Hi,

Not sure I fully understand your issue, and to tell the truth my memory is quite bad so not sure if I can recall how things worked at Ussuri time.

Do you have the resource providers for your segments in placement?

if not, please check if Neutron can acces placement API (check the neutron.conf's placement section, check the log if there are Placement Client Errors or similar suspicious things)

As I see from the code if the aggregates are created the resource providers and inventories should also be created.

Hi neutron experts

Have a cloud built with multiple network segments (RPN) . (kolla-ansible, openstack ussuri),
things are running OK (on the network level):

networks have DHCP agents ok (os network agent list --agent-type dhcp --network $networkID )

all network segments are listed in Host Aggregates

BUT if I run through all the existing segments ,
NONE have a (compute service) inventory declared for each segment IPv4 subnet
i.e
os resource provider inventory list $segmentID
returns no output. (official doc on RPN says this should exist)

What feature may not function if this inventory is missing ?

I don't quite understand what role this IPv4 subnet compute service inventory plays here (during placement? port declaration ?)

thanks
Andrew
