Systems and methods for distributed storage systems using dynamic spreading policies are described. Distributed storage elements may be accessed using various storage paths through hierarchically organized storage system components to store data blocks corresponding to data elements. A higher priority hierarchical spreading policy is selected for determining the storage elements to receive the data blocks. If the first hierarchical spreading policy is determined not to have been met, a lower priority hierarchical spreading policy is selected and the data blocks are stored according to the lower priority hierarchical spreading policy. Data block stored at the lower priority hierarchical spreading policy may automatically be migrated to the higher priority hierarchical spreading policy.
