Description Michele Baldessari 2021-06-11 15:54:35 UTC 
Description of problem:
After a successful 16.1->16.2 update the overcloud has every entry twice in /etc/hosts. So we have:
# START_HOST_ENTRIES_FOR_STACK: overcloud
172.17.1.60 compute-0.redhat.local compute-0
172.17.3.34 compute-0.storage.redhat.local compute-0.storage
172.17.1.60 compute-0.internalapi.redhat.local compute-0.internalapi
.....
10.0.0.150  overcloud.redhat.local
# END_HOST_ENTRIES_FOR_STACK: overcloud
# BEGIN ANSIBLE MANAGED BLOCK
172.17.1.60 compute-0.redhat.local compute-0
172.17.3.34 compute-0.storage.redhat.local compute-0.storage
172.17.1.60 compute-0.internalapi.redhat.local compute-0.internalapi
172.17.2.135 compute-0.tenant.redhat.local compute-0.tenant
192.168.24.20 compute-0.ctlplane.redhat.local compute-0.ctlplane

So we have all entries under END_HOST_ENTRIES_FOR_STACK:overcloud and then again all entries under "BEGIN ANSIBLE MANAGED BLOCK"
