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.

console log

Description of problem:
Kdump to LVM LV on RHEV-H does not succeed -- times out waiting to mount in the kdump initramfs

Version-Release number of selected component (if applicable):
kexec-tools-2.0.7-8.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Install RHEV-H 7
2. Local kdump is already configured
3. Rebuild initramfs with dmsquash-live included
4. Trigger a dump

Actual results:
Timeout in the kdump initramfs waiting for the LV to be available.

Dracut debug shell shows that no LVM groups are active. Manually activating them creates no devices in /dev/mapper or /dev/HostVG

Expected results:
kdump works


Additional info:
Output from the serial console of a vm booted with "rd.debug rdudevdebug verbose debug" is attached, where the problem can hopefully be located.

Please needinfo myself or Fabian if you need help installing or configuring RHEV-H

Please test kexec-tools-2.0.7-15.el7.

According to https://bugzilla.redhat.com/show_bug.cgi?id=1095140#c33
the issue is verified.
