Testing rack awareness
Is there a way to check if the rack awareness is working ?
I seem to configure it right, but  when I run a fsck on my files written, it still shows  "Number of racks:               1"
What I am looking for is a simple command which can tell me if rack awareness is working or not ?
Thanks in advance
