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

[Matthew Joyner]

I also have a similar problem.  Had a lot of troulbe setting uf mdadm
raid.

Have mdadm for my root partition as well as others so cannot use
workaround displayed above.

I believe the problem is somethingto di with thre initramfs not closing
down mdmon properly on shutdown.

I also have the problem of the desktop not only showing the imsm mdadm
devices but also showiing the the partitions of the raw disk devices.
Does not do it every time though.  so I end up with 3 copies of the same
partition showing up 1 for each mirrored device and one for the virtual
array.

I have two mirroed western digital red drives, using intel matrix raid.
i dual boot with windows.

I'm not sure if I should not switch back to dmraid, worked fine on
12.04.

Any suggestions, progress on this issue?

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.
