[Bug 1206238] Re: grub2 LVM support does not handle MD raid1 style mirrored volumes, completely ignoring such volumes

[Phillip Susi]

Please explicitly list the output rather than summarize it, as well as
describe your configuration.  Do you have lvm on top of md raid, or are
you having lvm do the mirroring?  Please show the output of mdadm -D on
the raid1.

Title:
  grub2 LVM support does not handle MD raid1 style mirrored volumes,
  completely ignoring such volumes

Status in “grub2” package in Ubuntu:
  Incomplete

Bug description:
  grub2 LVM support handles MD raid 4.5 and 6 but not raid1.  If you
  make your boot or root raid1 it is no longer able to even list the
  volumes.  It is therefore possible to boot your system, add a mirror,
  reboot and have no system at all.  I would guess raid1 would be a
  degenerate case of the mirror support that already exists.
