Description Sean Cohen 2015-08-26 13:46:36 EDT
Problem Description

The ring power determines the partition to which a resource (account, container or object) is mapped. The partition is included in the path under which the resource is stored in a backend filesystem. Changing the partition power therefore requires relocating resources to new paths in backend filesystems.

In a heavily populated cluster a relocation process could be time-consuming and so to avoid down-time it is desirable to relocate resources while the cluster is still operating. However, it is necessary to do so without (temporary) loss of access to data and without compromising the performance of processes such as replication and auditing.
