Hi, The following patches add the following 2 dynamic load balancers to request-based dm-multipath: o queue-length oriented dynamic load balancer, dm-queue-length. o service-time oriented dynamic load balancer, dm-service-time. This patch-set is not ready for inclusion to the upstream kernel, but I'm posting now to hear comments from multipath related people. Any comments are welcome. This patch-set can be applied on top of 2.6.27-rc6 + Alasdair's linux-next patches below + request-based dm patches(*). dm-mpath-use-more-error-codes.patch dm-mpath-remove-is_active-from-struct-dm_path.patch (*) http://lkml.org/lkml/2008/9/12/100 Summary of the patch-set: 1/4: dm-mpath: add a path-selector interface 2/4: dm-mpath: add queue-length oriented dynamic load balancer (dlb) 3/4: dm-mpath: interface change for service-time oriented dlb 4/4: dm-mpath: add service-time oriented dynamic load balancer (dlb) Thanks, Kiyoshi Ueda -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
