The -p is to disable dmraid's internal handling of partitions in favor of letting kpartx take care of it. This was done because kpartx also supports GPT, but dmraid does not.
Can you try updating your initramfs and see if that helps? sudo update-initramfs -u Also please make sure you are running the -ubuntu7 version of dmraid. -- 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/941874 Title: (fakeraid) root device not activated during boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dmraid/+bug/941874/+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
