Re: [Openstack] [Design] Why/how object storage(Swift) better than scale-out NAS?

[Kuo Hugo]

*REF :*
http://www.quora.com/What-features-differentiate-HDFS-and-OpenStack-Object-Storage
by ChunkThier

While there are some similarities between HDFS and Openstack Object Storage
(Swift), the overall design of the systems are very different.

1.  HDFS uses a central system to maintain file metadata (Namenode), where
as in Swift the metadata is distributed and replicated across the cluster.
Having a central meta-data system is a single point of failure for HDFS,
and makes it more difficult to scale to very large sizes.

2.  Swift is designed with multi-tenancy in mind, where HDFS has no notion
of multi-tenancy

3.  HDFS is optimized for larger files (as is typical for processing data),
where Swift is designed to store any sized files.

4.  Files in HDFS are write once, and can only have one writer at a time,
in Swift  files can be written many times, and under concurrency, the last
write wins.

5.  HDFS is written in Java, where Swift is written in Python

TLDR: HDFS is designed to store a medium number of larges files to support
data processing, where Swift is designed as a more generic storage solution
to reliably store very large numbers of varying sized files.

(HDFS Architecture information attained from
http://hadoop.apache.org/hdfs/do...
)

[Ying Chun Guo]

Hi,


I'm pleased to announce the first IRC meeting of OpenStack I18n team will
be held on
Thursday, 4th July at 0100 UTC .


The OpenStack I18n team will take responsible for the I18n and L10n of
OpenStack.
Our mission is to make OpenStack ubiquitously accessible to people of all
language
backgrounds, by providing a framework to create high quality translations,
recruiting
contributors and actively managing and planning the translation process.


We want people all around the world who are interested in I18n or OpenStack
can join.
The work scope of this team includes:
   translation of documentation, messages, websites, and etc.
   I18n tests
   tools maintenance and enhancements


In order to facilitate people to join the discussion, the meeting will be
held on each Thursday,
but alternately between two different times: Asia and America friendly
time, and
Europe and India friendly time.


For more details, please look into

[Openstack] Minutes from the Technical Committee meeting (July 2)

[Thierry Carrez]

The OpenStack Technical Committee ("TC") met in #openstack-meeting at
20:00 UTC yesterday.

Here is a quick summary of the outcome of this meeting:

* In order to simplify its taxonomy and recognize more types of
contributions, the TC defined official 'Programs' by adopting the
following motion:

"""
'OpenStack Programs' are efforts which are essential to the completion
of our mission. Programs can create any code repository and produce any
deliverable they deem necessary to achieve their goals.

Programs are placed under the oversight of the Technical Committee, and
contributing to one of their code repositories grants you ATC status.

Current efforts or teams which want to be recognized as an 'OpenStack
Program' should place a request to the Technical Committee, including a
clear mission statement describing how they help the OpenStack general
mission and how that effort is essential to the completion of our
mission. If programs have a goal that includes the production of an
'Integrated' deliverable, that specific deliverable would still need to
go through an Incubation period.

The initial Programs are 'Nova', 'Swift', 'Cinder', 'Neutron',
'Horizon', 'Glance', 'Keystone', 'Heat', 'Ceilometer', 'Documentation',
'Infrastructure', 'QA', 'Oslo', 'Trove' and 'Ironic'. Those programs
should retroactively submit a mission statement and initial lead
designation, if they don't have one already.

The TC asks that the chair modifies the charter accordingly, including
replacing the word "Projects" by "Programs" where appropriate.
"""

Our project documentation on the wiki will be updated accordingly.

[Openstack] [OSSN] [OSSG] Nova Baremetal Exposes Previous Tenant Data

[Clark, Robert Graham]

Nova Baremetal Exposes Previous Tenant Data
-

### Summary ###
Data of previous tenants may be exposed to new ones when using Nova Baremetal

### Affected Services / Software ###
Keystone, Databases

### Discussion ###
Nova Baremetal is intended for testing and development only, it is not intended 
to be production ready. Experience has shown that despite that warning the 
OpenStack community is keen to embrace new technologies and deploy at-risk. 
This OSSN serves to signpost some of the risks.

Without secure boot, and without full openflow hardware networking during the 
boot process, it is impossible to trust multiple tenants on baremetal at all - 
because the vectors for attack are so low level that instances may be running 
in a virtual environment and unaware of it, with the virtual environment 
capturing secrets, forcing entropy pools to be predictable and other such 
hostile behaviour.

### Recommended Actions ###
Do not use Nova Baremetal where secure separation of tenants on hardware is a 
requirement without a full verifiable boot chain and network hardware.

### Contacts / References ###

Hm... So, it may indicate that nobody has used stable release (Grizzly)
from CloudArchive on Ubuntu12.04 with VLAN manager, right?

About Targeting you meaning using 'ubuntu-bug' tool?

This issue is fixed in the current Openstack development release Havana.

The reason you are seeing this in Grizzly, is because nobody has
backported this fix (or even targeted it) to this release.

Unless someone does this, you will continue to see this in Grizzly
releases from source, or any distribution.

Hope this helps.

Re: [Openstack] Cloud Archive repository

[Daviey Walker]

Hey,

Based on what I have read from the bug, this issue indicates that few
people have had need to disassociate a network from a project in vlan
mode in Grizzly.  This issue is present in any distribution of
OpenStack, including deploy from source.

We know that many users are using the Grizzly pocket of the Ubuntu
Cloud Archive with 12.04.  Looking at the bug, I see that Michael
Still has added the tag - "grizzly-backport-potential", which means
that it is now on the radar for the Stable Team to look at.

