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 2022-01-12 20:15:07 UTC 
Description of problem:
I wrote a scenario to corrupt each of the attributes of a devicesfile entry and it didn't appear that the check or update options do anything with the corruption.

Comment 1 David Teigland 2022-01-12 23:07:03 UTC 
The purpose of lvmdevices check|update is only vaguely described in the man page, so the main thing to do is to precisely define what is actually checked and fixed.  It's primarily the unstable DEVNAME field, but there might be one or two other things.
Comment 2 David Teigland 2022-01-14 21:55:37 UTC 
in stable branch: https://sourceware.org/git/?p=lvm2.git;a=commit;h=bb477d63e336a10e5959962a9f26a028ea9e55eb

This improves the lvmdevices check output to have an error exit if the devices file needs an update.
Comment 6 Corey Marthaler 2022-07-15 20:06:13 UTC 
Marking verified in the latest rpms.
