Re: [Openstack] Admin guide

[Nasir Mahmood]

Venkatesh,


There is OS architecture guide, giving you the fully detailed information
on how and why OS is using a particular piece of software.
 then there are admin and Operations guides for maintaining and running an
OS setup, including HA and other similar stuff. try reading them or buy
some online books from PACKT or Oreilly's , they are pretty much
explanatory in terms of understanding things. One of the books you might be
interested in "Learning the Openstack networking ( neutron )" particularly
for networking part,  OpenStack Essentials for understanding the OS in
generic.


Hope this helps.

Re: [Openstack] help openvswitch network configuration problems

[Akash Gunjal]

Hi,

In your screen shot I see the IP is still on eth2 port. When you add the
eth2 to br-ex OVS bridge, you need to move the IP of eth2 to br-ex for the
connectivity to work.

Akash

Subject:[Openstack] help openvswitch network configuration problems




 Hi Everyone,
 I am now configuring openvswitch for openstack cloud. I have a network
 node in the cloud and it has 3 network cards. When I did as the Openstack
 Install Guidance said to add port eth2, which is the interface that
 connects to the internet in dhcp mode, to the external bridge br-ex, the
 whole network node become disconnected from the internet.
 Here is the network interface file:

 # interfaces(5) file used by ifup(8) and ifdown(8)
 auto lo
 iface lo inet loopback

 # management interface
 auto eth0
 iface eth0 inet static
 address 10.0.0.21
 netmask 255.255.255.0
 #gateway 10.0.0.1

 # tunnels interface
 auto eth1
 iface eth1 inet static
 address 10.0.1.21
 netmask 255.255.255.0

 # external network interface
 auto eth2
 iface eth2 inet dhcp
 up ip link set dev $IFACE up
 down ip link set dev $IFACE down

 After add eth2 to br-ex, ifconfig presents the following configuration:



 Note: A lot of drop in bridge.

 Openvswitch configuration:

 If I remove eth2 from br-ex, then everything goes well.
 By the way I use NAT to connect all other node in the cloud to the
 internet, but even if I cancel NAT noting changes. And also I have enabled
 ipv4 forwarding.
 Any suggestion is warmly welcomed! Thank you very much!!

 hjh!

Funny - the Ceph guys are discussing this very issue (in particular with
Intel SSD, but the thread is generally informative...and quite long):

Re: [Openstack] To remove particular project

[Steve Martinelli]

++ removing the endpoint and service from Keystone was my first thought as
well.

You could probably remove the package without the dependencies using 'rpm
--nodeps' but I'd just stick to removing the service from the catalog via
Keystone.

Thanks,

[Openstack] Call for mentors Outreachy Dec-March 2016

[Victoria Martínez de la Cruz]

Hi everyone,

OpenStack will join next round of the Outreachy internships and we need you
help: we are looking for full-time contributors willing to share some of
their time, knowledge and experience to make our open-source organization
more diverse and have the opportunity to meet new talents.

*What is Outreachy*

Outreachy helps people from groups underrepresented in free and open source
software get involved. Read more in https://www.gnome.org/outreachy/.

OpenStack has been participating in this internships since Jan-Apr 2013,
and we have had really good results: we got more full-time contributors, we
got lots of good quality contributions, interns had the opportunity to give
a great step in their professional careers and also it has been an
enriching experience for everyone involved with the internship. More
information about OpenStack participation in Outreachy can be find in
https://wiki.openstack.org/wiki/Outreachy.

*Applications open next September 22nd, and the deadline for applications
is October 27th. *https://wiki.gnome.org/Outreachy/2015/DecemberMarch

*TLDR*

Contributors interested on mentoring in Outreachy, please feel free to ask
any question and ask for further directions here or in #openstack-opw in
Freenode.

Try to find and propose a task for the next couple of months for your
mentee. The task should be able to be finished on three months. Add this
idea in this wiki https://wiki.openstack.org/wiki/Internship_ideas.

Please join #openstack-opw as well, to welcome applicants and help them
with their setups.

Another way to get in touch is through the internships mailing list,
http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-internships.

*Mentors*

*Time requirements*

Being a mentor shouldn't take a lot of time from your working week. Mentors
from previous rounds organized differently: you can schedule a weekly
meeting to catch up with your mentee latest work, questions and next steps;
some other prefer having a daily short meeting; you choose how to organize
your agenda.

Consider that different mentees will need different guidance, but we aim to
work with proactive and independent people. This qualities are defined
during the application process, so make sure to participate actively in
this so you make sure you get a mentee you can work with.

*Tasks*

Mentors are supposed to act as a channel for mentees with the rest of the
community. You should be able to help them understand the community
workflow (tools, milestones), introduce them to the team you are working
with (so they also have other people to learn from), help them to gain
confidence and participate of the weekly meetings.

You are not supposed to teach them the basics (say, we cannot have people
that cannot program in Python), but you should be able to point them in the
right direction with the tools we use in the community and they should be
able to learn at their own pace.

*Mentees*

*Time requirements*

It is a full-time internship, so mentees are expected to work 40 hours per
week in the assigned project.

*Tasks*

Mentees are supposed to devote their time on learning about the community,
getting familiar with the tools used to contribute to OpenStack,
understanding the basics of the code base of the project they are working
on and finishing the assigned task before the internship ends. They are
also encouraged to help with bug triaging, bug fixing and code reviewing.
All this should be shared in a personal blog mentees have to set up when
they start with their internships.

Thanks all,

Victoria

That advice isn't quite accurate.  It says "Enabling barriers effectively turns 
all writes into Write-Through operations, so the write goes straight to the disk 
platter and you get little performance benefit from the raid card (which hurts a 
lot in terms of lost iops)."


That's actually not necessarily true.  It's complicated (See 
http://marc.info/?l=linux-scsi&m=136674609728515&w=2 for discussion) but from 
what I understand most hardware RAID controller vendors will not actually flush 
their non-volatile cache on a SCSI "SYNCHRONIZE CACHE" command.  They will 
ensure that the data is in the NV cache, and then return to the host.  (Which 
should be quick.)


This gets you the best of both worlds...you get the reliability of filesystem 
barriers enforcing ordering through the OS stack, with the performance benefit 
of not having to flush the data all the way down to the disks.
