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.

pvscan with lvm 2.03.14-3
Description of problem:
After upgrading from 8.5 to 8.6 the non-root VG are not detected anymore.
Downgrading lvm2 to lvm2-2.03.12-11.el8_5.x86_64 (with dependencies: device-mapper-1.02.177-11) fixes the issue.
Version-Release number of selected component (if applicable):
lvm2-2.03.14-3 and device-mapper-1.02.181-3
How reproducible:
Always
Steps to Reproduce:
1. Upgrade lvm2 to latest.
2.
3.
Actual results:
Only root PV is detected
Expected results:
All 3 PV should be detected.
Additional info:
In 8.6 lvm began using /etc/multipath/wwids to help identify multipath components, which should be ignored. The attached pvscan shows the wwids for sdb1 and sdc1 are listed in /etc/multipath/wwids, so lvm ignores them:
pvscan[15665] device/dev-mpath.c:461 dev_is_mpath_component /dev/sdb1 multipath wwid 600508b1001c4f1808d6eace1ae87229
pvscan[15665] device/dev-mpath.c:461 dev_is_mpath_component /dev/sdc1 multipath wwid 600508b1001cfd059e1b819a16d14d53
If you're not using multipath on these devices, you should remove their wwids from /etc/multipath/wwids. If you're trying to use the multipath blacklist with these wwids, then this is a known problem (bug 2076262) and will be fixed in the next release. Another option is to disable lvm's use of /etc/multipath/wwids by setting lvm.conf multipath_wwids_file="".
