Exactly.. that part doesen't work with XFS for me, although I see no
reason for it
to fail ( other than that raw partition contains raid superblock, and it
works fine with other filesystems ).
For this part you can always created degraded array with non-existant
failed disk and then mount this.
But I still have no idea how one could migrate from simple filesystem to
RAID1.
This is what I always use for this procedure.

And it works like a charm, I have built several systems using various XFS
releases with this procedures.

I don't know the code, but if i understand correctly then untill the array
is resynced it works in degraded mode and should read only from working
partition.
This is correct.
The other thing is that I'm working here with clean filesystems so no
log-reply should occur ( i think ).
But it will update it's superblock on each mount.
