We recently switched from ldirectord to keepalived. We noticed that,
after the switch, LVS behaves a bit differently with respect to “down”
services.
On ldirectord, a virtual service with 2 realservers displays “Masq 0”
when one of them is down.
TCP 192.168.5.100:3002 wlc persistent 50
-> 192.168.8.53:3002 Masq 1 0 0
-> 192.168.8.55:3002 Masq 0 0 4
On keepalived, it does not shown the down server at all…
TCP 192.168.5.100:3002 wlc persistent 50
-> 192.168.8.53:3002 Masq 1 0 0
Why is that? It makes it impossible to see when services are down.
Hi Eric,
I think you're showing the output of ``ipvsadm -Ln'' here, right?
If so, what OS are you using? I observed similar behaviour when moving
from CentOS 6 to CentOS 7 (i.e. Kernel 2.6.x to Kernel 3.10.x), so there
may have changed default values of displaying stuff or APIs.
Timo
