For all I know it should work with a mounted partition as well. If the 
partition were not mounted or otherwise used, you wouldn't need partprobe.

And I assume "mounted" in this context means "used as drbd storage device".
I also assume that by RAID you mean some hardware RAID, because partitioning 
an MD RAID wouldn't make much sense.

Like with all these things it's a very good idea to first test it on a test 
system. Ideally identical machines, but if not available at least some VM (we 
use qemu for that and though its pretty slow, its enough for such tests). Life 
gets so much more relaxed, if you don't have to experiment around with your 
production machines :)

Regards,
Stefan
