Systems and methods for performing snapshots in a storage environment employing distributed block virtualization. In one embodiment, the system may include a volume server, a first and a second host computer system, and a plurality of physical block devices. The volume server may be configured to aggregate storage in the plurality of physical block devices into a plurality of logical volumes, where a particular logical volume includes storage from at least two physical block devices. The volume server may further be configured to make a first and a second subset of the logical volumes available to the first and second host computer systems for input/output, respectively. The first subset and the second subset may be at least partially nonoverlapping, and a second logical volume may be configured to store a snapshot of data stored in a first logical volume logical volume.
