Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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
