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:
When upgrading kmod-kvdo rpm with running vod (kvdo module in use), the result is have both version installed. This is because the old version is not removed as the module is still loaded, but the new version gets installed.

This confuses yum as it thinks the old version is the one installed, so for example trying to update it again leads to conflict errors in transaction check:
# yum install http://*****/brewroot/packages/kmod-kvdo/6.1.0.168/16.el7_5/x86_64/kmod-kvdo-6.1.0.168-16.el7_5.x86_64.rpm -y

Your transaction was saved, rerun it with:
 yum load-transaction /tmp/yum_save_tx.2018-05-03.10-48.grVJHd.yumtx

Version-Release number of selected component (if applicable):
kmod-kvdo-6.1.0.153-15.el7.x86_64 and kmod-kvdo-6.1.0.168-16.el7_5.x86_64

Also the loaded module is 6.1.0.153 and even sequence: removing all running VDOs, rmmod kvdo, depmod -a, modprobe kvdo and modinfo kvdo returns the old version (6.1.0.153). To be able to load the new version with 'modprobe kvdo' user has to specifically remove the old version of the package.

How reproducible:
100%

Steps to Reproduce:
1. yum install kmod-kvdo-OLD
2. vdo create --name vdo --device device
3. yum install kmod-kvdo-NEW

Actual results:
both kmod-kvdo-OLD and kmod-kvdo-NEW are installed
yum info reports both versions
yum install kmod-kvdo-OLD reports the old as newest
yum install kmod-kvdo-NEW tries to update it again
old version is still loading into kernel as long as the old package is installed

Expected results:
probably fail to install the update when the updated package is not removed as the new module cannot be easily loaded anyway as long as the old package is there.

This is due to a bug in yum and I've been unable to find a workaround.

I think the fix to this is described in BZ 1553420, please have look.

What is the workaround?
Thanks
Comment 8 Andy Walsh 2024-01-29 17:09:11 UTC 
hi @dennis.charipar, We don't have any way to fix this, as noted in Comment#2.  Though the issue in Comment#3 shows that we added some output to indicate when there are reasons to prevent the removal of one version of kmod-kvdo for the next.  Make sure that if you have a VDO volume on the system that you've unmounted and stopped any of the volumes before proceeding.  If that doesn't work, then I don't believe we have a known fix for what you're seeing.

All that being said, a workaround to this particular issue can be to just uninstall kmod-kvdo prior to performing the upgrade and then re-install it when you're finished.
