This is a very old LP bug, but for completeness it worth mentioning here
that recently some patches were merged on initramfs-tools and
cryptsetup, that allow a good experience booting with LUKS-encrypted
rootfs on top of a degraded RAID1 array; for details, please check:
https://bugs.launchpad.net/
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1003309 and
https://bugs.launchpad.net/ubuntu/+source/cryptsetup/+bug/251164 had the
info I needed to fix my problems with encrypted RAID1 not booting in
degraded mode.

My server was in 8.04 LTS, having a raid 1 setup with 2 mirrored harddisk.
I have tested, if I unplug one of the disk, the raid 1 was working fine.
Sadly, after upgraded my system to 10.04.1 LTS, if I unplug one of the
disk and boot, the raid 1 become inactive.

Yeah, isn't 8.04 an LTS edition?
My 8.04 Desktop machine suffers from this problem. I think I got it
fixed by adding the command to assemble the arrays degraded to the
initramfs 'local' script, but finding what needed to be done was a real
PITA and I'm sure others will continue to hit this issue.
Is this bug still present? I've installed a fresh 8.04.2 amd64 in a
VirtualBox 2.1.2 with three SATA harddrives. When i switch off a drive,
kernel is loadding but at the end the raid arrays are stopped and the
system is unusable.

Dustin, thank you for your quick answer and tips.
It took me a while to test it, as I have an encrypted RAID 1 array with
LVM, and things are not that straightforward with that setup.
So far I have been using one of the tricks described in this thread
earlier (ie. edit /etc/udev/rules.d/85-mdadm.
You should not need to reinstall.
To solve this, you need to:
a) live upgrade all packages (specifically, you need to upgrade grub,
mdadm, and initramfs-tools)
b) install grub to the raid (for instance, if /dev/md0 provides your
/boot directory, you can do "grub-install /dev/md0")
Cheers,

It seems that the issue is now fixed in Intrepid, and also backported to

I have been fighting installing a RAID setup with 8.04 + GRUB for about
