I was never able to get marginal_pathgroups to switch values on a multipathd reload. That should be the case, because you are not allowed to switch the marginal_pathgroups setting either to or from "fpin" on a reconfigure. It needs to be there from when multipathd starts up to work correctly. If you look in the log messages you posted, you can see lines like: Sep 26 07:22:43 storageqe-05 multipathd[32057]: reconfigure (operator) Sep 26 07:22:43 storageqe-05 multipathd[33045]: ok Sep 26 07:22:43 storageqe-05 multipathd[32057]: multipathd must be restarted to turn off fpin marginal paths The same thing happens if you start with marginal_pathgroups set to something other than fpin, and try to change it to fpin on a reload. You say that it did change sometimes, but is it possible that occasionally you ran # service multipathd restart instead of # service mulitpathd reload In this case it would be able to change. If you can still reproduce this, sending me a script to do it would be helpful, since I couldn't make it switch randomly when I tried. Issue migration from Bugzilla to Jira is in process at this time. This will be the last message in Jira copied from the Bugzilla bug. This BZ has been automatically migrated to the issues.redhat.com Red Hat Issue Tracker. All future work related to this report will be managed there. Due to differences in account names between systems, some fields were not replicated. Be sure to add yourself to Jira issue's "Watchers" field to continue receiving updates and add others to the "Need Info From" field to continue requesting information. To find the migrated issue, look in the "Links" section for a direct link to the new issue location. The issue key will have an icon of 2 footprints next to it, and begin with "RHEL-" followed by an integer.
