Having issues with adding a node to an existing cluster. Hope I am
just missing something simple.
RHEL 5.3 2 node cluster with quorum disk. Whenever I try to add a
third node with the luci admin interface the new node comes up with a
cluster.conf that looks like this
<?xml version="1.0"?>
<cluster config_version="1" name="xencluster">
<fence_daemon post_fail_delay="0" post_join_delay="3"/>
<clusternodes/>
<cman/>
<fencedevices/>
<rm/>
</cluster>
The 2 existing nodes get an updated cluster.conf, but the new node
doesn’t. Am I missing something? All I am doing is giving luci the
hostname and root password of the new node in the Add a node section.
luci that comes with 5.3/RHN has problem. Try luci with 5.2
I may be wrong. I just tried luci on my 5.2 system to add a node and it
failed. Anyway, it successful updates cluster.conf of existing nodes so
all I did after to add new node to the cluster is :
- scp /etc/cluster/* from existing node to new node
- install the following packages : gfs2-utils gfs-utils rgmanager
kmod-gfs2-xen kmod-gfs-xen lvm2-cluster. You may not need the *-xen-*
packages if you are not on a domU.
- start services cman, clvmd, gfs2 and rgmanager.
After that my new node joins the cluster just fine . Then luci sees my
new node, too.
I love luci, I hate lucy. I still not remember all the options of
cluster services so I still have to use it. For options I remember, I
just edit cluster.conf with vi and ccs_tool update.
