+++ This bug was initially created as a clone of Bug #1512093 +++

Description of problem:

Geo-replication is created, it is active, no errors is reported by CLI and at
glusterfs logs. Start write files to master volume. Use geo-replication detail
status command. Value of "Number of entry Operations pending" is growing after
each synchronization. It never going down except after the replication is
restarted.


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

GlusterFS 3.12.2

How reproducible:
100%

Steps to Reproduce:

1. See the attached file "gluster_geo_repl_bug.txt".

Actual results:

Value of pending entries is not going down after synchronization.


Expected results:

In case of successful synchronization the value has to be "0".


Additional info:

1. See the attached glusterfs log files from the master system
"gluster_logs_master_182.tgz".
2. See the attached glusterfs log files from the slave system
"gluster_logs_slave_183.tgz".

IO from mount stopped while running status command?

Entry count in status changes continuously as long as IO is going on in Master
volume. (Crawl -> Increment count -> Create entries in slave -> Decrement the
count)

This status column is not related to checkpoint. Only if no IO in Master mount
and status shows entry count then it might have some issue.

Problem is reproduced with GlusterFS 3.12.13.

Release 3.12 has been EOLd and this bug was still found to be in the NEW state,
hence moving the version to mainline, to triage the same and take appropriate
actions.

Will need to check with the assignee or component maintainer, which is Kotresh
in both cases. @Kotresh request an update here? Thanks.
