Exactly.. that part doesen't work with XFS for me, although I see no reason for
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

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
I think this:
harybda:~# cat /proc/mdstat
Personalities : [raid1]
read_ahead 1024 sectors
md0 : active raid1 sdb6 sda6
714752 blocks [2/1] [U_]
[>....................] recovery = 2.7% (19456/714752)
would mean that freshly addedd sdb6 part is not operational ( "_" as opposed
to "U" ) until it has been fully resynced.
The other thing is that I'm working here with clean filesystems so no
log-reply should occur ( i think ).
