Sort of. You've set the server to quiesce (weight=0; whether you or ldirectord did this is of no concern). Existing connections - those prior to TCP FIN/RST or those within the persistence timeout - continue to be sent to the quiesced realserver. To change this behaviour, set the sysctls: /proc/sys/net/ipv4/vs/expire_nodest_conn = 1 /proc/sys/net/ipv4/vs/expire_quiescent_template = 1 The first removes all persistent entries from realservers which have been removed from the VS, the second removes all persistent entries from realservers which have been quiesced in a given VS.
