Techniques are disclosed for storage resource resynchronization using pending IO requests. For example, a method includes, upon detecting a failed network: quiescing IO activity in progress; identifying storage resources and associated pending IO requests; for each storage resource: creating a first snapshot of the storage resource; for each pending IO request, marking blocks specified by the pending IO request as modified; unquiescing the quiesced IO activity; upon detecting the network has been restored: creating a second snapshot of each storage resource; remote mirroring, to the destination, a copy of differences of each source storage resource to the destination storage resource, wherein the differences are identified by comparing the first and the second snapshot; transmitting a request for the destination to create a third snapshot comprising a snapshot of each destination storage resource; and triggering the destination to process the third snapshot to identify storage resources based on the differences.
