Hi raghaoty, yes there is a solution , one that is not simple ; I used it a few years ago :
The idea is to put and set a new non-RAID disk /dev/sda1 the boot from Linux CD, and make a hard copy of all the data " / " to /dev/md *, finally you have to change the partition table, the process is not simple and can cause system errors, you can also try a clean installation of OS to get the info since then RAID partitions.
