I have the same problem with mdadm/raid-1, if you do not limit the speed in
the speed_limit_min paramter, it will starve the I/O from all other processes
and result in the same problem you are having.
(ie. the default) and this still caused all process to hang in D-state. Only
lowering speed_limit_max helped to make the system responsive again.
But for me I'm not sure about the reconstruction-- this happens for me during
a raid verify/check.This was also the case for me, during a raid verify/check.