I don't think this was done previously, as it wasn't clear if it was a
Havana specific issue.

Hope this helps.

Re: [Openstack] heat-watch problem

[Michaël Van de Borne]

As Steven told me on IRC, the problem was that the user associated with 
my EC2 creds had the heat_stack_user role in keystone.
This role is intended to be used only for the in-instance users, created 
as part of the stack, not real human users. This is described in policy.json


thanks Steven,

btw: any idea about the first problem?

the service tenant. The config files of engine, cloudwatch and boto

This is due to https://bugs.launchpad.net/heat/+bug/1196618

Which is now fixed in heat master, and it is unrelated to the heat-watch
authentication failure

As confirmed on IRC (repeated here for the benefit of others), the reason
is that your user associated with the ec2 keypair has the "heat_stack_user"
role, which is intended to be reserved for users created as part of a heat
stack (where the credentials are deployed inside an implicitly untrusted
instance).

The clues are (from api-cloudwatch.log)

2013-07-03 16:12:13.358 27398 INFO heat.api.aws.ec2token [-] AWS
authentication successful.

which proves the ec2 keypair and resulting signed request via boto is OK

Then we get "User is not authorized to perform action" response, but with
no corresponding log message in the engine.log - so it's the policy.json
rules which limit access to in-instance "heat_stack_user"s which is
preventing access, here's the rule in the /etc/heat/policy.json:

"deny_stack_user": "not role:heat_stack_user",

...

"cloudwatch:DeleteAlarms": "rule:deny_stack_user",
"cloudwatch:DescribeAlarmHistory": "rule:deny_stack_user",
"cloudwatch:DescribeAlarms": "rule:deny_stack_user",
"cloudwatch:DescribeAlarmsForMetric": "rule:deny_stack_user",
"cloudwatch:DisableAlarmActions": "rule:deny_stack_user",
"cloudwatch:EnableAlarmActions": "rule:deny_stack_user",
"cloudwatch:GetMetricStatistics": "rule:deny_stack_user",
"cloudwatch:ListMetrics": "rule:deny_stack_user",
"cloudwatch:PutMetricAlarm": "rule:deny_stack_user",
"cloudwatch:PutMetricData": "",
"cloudwatch:SetAlarmState": "rule:deny_stack_user"

As you can see, the policy only allows users with the heat_stack_user role
to access the PutMetricData action, which is the only action required by
the in-instance user (for the cfn-push-stats agent)

So no "real" users should ever have the "heat_stack_user" role, it should
be reserved for use inside heat.

[Openstack] possible usage information

[Randy S]

Hi all,

I have been reading up on openstack as I am completely new to this. I have set 
up some test systems according to manuals found here and there.

Now, I have a question about the possible use of openstack storage.
I have seen that the normal provisioning of storage is meant to be for vm's 
created within openstack itself. This can then be block storage (cinder) or 
object storage.

Can somebody tell me if it is possible to use openstack to provision the same 
kind of storage to physical servers which are otherwise in no way connected to 
openstack or virtual machines created in systems like vmware?

I hope somebody can asnwer me this and maybe point me the way to test something 
like this.

Thanks in advance,

Rgds,

Randy

Hello guys, I have a Controller node and a Compute node with grizzly installed 
and working fine, but the problem is, I'm installing two more computes nodes 
but at both I'm getting error at nova (error attached). I made some researches 
through the google and I saw some people talking about running an apt-get 
update / apt-get upgrade at the Controller node and Compute node. My point is, 
is safe to run this update/upgrade steps? My working controller and compute can 
stop working (break?)

Probably you have an older nova version running in one of the compute-nodes,

Re: [Openstack] Updating OpenStack

[Calvin Austin]

I experienced the same thing just yesterday. the python-nova package (on
ubuntu) has api changes in dot dot versions, 1.47 brought in a new db call
that the server doesn't know about.

I ended up downloading the same python-nova package on the new compute node
so they could talk

python-nova_2013.1-0ubuntu1_all.deb

Hi Guilherme,

To ensure that all settings match up correctly, it's advised to copy the 
nova.conf from your Controller node, or the Compute Node that works, to each 
new Nova node

[Openstack] Two hypervisors instead of one

[Simon Marchuk]

Hi, I've installed Grizzly on Debian Wheezy and when I get hypervisors list

# nova hypervisor-list

I get two hypervisors
+++
| ID | Hypervisor hostname|
+++
| 1  | myriads-serv1.myriads.irisa.fr |
| 2  | myriads-serv1.myriads.irisa.fr |
+++
when I have configured only one.
Is it ok?


At the same time my instances get stuck in state building/scheduling I
don't know if it can be reason.

Thanks in advance.

In your place I just download the same nova packages to your new compute nodes 
as you got on the first one as Calvin said! Upgrading your existing network 
node and compute node can result in disaster :)
Good luck

Probably you have an older nova version running in one of the compute-nodes, 
and probably that's  why you have UnsupportedRpcVersion exception!

Re: [Openstack] Updating OpenStack

I made the download from python-nova_2013.1-0ubuntu2_all.deb and installed
it, then I made the apt-get install nova-compute-kvm but I'm still getting
the same error, am I doing something wrong?

Thank you guys.

Re: [Openstack] Updating OpenStack

[Calvin Austin]

downgrading to python-nova was the last thing I did, apt-get might fix you
to the latest one.

You can check file
/usr/lib/python2.7/dist-packages/nova/conductor/rpcapi.py

If it mentions 1.47 in the API version history you have the later
python-nova, when you downgrade it will ask you if its ok.

calvin

It is showing the 1.47, i'm lokking through the internet how to install the
packages that match with my working compute node. I still have no clue how
to do that :(
