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.

Comment 1 Dimitri Savineau 2022-06-23 14:33:56 UTC 
This is likely an issue in rhel-system-roles rather than ansible-core itself.

The issue is probably coming from a bad input generated for the "Check the type of each PV" task.

It will be easier for debug purpose to get the full ansible log with verbosity.

For what it's worth, I'm not able to reproduce the issue on my side.

Hi，Dimitri

Thanks for point out that，
I reproduce this with
blivet-data-3.4.0-15.el9.noarch
python3-blivet-3.4.0-15.el9.noarch
and upstream linux-system-roles case，compared with downstream, case has some modification

Thanks
Changhui
