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?
ah, sorry.. I see, it's a real error message... Seems to be a race.
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,

> (In reply to comment #4) > > customer wants to know the progress of this bug 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.
