Send modifications to the cluster layout. These modifications will be included in the staged role changes, visible in subsequent calls of GET /GetClusterHealth. Once the set of staged changes is satisfactory, the user may call POST /ApplyClusterLayout to apply the changed changes, or POST /RevertClusterLayout to clear all of the staged changes in the layout.

Setting the capacity to null will configure the node as a gateway. Otherwise, capacity must be now set in bytes (before Garage 0.9 it was arbitrary weights). For example to declare 100GB, you must set capacity: 100000000000.

Garage uses internally the International System of Units (SI), it assumes that 1kB = 1000 bytes, and displays storage as kB, MB, GB (and not KiB, MiB, GiB that assume 1KiB = 1024 bytes).
