This behaviour actually not only breaks the autodetection of (complete) hot plugged md arrays from another systems, but breaks every array newly created on ubuntu systems (as ubuntu uses the hotplug scheme) .
For instructions on updating the initramfs refer to: http://ubuntuforums.org/showthread.php?p=8407182 ** Summary changed: - mdadm.conf created with explicit ARRAY statements, and HOMEHOST !=any prevents hotplug autodetection + mdadm.conf with explicit ARRAY statements, and HOMEHOST !=any prevents hotplug setup -- raid setup fails due to mdadm.conf with explicit ARRAY statements and HOMEHOST !=any https://bugs.launchpad.net/bugs/252345 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
