Description Corey Marthaler 2004-09-09 23:08:12 UTC

Description of problem:
I changed all the nodes in my cluster.conf file to FQDN to get around
bz 126971 and cman_tool will not let me join the cluster. Even with
the -n FQDN.

[root@morph-01 root]# cman_tool join -n morph-01.lab.msp.redhat.com
ccs values will override some command line values
cman_tool: cannot find local node name "morph-01" in ccs


[root@morph-01 root]# cat /etc/cluster/cluster.conf
<?xml version="1.0"?>
<cluster name="morph-cluster" config_version="1">

<cman>
</cman>

Comment 1 Christine Caulfield 2004-09-10 06:57:01 UTC

Yep, that's what it' supposed to do.

cman_tool strips off the domain name.

Comment 2 Corey Marthaler 2004-09-10 16:48:30 UTC

It sounds like the only thing allowed in the cluster.conf file is 
the short name of the machine, and in that case gulm isn't happy. 
 
I argue that you should be able to have short names, FQDNs, and 
IPaddrs in the cluster.conf file and it should all just work.

Comment 3 Christine Caulfield 2004-09-13 09:48:05 UTC

OK, this is not very nice but it is a little more flexible. cman_tool
will now allow FQDNs in cluster.conf and will truncate them as it
passes them into the kernel.

If you do use them in cluster.conf then uname MUST also return the
FQDN or you will have to do the -n override thing (ugh!)

I will not add support for IP addresses to cman_tool unless Kevin
leans on me very heavily.
