I had a similar problem resulting from a similar upgrade. |
| 5 |
It was because of the order of the drives, which was different in the |
| 6 |
BIOS (as seen by grub) and the Linux kernel. |

mdadm should not care and it should be able to re-assemble the array no |
| 8 |
matter what the partitions are named (sdc|d instead of sda|b in my case) |
| 9 |
Some of the arrays were out of sync (I had mounted one of the raid-1 |
| 10 |
partitions separately for making a backup, etc) - booting using knoppix |
| 11 |
(or using a simple recovery ramdisk) allowed me to re-assemble them. |
| 12 |
Reboot, done. |

It can be useful to keep a ~200MB partition to install something small |
| 14 |
like Slackware/Busybox for emergencies, this would allow you to boot on |
| 15 |
a single drive and see what the kernel and mdadm tools make of your |
| 16 |
array. |
| 17 |
Hope this helps! |
