Abstract: A method, a computing device, and a non-transitory machine-readable medium for performing a multipath selection based on a determined quality of service for the paths. An example method includes a host computing device periodically polling a storage system for path information including an indication of a recommended storage controller. The host computing device periodically determines a quality of service information corresponding to a plurality of paths between the host computing device and a storage volume of the storage system, where at least one of the plurality of paths including the recommended storage controller. The host computing device identifies a fault corresponding to a path of the plurality of paths that routes I/O from the host computing device to the storage volume. The host computing device re-routes the I/O from the path to a different path of the plurality of paths, where the different path is selected for the re-routing based on the quality of service information and the path information.
