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 Kairui Song 2020-11-19 09:54:19 UTC
Description of problem:
Currently dracut's 95fcoe module will always be installed, when there are any FCoE device on the machine.
But when building hostonly initramfs, only specified devices are used in initramfs, so installing the FCoE module is unnecessary.

Dracut should drop FCoE in hostonly mode when there is no hostonly FCoE device module, this is especially helpful for kdump.

How reproducible:
100%

Steps to Reproduce:
It can be reproduced with kdump:
1. Setup FCoE device.
2. Set the kdump target to a network device, and then restart kdump. 
2. Kdump will rebuild the initramfs, and fcoe dracut module is installed.

Actual results:
fcoe dracut module is installed in kdump initramfs

Expected results:
fcoe dracut module should not be installed in kdump initramfs
