Red hat cluster

[Eli_pok]

Hi,

I'm having a very strange problem with red hat cluster.
After testing it in the lab, I tried to install a new cluster and received the following error :

cman not started: Cannot start, cluster name is too long or other CCS error /usr/sbin/cman_tool: aisexec daemon didn't start

I've checked the internet for that error, but nothing. I decided to to take the example from cluster.conf man, which looks like that :












And still I get the same error.
I can find my servers both from DNS (FQDN and short name) and they also appear in /etc/hosts.

Any ideas ?

What version of RHEL?

Did you use the Console to set up your cluster or manual editing of files?

I suggest using Luci/Rici combo to manage your cluster via a nice web frontend.

For my real cluster.conf I've used system-config-cluster.
I've found it more comfortable from the web gui.
But I've also tried creating the file in simple vi ediditng, and through luci.. the problem stays the same.
I suspect it has somthing to do with AIS and not the cluster.conf file (you can see the current configuration, it's simple as it can be and it's also not working)

The version is 5.5 , forgot to mention

Then I suggest starting over again, wipe your cluster.conf clean and follow your recipe for setting up your cluster -- CLI/TUI wizard or Web.. someting is obviously missing.


Do you use just one LAN or 2 or more?

It looks like it had trouble with the second nic as you said.

I cannt undestand why, and even more why the error was so unclear.
