Remove inhibit_on_failure.
That keeps the server in the pool but with weight 0, meaning no *new*
connections go to it. Existing persistent connections remain.
Alternatively, if you don't want to do that, set the sysctl
net.ipv4.vs.expire_quiescent_template to 1, and keep inhibit_on_failure.
Both options are in effect synonyms, meaning in both cases that the
persistence templates are removed for the VS in question when either it
is removed from the pool (removing inhibit_on_failure) or quiesced
(weight set to 0).
