Customers using Linux host (mostly RHEL host) using a SAN network for block storage, complain the Linux multipath stack is not resilient to handle non-deterministic storage network behaviors. This has caused many customer move away to non-linux based servers. The intent of the below patch and the prevailing issues are given below. With the below design we are seeing the Linux multipath stack becoming resilient to such network issues. We hope by getting this patch accepted will help in more Linux server adoption that use SAN network. I have already sent the design details to the community in a different mail chain and the details are available in the below link. https://www.redhat.com/archives/dm-devel/2016-December/msg00122.html. Can you please go through the design and send the comments to us.
