Hi; this is the closest bug I found to my problem. I did a clean install of 11.10 Oneiric Ocelot (Kubuntu) on a machine which has a degraded software RAID disk (but not onto that disk), did not install mdadm, and it booted fine. I then merely installed mdadm but did not attempt to activate the drive, and I get the initramfs / busybox screen. Here are screenshots of dmesg, and of grepping for failures: http://imgur.com/a/NEr12
Let me know if there are any experiments I can do. Thanks. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/778520 Title: install on degraded raid1 does not boot, drops to initramfs shell To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/778520/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
