Description Kotresh HR 2017-02-16 10:35:34 UTC

+++ This bug was initially created as a clone of Bug #1422760 +++

Description of problem:
When geo-rep session is deleted with the option reset-sync-time and the data on slave is deleted, the recreation of session with same old slave volume is not syncing data from master to slave. It is observed, it happens only if the data to slave is synced via xsync before deletion of the geo-rep session. Only entries under root are being synced.

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

How reproducible:
Always

Steps to Reproduce:
1.  Create geo-rep session between 'master' and 'slave' volume.
2.  Set change-detector to 'xsync'
3.  Create data on master and let it sync to slave
4.  Delete geo-rep session with 'reset-rsync-time'
5.  Delete data on slave volume.
6.  Recreate geo-rep session with same master and slave volume
7.  Start the geo-rep

Actual results:
Only first level entries under root are being synced and rest are not synced.

Expected results:
It is expected all the data from master is synced again.
