We consider data-centric distributed storage, where storagenodes are directly attached to the network. We present DynaDisk, the first read/write storage system that allows clients to add and remove storage devices in a completely decentralized manner, and without stopping ongoing read/write operations. DynaDisk supports two alternative approaches to reconfiguration, one partially synchronous (consensus based) and one asynchronous. We evaluate DynaDisk on a LAN cluster and compare these two reconfiguration methods.
