RAID modules loaded too late in the boot sequence

[Gerald Villemure]

Binary package hint: initramfs-tools

If you get kernel messages like this:
      md: personality for level 1 is not loaded!

And when you run:
   mdadm --detail /dev/md0
You get:
   State : active, Not Started

This is most likely cause by the fact that the RAID1 module is loaded AFTER the array is brought online. This happens to me mostly on older (slow) computers.

To fix, create a file in this folder:
  /etc/initramfs-tools/scripts/init-top

Call the script what you like and put something like this in the file:

#!/bin/sh
modprobe raid1

You should be okay after that.

Hope this helps,
Gérald

May be better just to add raid modules to /etc/initramfs-tools/modules.
Workaround:
1) boot to rescue mode using install CD;
2) execute:
echo "$RAID_MODULE_NAME" >> /etc/initramfs-tools/modules
dpkg-reconfigure linux-image-$YOUR_KERNEL_VERSION
3) reboot.
