I've had this problem since wily (15.10) - the workarounds in this ticket stopped working then. It's still the same in xenial (upgraded yesterday, so it's fresh).
Fwiw I can say it's still a problem at shutdown rather than startup: If I reboot to Windows it's detected as unclean and a resync is done, and if I shut down Windows with the raid clean it starts clean in Ubuntu. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1320402 Title: mdadm resyncs imsm raid in "Normal" state To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mdadm/+bug/1320402/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
