[Bug 1320402] Re: mdadm resyncs imsm raid in "Normal" state

[Martin Stjernholm]

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.

Title:
   mdadm resyncs imsm raid in "Normal" state

Status in mdadm package in Ubuntu:
  Confirmed

Bug description:
  Got an imsm raid1 which I don't boot from. Whenever bios reports the
  raid as being in "Normal" state, mdadm starts a resync of it after
  boot. If a resync already is underway (bios reports it as being in
  "Verify" state), it continues where it left off.

  This appears to be very similar to a problem in Fedora:
  https://bugzilla.redhat.com/show_bug.cgi?id=753335 It's apparently
  fixed there for some time now. (The workaround mentioned in comment 41
  in that ticket doesn't work in Ubuntu, but I guess that's due to
  distro differences in initramfs and systemd.)

  Using mdadm 3.2.5-5ubuntu4 in a fresh Trusty install.
