Reuben,
What chunk size did you use?
I can't even get mine to get past this part:
p34:~# mdadm /dev/md3 --grow --raid-disks=7
mdadm: Need to backup 15360K of critical section..
mdadm: Cannot set device size/shape for /dev/md3: No space left on device
Justin.
Just whatever the system selected for the chunk size, ie I didn't specify it
myself ;)

I was working on md1 when I filed the email earlier.
I wonder if the chunk size is left as-is after a --grow, and if this is optimal
or not or if this could lead to issues...
