At Risk Tools

Registered by gholt on 2011-04-23

When a drive fails, all ring partitions that were on that drive immediately have only 2 copies left in the cluster (assuming 3 replicas here). As the replicators on the servers containing those other copies get to it, they will make an extra handoff copy to get back to 3 copies in the cluster.

Replication cycles can take a while though, so we'd like to have some tools to make this happen faster.

1) A tool that will list the ring partitions for a given device or a list of common ring partitions for a set of devices (for multi-device failures).

2) A tool to immediately start extra replication of a list of partitions from 1).

Part one was done and is in swift-ring-builder. Part two has yet to be done, but isn't being clamored for at the moment at least.
