I think blacklist device maching is expanded as a regex and not as a glob, thus the * will not provide a match. Can you try the following change.
Replace: device { vendor "DELL*" product "PERC*" } With: device { vendor DELL.* product PERC.* } Also if you could paste the output from $ sudo udisks --dump It would help debug this issue, I am not on the Ubuntu team but I am trying to track down an issue that may be related to this. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to multipath-tools in Ubuntu. https://bugs.launchpad.net/bugs/927540 Title: multipath ignores blacklist in multipath.conf To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/multipath-tools/+bug/927540/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
