Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.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

Whiteboard:
Fixed In Version:	device-mapper-multipath-0.8.4-29.el8	Doc Type:	Bug Fix
Doc Text:	Cause: When multipath is configured with "find_multipaths smart" (which it is when booting into anaconda) and a new storage device appears, it starts a systemd timer to wait for another path to the device to appear. If this timer expires while the initramfs is cleaning up to pivot to the regular filesystem during boot, it will restart multipathd, which will stop systemd from cleaning up the initramfs. Consequence: systems can hang booting into anaconda during installation, if storage devices appear late enough in the initramfs portion of the bootup. Fix: The systemd timers now conflict with initramfs cleanup, so they will automatically get stopped when the system cleans up to pivot to the regular file system. They also no longer restart multipathd if it has stopped running Result: Systems no longer hang while booting into anaconda for installation.	Story Points:	---
