Setup CephFS production cluster

Since we finished testing CephFS it's time to setup the production cluster based on the following specs:

3x MON/MDS servers based on VM type: Standard_DS13?
10x OSD servers with 4x 6TB OSD instances each based on VM type: Standard_DS14
Every CephFS node should have a network interface in 'subnet1' for the workers
The 6TB are 6x 1TB disks as striped LV with LVM (striped so we don't hit the IO limit per disk)
