These machines were upgraded from F9 and then began having these mysterious changes occur with these /dev/dm-N entries. These devices bear no resemblence to any mdraid devices or LVM devices and our scripts completely croak with these devices. Why are perfectly good devices being renamed to absolutely useless names? All I want to know is how to stop whatever it is that is causing this.2009/4/22 Gerry Reno <greno verizon net>:Gerry Reno wrote:We just upgraded a number of machines to F10 and after a few weeks I've noticed something wrong with lvm.

I don't find it referencedin any of the lvm tool outputs. Whatever caused this change to happenplease revert this back to just listing lv's in normal lvm parlance please. These mysterious changes are breaking things and are a complete nuisance. How do we go about undoing these changes and how do we prevent this fromhappening again? Regards, Gerryhappen. How can we prevent this from happening?Not sure what would cause that. Perhaps related to this bug: https://bugzilla.redhat.com/show_bug.cgi?id=475773 Can you look back through /var/log/yum.log to work out which set of package updates may have triggered the problem - that might provide a clue.Regards, Gerry
