It appears something's gone to hell on my pair of mirrors which were ddf1 raid.

I can fsck all 17 filesystems with the live DVD image.

The data's all there safe and sound it appears, but something in the Marvell bios raid configuration isn't matching up with reality on the system.

I'd like to avoid a full cpio or dump of each filesystem and a rebuild.

I can mount and fsck the /dev/mapper/ddf1_disk1p# partitions fine

Any help would be greatly appreciated...

I don't know if this will help you but try to use this https://sourceforge.net/projects/boot-repair-cd/ , i manage to fix my raid0 boot on ubuntu 16.04 i don't know if it will work on 18.04. Right now i want to upgrade from 16.04 to 18.04 i hope it will not blow my raid0 boot
