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 (consensusbased)

and one asynchronous. We evaluate DynaDisk on

a LAN cluster and compare these two reconfiguration methods.
