[Openstack-operators] [neutron] Liberty - DHCP ports keep going to BUILD state

[Christopher Hull]

HI all;
Trying to create DHCP on the Public network.  This had been working, but
now all of a sudden the ports are set to BUILD instead of AVAILABLE.

I did a cheat in MariaDB and discovered that something somewhere keeps
setting DHCP to BUILD.   Any ideas?


*MariaDB [neutron]>  update ports set status='AVAILABLE' where id
='37cc930c-6ad3-4355-8ff5-6b75e131c998';*

*Query OK, 1 row affected (0.05 sec)*

*Rows matched: 1  Changed: 1  Warnings: 0*


*MariaDB [neutron]> select status, id  from ports;*

*+---+--+*

*| status| id   |*

*+---+--+*

*| BUILD | 0ebbaf42-6bd9-4853-b041-e00f3da4dd89 |*

*| AVAILABLE | 37cc930c-6ad3-4355-8ff5-6b75e131c998 |*

*+---+--+*

*2 rows in set (0.00 sec)*


*MariaDB [neutron]> select status, id  from ports;*

*++--+*

Re: [Openstack-operators] [neutron] Liberty - DHCP ports keep going to BUILD state

[Christopher Hull]

This is just damn strange.  All of a sudden (well, for the past few weeks),
I CAN NOT create ANY port on the public network.   Just tore down and
recreated the public net from scratch.   What's going on here!!!

It's stuck trying to create the DHCP agent's port.  This is why it's stuck
in BUILD.  Infinite loop.BTW, the Compute node is at 172.22.10.99.
 Maybe I should just change that.  But it would be really nice to know what
changed and why this is happening.

[Openstack-operators] Fast Forward Upgrades

[David Medberry]

Some good discussion at the Summit (right now) about Fast Forward Upgrades.

Including some concerns that nova-compute INTENTFULLY fails if greater than
N-1.

More details are appearing in the etherpad.

This convo is VERY well attended by MANY openstack devs. Very heavy dev
room.

https://etherpad.openstack.org/p/SYD-forum-fast-forward-upgrades

and this is in the Operator session in the Dev Forum.

[Openstack-operators] [Openstack][Nova][Operators]

[Amit Kumar]

Hi All,

I have installed Openstack Pike with Openstack Ansible.

Earlier I was working with Newton release. But with Pike release, I am
noticing that Nova schedule is in force even when I am providing
availability zone with a specific compute node. For the initial set of VMs,
it is honouring availability zone request while creating VMs but while
creating last set of VMs, it is putting VMs on other compute nodes,
probably the nodes which are having more resources. So, my question is that
does Pike and Ocata releases allow over commitment of CPU/RAM/Disk
resources or not? If they do so, then what are the parameters which will go
in the configuration files to make over commitment work? I strictly want to
enforce that VM be instantiated on the host I mention in availability zone.

Regards,
Amit
