You could also create two roots and two rules and have the primary osd be
the 10k drives so that the 7.2k are used primarily for writes. I believe
that recipe is on the CRUSH page in the documentation.

Hi,
you need to create 2 crushmaps, 1 for 10k && 1 for 7.2k disks.
then create 2 pools, 1pool with crushmap1 and 1 pool with crushmap2.
