'swift-ring-builder <builder_file> finish_increase_partition_power
Finally removes the next_part_power flag. Has to be run after the
swift-object-relinker tool has been used to cleanup old existing data.
A write_ring command is needed to make the change take effect.
USE THIS WITH EXTREME CAUTION
If you increase the partition power and deploy changed rings, you may
introduce unavailability in your cluster. This has an end-user impact. Make
sure you execute required operations to increase the partition power
accurately.'
