Linux RAID10 with

Will layout data like this:

   disk0   disk1   disk2   disk3
     A       A       B       B
     C       C       D       D
     E       E       F       F

You have removed disk0 and disk1, so A,C,E don't exist
any more.  You should get IO errors when you try to access
that data.
There is nothing that can be recovered, so the drives remain
as spares.

You're right - sorry. I better should read my own logfiles tho. Somehow 
removing a single disk and readding it mixed up with the raid device 
numbering - which I didnt notice at first.
