Abstract
Techniques are provided for increasing resiliency of IO operations to network interruptions. One method comprises, in response to a failure of a given IO operation on a first path between at least one initiator of a host device and at least one storage target of a storage volume of a distributed storage system, resending the given IO operation on a second path between the at least one initiator and the at least one storage target; and, in response to a completion of the given IO operation on a given one of the first path and the second path, initiating a remapping of the storage volume. The remapping of the storage volume may comprise unmapping the storage volume and mapping the storage volume. One or more IO operations having an older generation number than the generation number of the storage volume may be discarded.
