[Linux-cluster] Multiple Logical Volumes

Ok, so the actual IP's I would have otherwise installed on each server.

My setup includes multiple storage devices. I can either have multiple devices 
or I can create one large filesystem for all of the nodes in this cluster. 
Which do you think is best since I can keep adding or taking from a volume 
group.

As in server images and such? This I have to read about, the whole idea is new 
to me as of this morning :).

My machines share CDROM/Floppy so can't boot from those automatically. I do 
have network boot on each server however and of course, I'd like not to have 
to use any drives on any of the blades. Then I could put more into the central 
storage.

I'm using fibre channel so all of the nodes see the storage as their own.

Thanks for all this info, I'll continue looking for more and build one of 
these. I am sure it's exactly what I need over having to build multiple 
machines all the time.
