I assume that you want the cephfs_metadata pool to be located on the SSD.
The crush rule uses host based distribution, but there are only two
hosts available. The default replicated rule uses osd based
distribution, that's why the other pools aren't affected.
You have configured the default number of replicates to 3, so the ssd
rule cannot be satisfied with two host. You either need to put the
metadata pool on the HDD, too, or use a pool size of 2 (which is not
recommended).
