Little bit a ceph beginner here.

I followed the directions from Sébastien Han and built out a ceph crushmap with HDD and SSD in the same box. There are 8 nodes each contributing an SSD and an HDD.

I only noticed after putting some data on there I goofed and put a single HDD in the SSD group and one SSD in the HDD group.

My thought was to push a new crushmap where this is fixed, it would spawn a self heal, and no data would be endangered as one would expect from a clustered storage and from all I've read.

I just wanted some quick feedback from someone who has done this that I would not be risking data.
