If your device is mounted, you won't be able to flush it, flush == destroy.
OK. so it's not just you, I can recreate this. Coincidentally, I also have an HP RAID controller and see the same warning message. This device *is blacklisted* but apparently it's still getting probed. Shouldn't be causing any problems, though blacklisted should mean what it says. ** Changed in: multipath-tools (Ubuntu) Status: Incomplete => Confirmed -- 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/1013724 Title: Setting "prio const" in multipath.conf has no effect To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/multipath-tools/+bug/1013724/+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
