Re: F7: Clustermanager (cman) does not start

[Thomas Stinner <thomas.stinner@xxxxxxxxxxxx>]

Hi,

thanks for the fast response.

i am using the rpms from the original Fedora repository:

cman.x86_64                              2.0.60-3.fc7           installed
openais.x86_64                           0.80.1-6               installed
gfs2-utils.x86_64                        0.1.25-1.fc7           installed


When i manually try to start the cluster i get the same error when issuing "cman_tool join".

My cluster.conf looks like this:

<?xml version="1.0" ?>
<cluster alias="xencluster" config_version="3" name="alpha_cluster">
        <fence_daemon post_fail_delay="0" post_join_delay="3"/>

Hi

Stop  every services of gfs2

Check that the xml file is correct under the /etc/cluster/cluster.config
Check that every node are mapped into the file /etc/hosts or resolved by dns system.

Reboot the system and without the gfs services and openais services launch this in every nodes:

modprobe gfs2
modprobe lock_dlm
modprobe lock_nolock
modprobe dlm
mount -t configfs none /sys/kernel/config
ccsd
cman_tool join
groupd
fenced
fence_tool join
dlm_controld
gfs_controld

after this, check if the cluster is full functionally with :

cman_tool status
cman nodes

I hope that you install from the originally cvs, in every case look the usage.txt under doc directory from the original repository.

If you dont have this files look here:
