Hi someone, 

What do u mean by stripe align a file system? I used to align partition to
the 128 sector, but i think it's another matter... However i use vmfs over
my drbd resources.
I will try to move the meta-data out of the raid5-6 set, is it possible to
migrate them instead of destroying the entire file-system?
