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!!
Sander
