The BB8 daemon is responsible for rebalancing data between RSEs.
options:
  -h, --help            show this help message and exit
  --rse RSE             RSE to rebalance. Can be either a RSE or RSE
                        expression.
  --bytes BYTES         Number of bytes to expected to be rebalanced. It is a
                        goal without guarantees
  --run-once            One iteration only
  --sleep-time SLEEP_TIME
                        Concurrency control: thread sleep time after each
                        chunk of work
  --threads THREADS     Concurrency control: total number of threads for this
                        process
  --dry-run             Only run in dry-run mode
  --exclude-expression EXCLUDE_EXPRESSION
                        Exclude these rse_expression from being destinations
  --comment COMMENT     Add a comment to the new rules
  --force-expression FORCE_EXPRESSION
                        For this rse_expression for rebalanced rules instead
                        of letting BB8 decide
  --decommission        Run BB8 in decommission mode
  --priority PRIORITY   Priority for the newly created rules
  --source-replica-expression SOURCE_REPLICA_EXPRESSION
                        Source replica expression for the newly created rules
