Expected results:
cp shouldn't fail since 2nd brick is up and running.

This bug is actually important for supporting readdirplus support in glusterfs, which is needed for performance.
