Description Chris Feist 2011-07-13 18:42:19 UTC

Description of problem:
When a node has ricci installed and running, but not clustermon, many ccs functions cause a backtrace.

Version-Release number of selected component (if applicable):
ricci-0.16.2-35.el6.x86_64
ccs-0.16.2-35.el6.x86_64

How reproducible:
All the time

Steps to Reproduce:
1.  Have a node with ricci installed, but not cman
2.  Run 'ccs -h localhost --getconf' on the node.

  
Actual results:
Backtrace.

Expected results:
Warning about clustermon not installed, or at least ricci not ready.

Comment 6 Chris Feist 2012-02-03 23:04:14 UTC

To replicate:


[root@amoco-01 ~]# rpm -e --nodeps modcluster
[root@amoco-01 ~]# ccs -h localhost --getconf
Traceback (most recent call last):
  File "/usr/sbin/ccs", line 2144, in <module>
    main(sys.argv[1:])
  File "/usr/sbin/ccs", line 240, in main
    if (getconf): get_cluster_conf()
  File "/usr/sbin/ccs", line 588, in get_cluster_conf
    xml = get_cluster_conf_xml()
  File "/usr/sbin/ccs", line 744, in get_cluster_conf_xml
    xml = send_ricci_command("cluster", "get_cluster.conf")
  File "/usr/sbin/ccs", line 2061, in send_ricci_command
    xml = dom.getElementsByTagName('function_response')[0].toxml()
IndexError: list index out of range

With new package:
[cfeist@gold ccs]$ ./ccs -i -h amoco-01 --getconf
Error: Unable to retrieve information from ricci (is modcluster installed?)


[root@amoco-01 ~]# yum install modcluster
...

[cfeist@gold ccs]$ ./ccs -i -h amoco-01 --getconf

Using ricci-0.16.2-48.el6:


[root@ask-04 tmp]# rpm -e --nodeps modcluster
[root@ask-04 tmp]# ccs -h localhost --getconf
Error: Unable to retrieve information from ricci (is modcluster installed?)
