There have been some discussions about persistence recently but I don't recall
if it was addressing this issue.
May I ask why you have persistence of 6 hours? Seems a long time and sort of
defeats load balancing. I don't know your setup so this may be a naive question.

Waiting for them to expire is not the real problem. The problem is
persistence. Because they can disconnect and reconnect within the
persistence-set limit (6 hrs) and come back to the same server again, even
though weight is set to 0.
What would be handy is if i could temporarily disable persistence, set
weight to 0, wait for them to expire, and then enable persistence again. Or
an option that LVS doesn't look at persistence once a realserver's weight
has been set to 0.
