[DRBD-user] MD Raid-0 over DRBD or DRBD over MD Raid-0

[Rick Rothstein]

I am planning to setup an active-active mirror over a 16-drive MD 
Raid-0 using DRBD/GFS2.
   
My original plan was to to create the raid-0 on top of 16 DRBD 
devices so that in the event of a single physical disk failure; only a single 
physical disk, and not the entire 16-drive stripe would have to be rebuilt.
   
But then I read a DRBD FAQ at:
www.linux-ha.org/DataRedundancyByDrbd
which says that
"You can stack DRBD on top of md, md on top of DRBD is nonsense, however".
   
Thanks for any advice on the best way to set things up.
