'remove-brick' process may be in the middle of a file migration.
The process will be fully stopped once the migration of the file is complete.
Please check remove-brick process for completion before doing any further brick related tasks on the volume.




Actual results:
===============
[root@OVM3 ~]# gluster volume remove-brick test1 10.70.35.172:/brick0 status
volume remove-brick status: failed: remove-brick not started.



Expected results:
=================
It should show  status of brick/node.
Message is also confusing - failed and not started!!
