Re: [Openstack] Instance cannot get any ip address

Hi, thanks for your helps! After I enabled DHCP, my instance can get private ip address now. However, I find that my 2 instances still cannot ping each other successfully. So I want to know if I need to config a DNS server for them? Thanks very much! From: 严超 [mailto:yanchao...@gma

Hi Steve, Thanks for your reply. What I want to do is to define alarm action which will trigger heat to launch a stack, like executing "heat stack-create...". And by doing this, once the condition of the alarm is met(alarm in ceilometer is triggered), the heat stack will automatically created/la

Re: [Openstack] [neutron] Network node can't see external network

Hi, After sorting this out, I found out that my VMs weren't able to get an IP via DHCP. After a lot of troubleshooting, I fixed it by enabling IP forwarding (net.ipv4.ip_forward=1) in the compute node (which is actually not mentioned in the documentation: http://docs.openstack.org/icehouse/

Yes, it's possible just like a volume from Cinder. But it still exists some works todo. We need to pass iops/bw throttle value in via config or flavor metadata. If you want to get it as quick as possible, you can add some hack codes like this: tune_items = ['disk_read_bytes_sec', 'disk_rea

[Openstack] Swift questions

Hello, Some questions on new and old features of Swift. Any help would be great:) Some are very basic, sorry! 1. Does Swift write two copies and then return back to the client in the 3 replica case, with third in the background? 2. This again is a stupid question, but eventually consistent for an

BTW, I also have a change in review that enhances the existing autoscaling.yaml example template to include the webhooks in the stack outputs. This example has the additional virtue of including the Ceilometer alarms as well as the scaling actions they invoke. See https://review.openstack.org

Re: [Openstack] Swift questions

Thanks Paul:) For the container part, you mentioned that node(meaning object server?) contacts the container server. Since you can have multiple container servers, how does the object server know which container server to contact? How and where the container gets updated is a bit confusing. With c

Re: [Openstack] Swift questions

Just to clarify the first answer. Everything Paul said is correct: with 3 replicas, Swift requires that 2 (a quorum) are successful before a success can be returned to the client. But, assuming there isn't any current issue in the cluster (ie it's healthy), then all replicas will be written befo

Re: [Openstack] Swift questions

Yup, thanks for the great explanation:) Another question, though related: If there are three regions, and two get "split", there is now a partition. Both the split ones can talk to the third, but not to each other. A PUT comes into one region, and it gets written to the local site. Container info

Re: [Openstack] Swift questions

Yup, this is a totally possible failure scenario, and Swift will merge the data (using last-write-wins for overwrites) automatically when the partition is restored. But you'll still have full durability on writes, even with a partitioned global cluster. --John On Aug 27, 2014, at 10:49 AM, M
