So, I've created a new ZenLB CE Cluster on a pair of systems. The
setup involved a pair of NICs on each system. I'll try and explain
below.
-----
netlb01 - eth0 - 10.26.250.63
- eth1 - 10.26.251.60
netlb02 - eth0 - 10.26.250.64
- eth1 - 10.26.251.61
cluster interface: eth1:1 - 10.26.251.59
-----
I generally like to create cluster interfaces on a dedicated network
to isolate the traffic and also provide redundancy for clustering tech
that allow it (dual paths).
In any case, this is a setup I've used with ZenLB before in the past
generally without issue, but this time I have a problem where eth0 on
netlb02 (the secondary node) does not come up now (started the moment
the cluster was configured which appears to have been successful).
I've looked a the configs for obvious issues like IP conflicts and
what-not and so far, I can't find anything.
I'm wondering if this is something anyone else has encountered. I've
looked at the configs in /usr/local/zenloadbalancer/config and thus
far I can't find anything obvious.
For example (file contents on netlb02):
===== if_eth0_conf ======
eth0::10.26.250.64:255.255.255.0:up::
===== if_eth0:ntp_conf ======
eth0:ntp:10.26.250.24:255.255.255.0:up::
===== if_eth1:1_conf ======
eth1:1:10.26.251.59:255.255.255.0:up::
===== if_eth1_conf ======
eth1::10.26.251.61:255.255.255.0:up::
---------------------
The same on netlb01:
===== if_eth0_conf ======
eth0::10.26.250.63:255.255.255.0:up::
===== if_eth0:ntp_conf ======
eth0:ntp:10.26.250.24:255.255.255.0:up::
===== if_eth1:1_conf ======
eth1:1:10.26.251.59:255.255.255.0:up::
===== if_eth1_conf ======
eth1::10.26.251.60:255.255.255.0:up::
