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 Matej Marušák 2019-04-10 04:23:57 UTC
Description of problem:
On RHEL 8-1 image (virt-install from nightly compose), kvdo is broken:

# modinfo vdo
modinfo: ERROR: Module vdo not found.

# find /lib/modules -name '*vdo*'
/lib/modules/4.18.0-72.el8.x86_64/extra/kmod-kvdo
/lib/modules/4.18.0-72.el8.x86_64/extra/kmod-kvdo/vdo
/lib/modules/4.18.0-72.el8.x86_64/extra/kmod-kvdo/vdo/kvdo.ko

# uname -r
4.18.0-80.10.el8.x86_64

The version of kernel does not match the version of module.

Version-Release number of selected component (if applicable):
kmod-kvdo-6.2.0.293-50.el8.x86_64
kernel-4.18.0-80.10.el8.x86_64

How reproducible:
Always

Steps to Reproduce:
1. modprobe kvdo

Actual results:
modprobe: FATAL: Module kvdo not found in directory /lib/modules/4.18.0-80.10.el8.x86_64

Expected results:
`modprobe kvdo` does not fail.


Additional info:
This is almost the same as https://bugzilla.redhat.com/show_bug.cgi?id=1637911 only with different version of kernel
