I believe it has been, yes. I think we've even had a patch out for
 it. I haven't looked to see if it's got into 3.10.

Yes, there is a patch but as far as I've seen it didn't hit 3.10 (yet).
I'll repost it immediately.

Thanks for reminding me on that,

 Thanks for the help,

 dmesg | tail says:

 Isn't it possible to convert raid level to raid5?

   Yes, it should be possible. It looks like the kernel's got a
 problem with it, which is odd because 3.9 should know about RAID-5.


 Wasn't there some issues that the kernel or tools wanted 4 disks when
 converting to raid5?

Yes, you were right! Adding another drive to the array made it
continue without errors. Is this already reported as a bug?
