Hi, I had a similar issue on Friday: a disk failed on a raid 1 ubuntu 9.10 system. After shutdown I removed the failed disk and added a new one. While booting I got an initramfs shell, as in your case. In my case the instructions on screen said that the system requested me whether to boot with a degraded array (y/N) or not and that and I did not answer quickly enough to the question, so, after timeout, it brought me the initramfs shell. To be honest I never saw that question on screen and the reason was that the splashscreen covered it. So I just rebooted and pressed 'y' some times when the splashscreen appeared and then the degraded boot started as expected. After that I had to manually partition the new disk (I have 2 different raid1 systems, one for /boot, one for / ) and add each partition to the raid system: sfdisk -d /dev/sda | sfdisk /dev/sdb # partition sdb as sda mdadm /dev/md0 -a /dev/sdb1 # add sdb1 to the raid1 system md0 (/boot) mdadm /dev/md1 -a /dev/sdb2 # add sdb2 to the raid1 system md1 (/) WARNING: this worked for my setting so don't take them as general instructions! If you have a mirroring setup than you could need just to add sdb1. After this the new disk sdb started syncing as expected.
