[openstack-dev] [Sahara][Doc] Overview and Architecture images in docs

[Sharan Kumar M]

Hi all,

There was a discussion previously stating that the Sahara overview image
http://docs.openstack.org/developer/sahara/overview.html and the
architecture image
http://docs.openstack.org/developer/sahara/architecture.html pretty much
convey the same message. So will it be nice to strip off the overview image
and have only the architecture image?

In that case may be we could ameliorate the architecture diagram.

Thanks,
Sharan Kumar M

[openstack-dev] Unusual behavior on committing a change

[Sharan Kumar M]

Hi all,

I am getting some weird things when I try to submit a patch for review. May
be I am doing something wrong.

I cloned the repo, setup git review and setup my gerrit username in git
config. I updated an image in the docs/source/images directory and
committed. After I commit, I get the git status report as

Your branch and 'origin/master' have diverged,
and have 1 and 1 different commit each, respectively.

When I see the log, the last commit is authored by
jenk...@review.openstack.org with the same commit message as mine. The
author name is supposed to be mine right? The last time I submitted for
review, the commit message had my name as author.

Could someone help me out with this issue?
Thanks,
Sharan Kumar M

[openstack-dev] [Sahara] Verbosity of Sahara overview image

[Sharan Kumar M]

Hi all,

I am trying to modify the diagram in
http://docs.openstack.org/developer/sahara/overview.html so that it syncs
with the contents. In the diagram, is it nice to mark the connections
between the openstack components like, Nova with Cinder, Nova with Swift,
components with Keystone, Nova with Neutron, etc? Or would it be too
verbose for this diagram and should I be focusing on links between Sahara
and other components?

Thanks,
Sharan Kumar M

[openstack-dev] [Sahara][Doc] Features overview suggests Cinder to increase reliability

[Sharan Kumar M]

Hi all,

In this bug https://bugs.launchpad.net/sahara/+bug/1371360 its said that
Cinder itself has replication and using it with HDFS will increase
replication even more. That said, will mentioning this in the documentation
and also stating that it makes sense to use Cinder when replication factor
for HDFS is 1 fix the bug?

Thanks,

[openstack-dev] [Sahara][Doc] Updating documentation for overview; Needs changing image

[Sharan Kumar M]

Hi all,

The bug on updating documentation for overview / details
https://bugs.launchpad.net/sahara/+bug/1350063 also requires the changing
of image openstack-interop.png. So is there any specific tool used for
creating the image? Since I am working on fixing this bug, I thought I
could also update the image.

Thanks,

[openstack-dev] [Sahara] Networking Service for Sahara

[Sharan Kumar M]

Hi all,

What is the default networking service for Sahara? Is it Nova Network or
Neutron? I referred this page
http://docs.openstack.org/developer/sahara/userdoc/features.html#neutron-and-nova-network-support
and it says Nova Network. Is that right?

[openstack-dev] Contribution work flow

[Sharan Kumar M]

Hi,

I am about to submit my first patch. I saw the contributions guidelines in
the documentations. Just to make it clear, is it that I issue a pull
request in GitHub, which automatically pushes my patch to gerrit? Also, I
found something called change-Id in the commit message. Is it the hash code
for the git commit? If yes, should we prefix a 'I' in the beginning of hash
code?

Thanks,

[openstack-dev] [Sahara] Working on DOC bug

[Sharan Kumar M]

Hi,

After digging a little into OpenStack basics, setting up devstack and
starting with sahara, I browsed the list of bugs on Launchpad. I saw a low
hanging fruit bug, which is a wishlist as well.
https://bugs.launchpad.net/sahara/+bug/1350063

But before I start, I would like to get some advice on how to get started
with it, any resources for this bug etc. Just to let you all know, I am new
to OpenStack and this would probably be the first patch I submit.

Thanks,
Sharan Kumar M

[openstack-dev] Error creating instances in DevStack

[Sharan Kumar M]

Hi,

I am trying to setup my own OpenStack cloud for development. I installed
DevStack on a VM and the installation is fine. I am able to log in via
Horizon. I followed these steps to create an instance via Horizon.
http://isurues.wordpress.com/tag/devstack/. However, when I launch an
instance, I get the following error.

Failed to launch instance nova: Please try again later [Error: No valid
host was found. ]

I checked if the libvirt_type=qemu in nova.conf. Also the package
nova-compute-qemu is installed. I am using Ubuntu 14.04.

Can someone identify why this problem occurs and how to solve it? What are
the possible causes for this problem?

Thanks,
Sharan Kumar M
