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 of problem:
The use_devicesfile was initially introduced in RHEL-9.0 via BZ#2012830 as a means to manage LVM devices and replace the traditional filter method. However, the old filter regex default to "accept all" devices. Only a blacklist was needed.
The introduction of use_devicesfile is enabled by default per BZ#2129176. This value results in non-bootable systems after upgrade and requires manual whitelisting of devices.
Version-Release number of selected component (if applicable):
9.0, 9.1, 9.2
How reproducible:
Very
Steps to Reproduce:
1. Install 9.1 (single disk, multiple disk, does not matter)
2. Upgrade to 9.2
3. System drops to maintenance mode
4. The system devices file does not contain all PV's.
Actual results:
System fails to boot and drops to maintenance mode. Requires manual intervention to either set `use_devicesfile = 0` or to manually add devices.
Expected results:
All devices get added to system devices, or set use_devicesfile to default to off.
Additional info:
This has affected multiple customers now, creating high visibility Sev 1 cases for support due to non bootable systems.

The other bug was actually a change in handling trailing spaces in t10 wwids. In 9.0/9.1 trailing spaces where replaced by _ and in 9.2 they are ignored. If system.devices on 9.0 or 9.1 contains an IDNAME starting with "t10" and ending with "_" then it's likely to run into bug 2208039 on upgrade.
