[Ocfs2-devel] using ethernet instead of TCP

[James Harper]

Has anyone considered having the option of using Ethernet instead of TCP
for inter-node communications? Such a feature would be useful for me as
I'd like to use the same Ethernet segment for inter-node communication
as I run AoE over (much less chance of a split brain), but I don't
currently run IP on that segment. Also, running ocfs2 as the root
filesystem would be easier (I've asked on -users if this is a good idea,
as discussion of that aspect probably isn't appropriate to -devel) as IP
wouldn't need to be started before bringing the root filesystem online.

Obviously it's going to limit the cluster to the one lan segment, and
you get a lot of stuff 'for free' with TCP that would have to be written
for ocfs2 to use Ethernet (but I don't know how much the inter-node
stuff actually makes use of it), so it might be too much work for too
little gain...

Thanks
