[lvs-users] sync daemon timeout with stickyness

[David Coulson]

I have a pretty simple ipvs config.

Prot LocalAddress:Port Scheduler Flags
  -> RemoteAddress:Port           Forward Weight ActiveConn InActConn
TCP  103.200.100.1:80 wrr persistent 1800
  -> 103.75.25.85:80              Route   1      0          0        
  -> 103.75.25.76:80              Route   1      0          0        
  -> 103.75.25.75:80              Route   1      0          0   

The stickyness works fine on the local server, however when it syncs 
over to the backup, the timeout is wrong.

On master:
TCP 29:53  NONE        103.90.0.17:0      103.200.100.1:80   103.75.25.76:80

On slave:
TCP 02:57  NONE        103.90.0.17:0      103.200.100.1:80   103.75.25.76:80

Obviously there are instances when the backup connections timeout but 
they are in place on the master, so in the event the master fails, the 
slave doesn't have the connections in it's table.

Is there a workaround for this? Can I extend the timeout of synched 
connections via sysctl or something?
