Re: [Linux-cluster] cman startup issue

I'm having a weird problem. I am using a shared GFS root file system,
and the same initrd image on all the machines. The cluster has 3
machines on it at the moment, and 1 refuses to join the cluster,
regardless of which order I bring them up in.

When cman service is being started, it fails when starting cman:

cman not started: Can't find local node name in cluster.conf
/usr/local/sbin/cman_tool: aisexec daemon didn't start

If I try to run aisexec, I get:
aisexec: totemsrp.c:2867: memb_ring_id_store: Assertion `0' failed.

Where should I be looking for causes of this? I double checked my
cluster.conf and the MAC addresses, IP addresses and interface names are
correct in each node's config.

Check that the new node can write into /tmp - where it is trying to
store the
current ring-id.  It could be SElinux or perhaps the permissions on
the file it
is trying to create.

That fixed the aisexec problem, but the "Can't find local node name in
cluster.conf" problem remains, and cman still won't start. :-(

Well, it won't start if it can' find the local node name in cluster.conf ...
Have you double-checked that the name(s) in cluster.conf match those on the
ethernet interfaces ?

You mean as in:
<eth name="eth1" mac="my:ma:ca:dd:re:ss" ip="" mask=""/>

If so, then yes, I checked it about 10 times. That was the first thing I thought was wrong. :-(
