RAID 1 OS drive "BOOT_DEGRADED=false" not working?
I'm setting up a software RAIDed boot and root desktop install. Originally I chose BOOT_DEGRADED=true during setup. But after talking with people here we wanted to change that. So I followed the instructions on https://help.ubuntu.com/12.04/server...tallation.html, shutdown, disconnected one drive, and booted. It booted just fine to the user selection screen.
mdadm against both /dev/md# entries show a degraded status, but I expected to be stopped at a recovery console. I double checked the setting is in the file /etc/initramfs-tools/conf.d/mdadm as I'd used
Code:
sudo dpkg-reconfigure mdadm
to change the setting and I wasn't sure it was permanent.
Any suggestions? Or is this not a valid setting on a mirrored drive? If so it would be nice if it wasn't available to scare newb's like me ;)

This is just a wild shot, but sometimes after changing mdadm important settings, I've seen suggestions to run:
sudo update-initramfs
(if I remembered it correctly).
See if that helps to apply the setting not to boot degraded.
Also when disconnecting disks to make a test, make sure they are synced first.
For example, a sync after the first test might not have finished yet, and if you unplug a disk for a second test it might loose the connection with the other disk and get really messed up.

I just found that my root space is marked degraded even with both drives up. Maybe that is part of the problem too?
Off to search out repair instructions.

Looks like I can't see the recovery console (black screen after disconnecting a drive after updating the initramfs and sync'ing the drives so they were clean). Guessing it'll be better to make a new thread.
