I wrote a little patch and posted it a few days
ago... I indicated that overflow might be accomplished by adding the overflow
server to the lvs last. This statement is compleatly off the wall
wrong. I'm not really sure why I thought that would work but it won't,
first of all the linked list adds each new instance of a real sever to the start
of the real servers list, not the end like I though. Also it would be
impossible do distingish the overflow server from the real servers in the case
that not all the real servers were busy. I don't know where I got that
idea from but I'm going to blame it on my "bushy eyed youth". In responce
to needing overflow support I'm thinking about implementing "prority groups"
into the lvs code. This would logically group the real severs into
different groups, thoughs with a higher priority group would fillup before those
with a lower grouping. If anybody could comment on this it would be
nice to hear what the rest of you think about overflow
code.
