If anaconda is doing the update here, I guess it is because anaconda in 4.x does not have raid10 personality support. The raid10 personality is NOT the same as nested raid1+0. It is an entirely new module from Neil Brown that has a poor choice of a name imho. It does things very differently from what you expect from a nested raid1+0 array.

the update was a simple `yum update`

differently how? I expect to be striping two mirrors, all munged into one unit, without generating intermediate MD devices which has always seemed messy to me.
