System and method for resynchronizing mirrored volumes in a storage system. According to one embodiment, a system may include a first volume located at a primary site and associated with a first storage management device, and a second volume located at a secondary site and associated with a second storage management device, where the secondary site is coupled to the primary site via a data link, and where the second volume is configured as a mirror of the first volume. The first storage management device may be configured to convey to the second storage management device an indication of a data block written to the first volume subsequent to a failure of the data link. Dependent upon the indication, the second storage management device may be configured to create a snapshot of the data block as stored on the second volume prior to resynchronization of the data block.
