I just experienced this problem. Through the "md: array md0 already has disks!" error. Through the spam, if you wait 60s (or whatever the timeout is), you will be dropped to the initramfs shell. You can't see it though through the "already has disks" error 100 times per second. But, I typed 'mdadm --stop /dev/md0' and this stopped the spam! Surprisingly, /dev/md0 existed, and was fine! (though degraded, but I expected that because one drive had failed)
To repeat, I ran 'mdadm --stop /dev/md0' and *after* I ran that, /dev/md0 still existed and was fine. So, it appears that mdadm is trying to create /dev/md0 *twice* and obviously fails the second time (repeatedly). -- mdam software raid fails to start up on reboot https://bugs.launchpad.net/bugs/188392 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
