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

[The Setlaz]

I will watch that carefully as I noticed pretty much the same !
At first, on Linux, the RAID was in Initialize state. You can power-down and up, Ubuntu will continu re-sync from where it stops (expected behavior)
After full re-sync with Ubuntu, BIOS displayed Normal status for the RAID1. 

>From there, I boot on Windows, and iRST was doing Verification from scratch. That put the RAID in Verify in the bios. 
Booting back Ubuntu started a full re-sync.

I need to check if rebooting on Ubuntu straigth after in complete the
full re-sync (when BIOS displays Normal state) triggers a new re-sync or
not.

mdadm 3.2.5  on Trusty.

Title:
   mdadm resyncs imsm raid in "Normal" state

Status in “mdadm” package in Ubuntu:
  New

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.
