Hi

i'm curious why drbd won't dispatch read request to all low level devices
and pick up the fastest response? wouldn't this be more efficient than the
local only read policy when the local storage devices are very busy, a 
degraded raid5 array doing automatic rebuild, for example?

and i think it would be even more efficient if drbd could continusely 
monitor the workload of all the low leve devices and dispatch the read
request to the idlest device only.
