Description Rachana Patel 2014-06-27 14:26:36 UTC

Description of problem:
=======================
cause of any reasons if Directory has been self healed, log has below messages where 0 GFIDs are dumped in the log rather than the actual GFID of the directory.

:[2014-06-25 08:52:50.339861] I [dht-layout.c:663:dht_layout_normalize] 0-snap-dht: Found anomalies in /zile (gfid = 00000000-0000-0000-0000-000000000000). Holes=1 overlaps=0




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

1.Create and mount Distributed Volume
2. Create Directories from mount point and make sure It is not created on all up sub-volumes.
3. send lookup from another mount point.
4. check logs for self-healed Directory 0 GFIDs are dumped rather than actual

Actual results:
===============

Verified this bug in glusterfs-3.7.9-1.el7rhgs.x86_64

Proper gfid is updated in the logs instead of mere 0.

Marking this bug as verified.
