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 Corey Marthaler 2022-05-12 18:21:27 UTC 
Description of problem:
This test was attempting to force delete a single device that was still in-use and a part of a partial VG that was missing all its other PVs.


SCENARIO - duplicate_vg_uuids_with_devicesfile_enabled:  Test how LVM reacts to PVs having the same pv and vg uuids while devicesfile is enabled (bug 2040456) 
adding entry to the devices file for /dev/sdd1
creating PV on hayes-03 using device /dev/sdd1
pvcreate --yes -ff   /dev/sdd1
  Can't open /dev/sdd1 exclusively.  Mounted filesystem?

Comment 2 Tony Asleson 2022-05-17 15:48:58 UTC 
Please let me know steps to reproduce or location of unit test itself.  I followed the steps in bug 2040456 but the dameon did not raise an exception.
Comment 3 Corey Marthaler 2022-05-17 17:59:14 UTC 
Correct, the steps in comment #0 are just a single pvcreate that would not be enough to reproduce this. There were labels left on these devices from prior test runs that I need to dig into and hopefully figure out a reproducer for. 

I filed this a both a place holder to do just that and to maybe see if exception rang a bell for you as to how it might be possible.
Comment 4 Corey Marthaler 2022-09-13 16:54:29 UTC 
Saw this again today with the latest 8.7 rpms. I'll post the full log as well.
