[Bug 120375] Re: cannot boot raid1 with only one disk

[no!chance]

Full ack to miguel. Why is somebody using a raid1 on his system. Does he
want to have trouble, if a disk fails, or does he want a running system
and to be informed about a hardware failue? Ubuntu raid is useless! The
"conservative" mode is useless! If i had a 4 disk RAID1 system or a
RAID5 with a spare disk and ONE fails. Is it useful to stop the boot
process???

I have the same issue on my new system. First, I had one disk and
decided to upgrade to software raid. With the second HD, I created a
degraded raid1, copied the contents of the first disk to the second, and
wanted to add the first disk to the raid. Ubuntu drops me into the
shell.  :-(   And in spite of booting with a live CD and adding the
first disk to the raid, the system refused to boot.

Because it is a new system without any data on it, I will do a new
installation with debian or suse. For my home server, I will see.
