Ocfs2 users - Jan 2008 - Possibility for networkless installation (for long distance shared storage)

As we have fiber channel, and we have fiber connections, sometimes direct
p-to-p, where we could run it into our fiber channel switch, and share a
disk array over hundreds of feet, to hundreds of miles, but where servers
wouldn't be able to talk via fast enough network connection, does (or will)
ocfs2 support a mode where there is no network connection needed, and all
voting, and cluster "talking" can be done to the block device itself,
including the heartbeat?

 

This would allow me to share files between datacenters.

 

Thanks,

Michael

Ocfs (v1) used to do that, but we moved away from it for Ocfs2 because it
quickly became unusably slow once all the additional locking traffic for
general purpose usage was added.

Michael,

   You might be able to route IP over your FC network. I know that some unixes
do this, but I am not sure on how to do it on Linux.

Regards,
Luis
