Abstract
A system for ensuring availability using volume server sets in a storage environment employing distributed block virtualization includes a plurality of volume servers, one or more volume clients, one or more physical block devices and a volume server manager. The volume server manager may be configured to designate the plurality of volume servers as a volume server set with an associated volume server set management policy, and to verify each volume server in the volume server set has access to storage within each block device. In addition, the volume server manager may be configured to designate a first volume server of the volume server set to aggregate storage within the block devices into a logical volume, to make the logical volume accessible to the volume clients, and to share configuration information about the volume with the other volume servers of the volume server set.
