PERFORMANCE IMPLICATIONS

SUBCOMMAND
----------
*cancel* <path>::
-cancel running or paused balance, the command will block and wait until the
-actually processed blockgroup is finished
+cancels a running or paused balance, the command will block and wait until the

*pause* <path>::
pause running balance operation, this will store the state of the balance
