Hi,
this shows that the TCP SYN is comming into the director but is not forwarded
to the real servers in the background.
In your first mail you showed the output of ipvs -L -n.
root@lb1:/etc/ha.d# ipvsadm -L -n
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 192.168.1.243:3306 wrr
-> 192.168.1.246:3306 Route 0 0 0
-> 192.168.1.247:3306 Route 0 0 0
Both real servers have the weight of "0" wich means "dead" or "please do not
forward packets to this real server". That explains, why the TCP SYN is not
forwarded to the real servers.
Have you checked you log files why ipvs is setting weight to "0". Perhaps the
tests fail? Does the DB ldirectordb (according to the config) exists? Can you
manually open the database and do the test?
