Hi,
I have attached a patch(will send it out separately when i get my hands on the
latest review tool). However, please find my comments
1) w.r.t the log string and its relevance to /etc/opensaf/node_name:
The /etc/opensaf/node_name is an user exposed configuration file.
The node_name file contains the RDN value of the CLM node name.
(a) When opensaf cluster configuration is pre-provisioned using the OpenSAF IMM
tools:
the /etc/opensaf/node_name should contain one of the values specified
in nodes.cfg while generating the imm.xml.
(b) When opensaf cluster nodes are dynamically added at runtime:
the /etc/opensaf/node_name should contain the rdn value.
So, to the end user, the log messages should convey the relationship with the
node_name file in some grammar. I have changed the log to notice though and
reframed with your inputs also in the attached patch.
2) w.r.t the use case
I think it is primarily a case of non-existent configuration and also a case of
invalid configuration.
In the cluster expansion case, i think the expansion logic should first update
the cluster configuration, because otherwise the node startup will still be
seen as afailure attempt for the "unconfigured" node.
Note: Since, there is a way around the situation, i have changed the prioroity
to major. I will send a formal review request later, but please use the
attached patch(modified your patch with my impressions).

** [tickets:#816] CLM causes cluster restart when unknown node tries to join**
**Status:** accepted
**Milestone:** 4.4.1
**Created:** Fri Mar 21, 2014 01:15 PM UTC by Hans Feldt
**Last Updated:** Fri Mar 21, 2014 01:15 PM UTC

When an unconfigured node tries to join an existing 4.4 CLM cluster the
osafclmd process segfaults, after failover the new active osafclmd segfaults
and we get a cluster restart.
Mar 21 14:06:12 SC-1 local0.err osafclmd[418]: ER CLM NodeName: 'PL-6' doesn't

The log entry is also wrong. It has the wrong level ER. It does not have to be
an error, this would happen during scale out - adding a new node. Should be
notice. The text itself is also not correct since it is normally not related to
imm.xml or contents of node_name.
I suggest the following log instead; "NO '<RDN value>' is not a configured
cluster node"
This is a regression, it works with 4.3
Patch attached with proposed solution.
