Is they are any way to find which pg ceph status are talking about.

Yes, but I'm guessing the

Ok. I will al
deploy
the mds, and the «new» way to do it is to use ceph fs volume.
But with ceph fs volume I didn't find any documentation of how to set the
metadata/data pool
I also didn't find any way to change after the creation of the volume the
pool.

Sorry my question was not very clear. My question was in fact in which
