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the product is no longer active in Red Hat Bugzilla.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 of problem:
Currently the ocf:heartbeat:CTDB resource doesn't have a ctdb_max_open_files option. If this property is edited through /etc/ctdb/ctdb.conf it is eventually overwritten.
This could be resolved by either adding an option for ctdb_max_open_files, or by introducing an OPTIONAL, NON-DEFAULT way to make changes to CTDB_SYSCONFIG that won't be overwritten by generate_ctdb_sysconfig():
515 # Generate a new, minimal CTDB config file that's just enough
516 # to get CTDB running as configured by the RA parameters.
517 generate_ctdb_sysconfig() {
518 # Backup existing sysconfig if we're not already using an auto-generated one
519 grep -qa '# CTDB-RA: Auto-generated' $CTDB_SYSCONFIG || cp -p $CTDB_SYSCONFIG $CTDB_SYSCONFIG_BACKUP
520 if [ $? -ne 0 ]; then
