Description Derek Anderson 2004-07-14 21:04:27 UTC

Description of problem:
Set up a three node cluster to the point of having cman quorum.  On
one node run 'cman_tool kill'.  The tool segfaults.  It also looks
from /proc/cluster/nodes that the cluster remains in.

[root@link-12 root]# cat /proc/cluster/nodes
Node  Votes Exp Sts  Name
   1    1    3   M   link-12.lab.msp.redhat.com
   2    1    3   M   link-10.lab.msp.redhat.com
   3    1    3   M   link-11.lab.msp.redhat.com
[root@link-12 root]# cman_tool kill
Segmentation fault
[root@link-12 root]# cat /proc/cluster/nodes
Node  Votes Exp Sts  Name
   1    1    3   M   link-12.lab.msp.redhat.com
   2    1    3   M   link-10.lab.msp.redhat.com
   3    1    3   M   link-11.lab.msp.redhat.com
[root@link-12 root]#

Version-Release number of selected component (if applicable):
cman_tool DEVEL.1089664733 (built Jul 12 2004 15:39:58)
Copyright (C) Red Hat, Inc.  2004  All rights reserved.

How reproducible:
100%

Steps to Reproduce:
1. insmod necessary modules on all
2. start ccsd on all
3. run 'cman_tool join' on all
4. run 'cman_tool kill' on one
  
Actual results:
Segmentation fault, node appears to stay in cluster

Expected results:
Not sure, what is the kill supposed to do?  Something other than the
Actual results.

Additional info:

Comment 1 Christine Caulfield 2004-07-19 10:16:08 UTC

kill needs the ID of the node to be killed. viz:

cman_tool kill -n3

Of course, it shouldn't crash without that, hence

Checking in main.c;
/cvs/cluster/cluster/cman/cman_tool/main.c,v  <--  main.c
new revision: 1.3; previous revision: 1.2
done


I feel a man page coming on....

Comment 2 Corey Marthaler 2004-08-26 19:39:09 UTC

Tested on three node cluster... no longer seg faults.

Comment 3 Kiersten (Kerri) Anderson 2004-11-16 19:07:17 UTC

Updating version to the right level in the defects.  Sorry for the storm.
