Oops, you are right!

Sorry, i will try it again, to support 2 drives with dm-cow.

Great! post here the results... the dmesg in particular.
The dmesg should contain multiple lines like this "raid5:md3: read error
corrected ....."
then you know it worked.
md3 : active raid6 sdd4[12] sdl4[11] sdk4[10] sdj4[9] sdi4[8] dm-1[13](F)
sdg4[6] sdf4[5] dm-0[14](F) sdc4[2] sdb4[1] sda4[0]
14626538880 blocks level 6, 16k chunk, algorithm 2 [12/9]
[UUU__UU_UUUU]
[>....................] recovery = 1.5% (22903832/1462653888)

Khm.... :-D
It is working on something or stopped with 3 missing drive? : ^ )
(I have found the cause of the 2 dm's failure.
Now retry runs...)
Cheers,
