Ok, Then it should work.
Could you confirm rsync runs successfully when executed manually as below.

1. On master node,
     a) # mkdir /mastermnt
     b) Mount master volume on /mastermnt
     b) # echo "test data" /master/file1
2. On slave node
     a) # mkdir /slavemnt
     b) # Mount slave on /slavemnt
     c) # touch /salvemnt/file1
3. On master node
     a) # cd /mastermnt
     b) # rsync -aR0 --inplace --super --stats --numeric-ids
--no-implied-dirs --existing --xattrs --acls --ignore-missing-args file1 -e
'ssh -oPasswordAuthentication=no -oStrictHostKeyChecking=no  -p 22
-oControlMaster=auto -i /var/lib/glusterd/geo-replication/secret.pem'
root at pgsotc11.png.intel.com:/slavemnt/
4. Check for content sync
     a) cat /slavemnt/file1
