Multipath and nbd
I am at the design stage for a new server. That's when you try to convince a client that they have an unfavorable ratio of requirements to budget. I am thinking a raid-1, with a mirror to an nbd device running write-mostly. I will have redundant network paths to the other machine, one via a dedicated cable and P-t-P connection, and the other via a switch going to the general internal network.
Am I going into deep waters to try and do something helpful with multipath features here, or should I stick to a network only solution, and give the switched route a higher metric to force traffic through the dedicated link?
