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 Type: Bug Fix
Doc Text:
Currently when multipath runs in the initramfs with user_friendly_names set, if it doesn't find existing mappings in /etc/multipath/bindings, it creates new ones, just like it does once the node is in normal operation. Unfortunately, these can conflict with the user_friendly_names set in the normal filesystem's /etc/multipath/bindings. dracut now starts the multipathd daemon with the new -B option, which causes multipath to treat the bindings file as read-only.

Patch to add the -B option

Currently when multipath runs in the initramfs with user_friendly_names set, if it doesn't find existing mappings in /etc/multipath/bindings, it creates new ones, just like it does once the node is in normal operation.  Unfortunately, these can conflict with the user_friendly_names set in the normal filesystem's /etc/multipath/bindings. The new -B option caused multipath to treat the bindings file as read-only.  This option should be added to the dracut multipath scripts.

Comment 4 Jan Stodola 2011-04-29 07:52:56 UTC 
Tested on build RHEL6.1-20110427.0 with dracut-004-53.el6.noarch on s390x architecture. Root filesystem was placed on a multipath zFCP LUN. The following log comes from /init.log from initramfs:
...
+ [ -e /pre-trigger/02multipathd.sh ]
+ . /pre-trigger/02multipathd.sh
+ [ -e /etc/multipath.conf ]
+ modprobe dm-multipath
+ multipathd -B
+ [ -e /pre-trigger/10plymouth-pretrigger.sh ]
+ . /pre-trigger/10plymouth-pretrigger.sh
+ getarg rd_NO_PLYMOUTH
...

multipathd was run with the -B option.

Moving to VERIFIED.
