[Linux-cluster] Piranha/LVS/Load balancing

I agree that there is a lot of documentation and that it does seem to be 
complete. Searching and finding answers is where things sometimes get messed 
up since it's not often clear what versions or combinations folks are talking 
about when helping each other and ultimately, you if you read and try their 
advise :).

As replied to another list member, this seems to be related to attaching an IP 
to an interface. Thing is, the machines are identical in every way that I know 
of so am not sure why this is suddenly happening. Maybe something is stuck 
somewhere?

No, all of those things are great documents. As I say, it's when one does get 
into trouble, if the answers aren't there, then one has to look on the net and 
possibly end up with new problems based on trying some of the solutions found.

I'll check this one out also. Thanks very much.

I've been doing network stuff since the early 90's so believe me, I don't ask 
unless I've done some researching first, if that's what you mean.

Seems much better to ask live members in a mailing list than to use 
suggestions from the countless sites found when searching for such solutions 
since they could make things worse.
