Description of problem:
With a data set having files and directories, on a 6 node setup triggered rebalance. Rebalance on 3 of 6 nodes completed in 7 minutes. On the other nodes rebalance is running for more than 5 hrs and is still running.
Seems like rebalance process is not going to end. In rebalance logs I am not seeing any fix-layout changes or file migration messages and in rebalance status there is no change in the values of rebalance files, size, scanned, failures, skipped since 5hrs.
I have left the system in the same state and can be used for live debugging.

Reporting at first occurrence
Steps to Reproduce:
Not sure on the exact reproducer but below steps lead to this situation.
1) Create a x3 volume and start it.
2) FUSE mount on multiple clients
3) From mount point, create files and directories.
4) From one client start renaming the data set created in 3 and from other clients start lookups.
5) Now add-bricks and start rebalance with force option.
6) Wait till the rebalance completes.
Rebalance on few nodes doesn't seem to complete .
Rebalance should complete without any issues.
Verified this BZ on glusterfs version: 3.12.2-13.el7rhgs.x86_64. Ran the tests mentioned in the description and Comment 9.
Did not see rebalance hang, moving this BZ to Verified state.
