Before start copying, <br>
- Enable changelog in Master volume, using `gluster volume set
<volname> changelog.changelog on`<br>
- Record the Timestamp. This is required to set the marking once
Geo-rep session is created.<br>
- Gluster Geo-replication replicates the data with same GFID in
target, so if we are copying data manually we should ensure that
GFIDs remains same and properly linked as hardlinks in the
.glusterfs directory.

After creating the Geo-replication session it will try to start from
the beginning, to avoid that set the marking in each bricks before
starting Geo-replication saying till this time data is synced to
Slave. Once started, it will start from this timestamp.(I can
provide script for the same)
