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.

Comment 1 Chris Feist 2011-08-16 18:19:49 UTC 
Easy to replicate:

[root@ask-03 ~]# echo "<test>" > /tmp/blah
[root@ask-03 ~]# ccs -f /tmp/blah --getconf
Traceback (most recent call last):
  File "/usr/sbin/ccs", line 2143, 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 746, in get_cluster_conf_xml
    dom = minidom.parseString(xml)
  File "/usr/lib64/python2.6/site-packages/_xmlplus/dom/minidom.py", line 1925, in parseString
    return expatbuilder.parseString(string)
  File "/usr/lib64/python2.6/site-packages/_xmlplus/dom/expatbuilder.py", line 942, in parseString
    return builder.parseString(string)
  File "/usr/lib64/python2.6/site-packages/_xmlplus/dom/expatbuilder.py", line 223, in parseString
    parser.Parse(string, True)
xml.parsers.expat.ExpatError: no element found: line 2, column 0


It should just print out an error saying something to the effect of "Bad cluster file specified."

Comment 7 Chris Feist 2012-02-28 00:12:27 UTC 
Using ricci-0.16.2-48.el6:

[root@ask-04 tmp]# echo "<test>" > /tmp/blah
[root@ask-04 tmp]# ccs -f /tmp/blah --getconf
Cluster configuration file specified is not in a valid xml format.
