Hello, Sorry to bother you, but I wanted to thank you for your update on the multipath.conf.default. I'm trying to get my MD3000 to work properly but had some troubles with it. I think your example will help me out! But I do have one question about your update. It says to use /sbin/mpath_prio_tcp but I don't have this on my system. I do have the latest version 4.5.8 but can't find it. Any tip would be greatly appreciated!!
