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 mjin 2012-07-09 07:12:54 UTC 
Description of problem:

With multipath, all the different paths for a device trigger the same by-uuid rule.  It tries to make the uuid symlink for every path, but only the first one succeeds.  The others fail with File exists.

did you turn on debug or did you strace?
Comment 3 Harald Hoyer 2012-07-09 14:24:11 UTC 
ah, sorry.. I see, it's a real error message... Seems to be a race.
Comment 4 mjin 2012-07-12 01:29:39 UTC 
customer wants to know the progress of this bug, so i am changing view right from Red Hat Employee (internal) -> ALL, 

Please correct me if something wrong with such action,

no problem

We have a solution, which basically circumvents the error message, but not the outcome.

As Harald said, the "fix" is to suppress the message of racing events
fighting about the same symlink name. It's nothing udev could work
around or solve.

There will be no change in behaviour, besides that it is not logged any more.
