Well, what should I do now ? mkfs everything and restart from scratch ?

Most likely this is your only option. First you overwrote the superblocks so the drives came in the wrong order (most likely) and then you ran a read/write fsck on it.

The thing to do is to make sure md is read only and use fsck in readonly-mode as a diagnostics tool to see if everything is right. If you get it wrong and do fsck in read/write mode it's going to change things destructively.
