740552 – <altname ../> element validation is position dependent

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 Jaroslav Kortus 2011-09-22 12:43:26 UTC

Description of problem:
<altname ../> element validation is position dependent
If it's the first element of <clusternode> then it works, if it's the last element there then it does not work.

Version-Release number of selected component (if applicable):
cman-3.0.12.1-21.el6.x86_64


How reproducible:
100%

Steps to Reproduce:
1. add <altname> as a first tag
2. ccs_config_validate
3. move the <altname> tag so that it's the last element of <clusternode>
4. ccs_config_validate
  
Actual results:
step 4 fails:
tempfile:15: element altname: Relax-NG validity error : Element clusternode has extra content: altname
tempfile:6: element clusternode: Relax-NG validity error : Element clusternodes has extra content: clusternode


Expected results:
Configuration validates
