Hello,

actualy i have drbd configured as:
master/slave
meta-disk: internal
backd blockevice is sw raid.. /dev/md0

Now everything is working fine, but due to performance issue i need to
migrate form sw raid6 level to raid5..

I have no problem with sw raid online resize. But when resize operation
will finished, then backing device's size will grow up +250GB

There is no chance to resize both nodes simultaneously with finish in
the same time..

How will drbd handle this situation? when one backing device will be
bigger then second one. 

thanks J.Vitek
