BTW, there is - even with current kernels - no speed gain in using RAID1 -

I don't think I believe that - you can see the reads alternating drives by
watching the lights.
Indeed, there is a patch linux-2.6-dm-mirroring.patch in Centos5.2
kernel sources which implements a proper body of choose-mirror()
function.
Which also explains why, once my mirror was corrupt, that a new problem
would show up every few weeks even after the cause (bad RAM) was fixed.
