Every time I touch something, pieces fall off! It's a good thing this stuff isn't in production yet (for me I mean).
So I had an LVS, configured with Piranha, directing http test transactions across two servers. I used Piranha to add another realserver. It appeared in the lvs.cf file, but didn't appear in the ipvsadm output. So I stopped and restarted Pulse. And now *none* of the servers appear in the ipvsadm output. Pulse says it started clean, and nothing in the syslog. The gratuitous arp gets made, and the correct IPs are assigned to the correct interfaces.
[ddb@prcapp02 ~]$ sudo ipvsadm IP Virtual Server version 1.2.1 (size=4096) Prot LocalAddress:Port Scheduler Flags -> RemoteAddress:Port Forward Weight ActiveConn InActConn TCP prcvmod01.pinerivercapital.l wlc
That's the write service name (the ".l" at the end is ".local" truncated). WLC is the right scheduling mode. But no remote addresses are listed.
In lvs.cf, there are multiple servers present: server vl31 { address = 172.17.3.1 active = 1 weight = 2 } server vw32 { address = 172.17.3.2 active = 1 weight = 2 } server vl41 { address = 172.17.4.1 active = 1 weight = 4 }
