[linux-lvm] clvmd cman and co by a noob@clustering

[jmfaidy]

Hello everybody,
I'm trying to configure a cluster architecture, but i encounter some issues.
I'm doing this on a dom0 2.6.18-1.2798.fc6xen.
My goal is to use xen-heartbeat-clvmd-iscsi-drbd.
First, i can't start clvmd, thr message is : "clvmd could not connect  
to cluster manager"
So, if i don't mistake, the cluster manager should be cman ? I hope i'm true.
So I try to start cman, here is one of the message i have :

"Starting cluster:
    Loading modules... done
    Mounting configfs... done
    Starting ccsd... done
    Starting cman... failed
cman not started: Local host name resolves to 127.0.0.1; fix  
/etc/hosts before starting cluster. /usr/sbin/cm
an_tool: aisexec daemon didn't start
                                                            [�CHOU�]"
but sometimes i have some other message, like "node have no node id  
while i have the <nodeid="1"> in cluster.conf xml file.

I'm sur i've miss some thing to do to configure everything.
It would be great if someone have a hint for me...
TY
have a nice day.

JiM

you would be better off sending this to linux-cluster@redhat.com instead 
of linux-lvm.

You might want to check out the link below too. It should address one of 
the problems. ie, is sounds like your hostname resolves to the loopback 
address.

http://www.redhat.com/docs/manuals/csgfs/browse/rh-cs-en/s1-hardware-linux.html#S2-HARDWARE-ETCHOSTS

And this one may be useful too.

Right, i forgot this list, as my problem was about lvm2/clvm, but i'll  
try, tx.
Tx for the links, even if i knew them.
I found a part of my problem, in my default /etc/hosts, there was a  
line which i don't know the use (i'm sur its about ipv6) : "::1  
localhost" i finally tryed to remove it, and it remove my error, well,  
a new one appears ofc... ;)
Tx for he reply.
