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).

Fixed In Version:	rhel-system-roles-1.11.0-1.el9	Doc Type:	Bug Fix
Doc Text:	.The Kdump RHEL System Role is be able to reboot, or indicate that a reboot is required Previously, the Kdump RHEL System Role ignored managed nodes without any reserved memory for crash kernel. Consequently, the role finished with the "Success" status, even if it did not configure the system properly. With this update of RHEL 9, the problem has been fixed. In cases when managed nodes do not have any memory reserved for the crash kernel, the Kdump RHEL System Role fails and suggests that users set the `kdump_reboot_ok` variable to `true` to properly configure the `kdump` service on managed nodes.

@spetrosi can you please provide the Doc Text for this issue?

Comment 3 Rich Megginson 2021-12-07 14:43:15 UTC

Systems that have the kdump service disabled might not have memory reserved and loaded for crashkernel. Such system require enabling kdump and rebooting, hence the kdump_reboot_ok variable must be added to the kdump role

How reproducible:


Steps to Reproduce:
Run the role on the system with disabled kdump. I.e. the `/sys/kernel/kexec_crash_size` file on the system contains `0`.


Actual results:
The role either fails or passes without errors 

Expected results:
The role passes and sets the `kdump_reboot_required` fact to indicate that reboot is required. Or passes with reboot if `kdump_reboot_ok: true` is set.
