Re: [Openstack] [openstack][neutron] problems accesing metadata on OVS VLAN mode (havana)

Hi Alejandro, As we've already discussed the topic over IRC, let me add something else on your setup: - no dhcp agent, no l3 agent - IP configuration injected into instances (I'm disclosing this information since it's already been disclosed on IRC whose logs are publicly accessible anyway) Commen

[Openstack] [openstack][neutron] problems accesing metadata on OVS VLAN mode (havana)

Hi guys, we are deploying: havana + OVS on vlan mode + neutron using this EXACT production schema : http://docs.openstack.org/network-admin/admin/content/figures/2/figures/under-the-hood-scenario-2-ovs-compute.png Since we are using this schema, im gonna reffer about devices as they are named in

Re: [Openstack] [rhos-list] dns problem for instances

Thanks for all the reply, as Paul said, the dnsmasq version doesn't appear to be the issue here. I also tested dns between 2 different VM subnets, instances can ping each other across subnets, they can also reach dns server of the other subnet. But hostname can't be resolved across subnets. Al

On a side note, I would love to hear some experiences with GlusterFS as well. We will move to Havana soon and I need to plan the new infrastructure... .a. On Fri, Nov 15, 2013 at 8:45 PM, Vinay Venkataraghavan wrote: > Razique, > > Can you share the type of work loads you ran on Ceph and some pe

Re: [Openstack] NovaException: Unexpected vif_type=binding_failed

Thanks for the hint Yang. I checked the o/p of neutron agent-list and all agents looked good. Then I looked in the agents table in DB and the bridge_mapping was empty. | 08d4544f-d71e-4df8-a2fe-3e998f307280 | Open vSwitch agent | neutron-openvswitch-agent | N/A| localhost.localdomain |

Re: [Openstack] about block storage

iscsi is sufficiently performant. I have done extensive testing between iscsi and nfs etc for VM storage. iscsi is very very fast. Ofcourse, the caveat is how your network is also configured. You should definitely perform all the tests that have been recommended in this thread to determine where t

Re: [Openstack] about block storage

Razique, Can you share the type of work loads you ran on Ceph and some performance numbers. I considered Ceph for a large private cloud that we were building but never got to it. I ended up using iscsi and nfs which were great. I would love to hear more about Ceph performance numbers especially i

Re: [Openstack] [neutron] neutron-ovs-cleanup: which distros require manual invocation?

Hi Nick: The Red Hat packages include a service script (I assume at /etc/init.d/neutron-ovs-cleanup) that invokes /usr/bin/neutron-ovs-cleanup automatically at the appropriate time. I was asking whether there was an equivalent service script in Ubuntu that invokes /usr/bin/neutron-ovs-cleanup on b

I finally found the error it's generating. Not from the log files through, but from Horizon UI. Error: Failed to launch instance "test2": Please try again later [Error: Timeout while waiting on RPC response - topic: "network", RPC method: "get_instance_nw_info" info: ""]. Now, how do I fix RPC ti

Re: [Openstack] about block storage

I would test the effective network bandwith with iperf. Then I would test the speed of the cinder backend by mounting the volume locally and running, for instance, iozone. Finally, I would test the performance of the iSCSI backend by mounting the volume on the compute node (or another node) via i

Re: [Openstack] about block storage

ok, I'd try to bench the I/O locally, then through the network, on the block device,and see when the big difference comes from. - Razique On 14 Nov 2013, at 18:30, Jitendra Kumar Bhaskar wrote: > Please make sure from block storage to switch and from switch to compute > node connectivity is in GB

In the nova.conf and neutron.conf enable verbose=True, Debug=True. Also, look into logging configurations in the same files. -- Trinath Somanchi - B39208 trinath.soman...@freescale.com | extn: 4048 From: Krishanu Dhar [mailto:rony.k...@gmail.com] Sent: Friday, November 15, 2013 4:27 PM To: OpenS

[Openstack] Deletion data from db

Hello, In nova database lot of data like quotas, reservations, security_groups and other are not phisically removed but are marked as deleted. So for example after tempest run on such infrastructure there is a lot of entries marked as deleted. So I' thinking for what all that data is stored i
