I ran into similar issues a while back. In my case some of my arrays |
7 |
were using older metadata (which was required at the time to boot |
8 |
without an initramfs). I suspect that either this metadata lacked the |
9 |
info needed for a boot CD to assign the same ID, or perhaps the ID I |
10 |
was using was already allocated somehow and the boot CD chose another |
11 |
one and wrote that ID to the metadata so that it stuck. |

My solution was to move to using UUIDs or labels for everything and |
14 |
not relying on array numbering. This of course requires an initramfs |
15 |
- personally I've found Dracut to be the best one out there. It is |
16 |
just far less prone to breakage when some update causes stuff to move |
17 |
around like this. |
