Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

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.

Doc Text:	.LVM `system.devices` file feature now available in RHEL 8 RHEL 8.5 introduces the LVM `system.devices` file feature. By creating a list of devices in the `/etc/lvm/devices/system.devices` file, you can select specific devices for LVM to recognize and use, and prevent LVM from using unwanted devices. To enable the `system.devices` file feature, set `use_devicesfile=1` in the `lvm.conf` configuration file and add devices to the `system.devices` file. LVM ignores any devices filter settings while the `system.devices` file feature is enabled. To prevent warning messages, remove your filter settings from the `lvm.conf` file. For more information, see the `lvmdevices(8)` man page.	Story Points:	---

Regression tests have been run with the devices file enabled and cursory checks of the new 'lvmdevices' and 'vgimportdevices' commands have passed.
