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.

I installed libblockdev-nvdimm manually in my server but still issue persists and now it's something different.

Any idea?

This is another symptom of blivet not being good at handling missing dependencies. This was always an issue and we are working on fixing this but it's still work in progress and definitely not ready for 8.2.
We had a fix for the missing NVDIMM plugin ready because this was a newly added feature, but currently blivet won't work correctly without following libblockdev plugins: swap, crypto, loop, mdraid, mpath, dm.
I again suggest installing "libblockdev-plugins-all" as a workaround for this problem.
Comment 13 David Lehman 2020-03-11 23:24:33 UTC 
The RHEL installation media seems to pick up the libblockdev plugin packages (all of them) because anaconda requires libblockdev-plugins-all. How is it that your installation media does not have all of anaconda's dependencies? I must be missing something.
Comment 14 David Lehman 2020-03-11 23:27:15 UTC 
Ah, I think the answer to my question is that you are not using anaconda. If that is correct, probably the best solution is for you to add 'Requires: libblockdev-plugins-all' to the same spec file that has 'Requires: python3-blivet'. Is that possible?
Comment 15 Gobinda Das 2020-03-12 14:12:41 UTC 
Sandro, here is the patch https://gerrit.ovirt.org/#/c/107620/ to add libblockdev-plugins-all dependency in vdsm-gluster. Will this enough to pull libblockdev-plugins-all ?

It will be enough but sounds like a workaround for a blivet bug, will work for us but anyone else using blivet out of anaconda or vdsm scenario will hit this again.
Comment 19 Gobinda Das 2020-04-19 06:39:35 UTC 
Moving this back to NEW as I don't see a blivet build solving this.
Comment 24 RHEL Program Management 2021-09-06 07:27:07 UTC 
After evaluating this issue, there are no plans to address it further or fix it in an upcoming release.  Therefore, it is being closed.  If plans change such that this issue will be fixed in an upcoming release, then the bug can be reopened.
