[Bug 1044598] Re: Grub does not mount raid 5

[Dmitrijs Ledkovs]

By the time you can press "S" to skip waiting, you are already seeing
plymouth. The actual raid assembly is usually done by the package mdadm.

Can you please run $ sudo apport-collect 1044598 to collect relevant
details about your raid array.

I am assuming that you are using software raid via mdadm, and not
fakeraid / external metadata raid via dmraid.

Title:
  Grub does not mount raid 5

Status in “mdadm” package in Ubuntu:
  Incomplete

Bug description:
  I boot from /dev/sda  which contains win7, hp recovery, etc. My raid 5
  is on /dev/sdb, /dev/sdc and /dev/sdf and is mounted as /media/data.
  During the boot process Ubuntu halts with the message that there is no
  /media/data and I normally press "S" to skip waiting. Then I need to
  mount the disk either with a mount command in a terminal winds or the
  Disk Utility. It would be great if grub could start and mount my raid
  5.
