Hi Frédéric, The curiosity of Albert's cluster is that (msgr) v1 and v2 are present on the mons, as well as on the osds backend. But v2 is absent on the public OSD and MDS network The specific point is that the public network has been changed. At first, I thought it was the order of declaration of my_host (v1 before v2) but apparently, that's not it.
