Multipath and nbd

Multipath and nbd

[Bill Davidsen]

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?
