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.

kdump setting picture
Description of problem:
Kdump can be located in Local/nfs/ssh with cockpit WebUI, local file-system is the default. If a user wants to use NFS/SSH for kdump, the location should be changed to "Use the setting in /etc/kdump.conf" with cockpit UI. But now apply changing failed, location still points to "locally in /var/crash", and vmcore files are still created in /etc/crash of localhost.
Version-Release number of selected component (if applicable):
redhat-virtualization-host-4.2-20180115.0
cockpit-ws-157-1.el7.x86_64
cockpit-dashboard-157-1.el7.x86_64
cockpit-bridge-157-1.el7.x86_64
cockpit-157-1.el7.x86_64
cockpit-storaged-157-1.el7.noarch
cockpit-system-157-1.el7.noarch
cockpit-ovirt-dashboard-0.11.4-0.1.el7ev.noarch
kernel-3.10.0-693.11.6.el7.x86_64
How reproducible:
100%
Steps to Reproduce:
1. Clean install redhat-virtualization-host-4.2-20180115.0 with ks
2. Login to cockpit with root account
3. Go to Kernel Dump, open Crash dump location window
4. Apply the location to "Use the setting in /etc/kdump.conf" after setting nfs/ssh kdump in /etc/kdump.conf file
5. Check the setting in cockpit UI
6. Click "Test Configuration", then "Crash system"
Actual results:
After step 5, changing kdump location to"Use the setting in /etc/kdump.conf" failed, location still points to "locally in /var/crash".
After step 6, vmcore files are created in /etc/crash of localhost.
Expected results:
After step 5, the location should point to nfs/ssh address.
After step 6, vmcore files should be created in remote nfs/ssh server.
Additional info:
What does work is to edit /etc/kdump.conf, disable "path" and enable "nfs", then the Cockpit display immediately changes to "Remote over NFS". Then it's also possible to change the NFS location in the Cockpit UI.
But this already fails again when enabling "ssh" or "ext4" in kdump.conf, then the UI immediately switches back to "locally in /var/crash".
Also, changing the path in kdump.conf to "path /var/crash2" or something else isn't properly reflected in the UI. This only works in the Cockpit → config file direction.
