[Openstack] [all]Naming the T release of OpenStack -- Poll open

2018-10-29 Thread Tony Breeds
Hi folks,

It is time again to cast your vote for the naming of the T Release.
As with last time we'll use a public polling option over per user private URLs
for voting.  This means, everybody should proceed to use the following URL to
cast their vote:

  
https://civs.cs.cornell.edu/cgi-bin/vote.pl?id=E_aac97f1cbb6c61df&akey=b9e448b340787f0e

We've selected a public poll to ensure that the whole community, not just gerrit
change owners get a vote.  Also the size of our community has grown such that we
can overwhelm CIVS if using private urls.  A public can mean that users
behind NAT, proxy servers or firewalls may receive an message saying
that your vote has already been lodged, if this happens please try
another IP.

Because this is a public poll, results will currently be only viewable by myself
until the poll closes. Once closed, I'll post the URL making the results
viewable to everybody. This was done to avoid everybody seeing the results while
the public poll is running.

The poll will officially end on 2018-11-08 00:00:00+00:00[1], and results will 
be
posted shortly after.

[1] https://governance.openstack.org/tc/reference/release-naming.html
---

According to the Release Naming Process, this poll is to determine the
community preferences for the name of the T release of OpenStack. It is
possible that the top choice is not viable for legal reasons, so the second or
later community preference could wind up being the name.

Release Name Criteria
-

Each release name must start with the letter of the ISO basic Latin alphabet
following the initial letter of the previous release, starting with the
initial release of "Austin". After "Z", the next name should start with
"A" again.

The name must be composed only of the 26 characters of the ISO basic Latin
alphabet. Names which can be transliterated into this character set are also
acceptable.

The name must refer to the physical or human geography of the region
encompassing the location of the OpenStack design summit for the
corresponding release. The exact boundaries of the geographic region under
consideration must be declared before the opening of nominations, as part of
the initiation of the selection process.

The name must be a single word with a maximum of 10 characters. Words that
describe the feature should not be included, so "Foo City" or "Foo Peak"
would both be eligible as "Foo".

Names which do not meet these criteria but otherwise sound really cool
should be added to a separate section of the wiki page and the TC may make
an exception for one or more of them to be considered in the Condorcet poll.
The naming official is responsible for presenting the list of exceptional
names for consideration to the TC before the poll opens.

Exact Geographic Region
---

The Geographic Region from where names for the S release will come is Colorado

Proposed Names
--

* Tarryall
* Teakettle
* Teller
* Telluride
* Thomas : the Tank Engine
* Thornton
* Tiger
* Tincup
* Timnath
* Timber
* Tiny Town
* Torreys
* Trail
* Trinidad
* Treasure
* Troublesome
* Trussville
* Turret
* Tyrone

Proposed Names that do not meet the criteria (accepted by the TC)
-

* Train๐Ÿš‚ : Many Attendees of the first Denver PTG have a story to tell about 
the trains near the PTG hotel.  We could celebrate those stories with this name

Yours Tony.

Re: [Openstack] [Swift] PUT Object performance problem

2018-10-29 Thread SeongSoo Cho
Hi clay

I just using the command like `swift-ring-builder object.builder
set_weight  d234 2220`.
Then execute `swift-ring-builder object.builder rebalance` and push the
rings all object node.

Here is more detail information.
I/O scheduler : deadline
OS : CentOS 7.4
Kernel version : 3.10.0-693.11.1.el7.x86_64

I will try decrease the node_timeout from 3 to 1.  (Do you have any
recommend value?)

Re: [Openstack] setup private cloud environment

2018-10-29 Thread Bernd Bausch
Recommendation: Use the installation tutorials on docs.openstack.org.
They start with a two-node cloud, but depending on how you want to use
your three boxes, it should be no problem extending the setup to three.
This will be a very manual setup, time-consuming but with a great
learning effect.

There are several automatic or semi-automatic deployment tools that you
should evaluate: Packstack (very easy), Kolla and Kolla-Ansible,
OpenStack-Ansible. The latter two may require more power than a typical
PC delivers. Their advantage: They can set up highly available clouds.

Devstack is another solution. I don't know how hard it is to extend a
single-node setup to three nodes. Since Devstack's purpose is
development and testing, it doesn't really focus on robustness.

Triple-O is probably not for you, as it requires servers with IPMI
interface. But there are ways to virtualize IPMI, so that you should
evaluate this method as well.

I am sure there are other methods. One thing to consider: Setting up an
OpenStack cloud is not like installing a typical Linux box. There are
many (many!) moving parts and many (many!) opportunities to make
mistakes. Keep that in mind and don't give up.

[Openstack] DHCP not accessible on new compute node.

2018-10-29 Thread Torin Woltjer
Recently installed a new compute node, but noticed none of the instances that I 
put on it will successfully receive network addresses from DHCP. This seems to 
work on all other compute nodes however. When listening for DHCP requests on 
the vxlan of the compute node, I notice that while I can see the DHCP requests 
on the new compute node, I do not see them anywhere else. If I manually assign 
an address to the interface on the instance I am able to ping in and out. 
Running dhclient -v on an instance on a working compute node successfully gets 
a DHCP response, on the new compute node there is no response, I also 
discovered that the instance on the new compute node cannot ping the DHCP ports 
at 172.16.1.2 & 172.16.1.3 yet can ping the gateway at 172.16.1.1.

The setup is neutron-linuxbridge on Openstack Queens.

list. The new list is open for subscriptions[0] now, but is not yet
accepting posts until Monday November 19 and it's strongly
recommended to subscribe before that date so as not to miss any
messages posted there. The old lists will be configured to no longer
accept posts starting on Monday December 3, but in the interim posts
to the old lists will also get copied to the new list so it's safe
to unsubscribe from them any time after the 19th and not miss any
messages. See my previous notice[1] for details.

Re: [Openstack] [Swift] PUT Object performance problem

2018-10-29 Thread Clay Gerrard
Obviously a re-balance will cost some IO, but it's normally perceptible to
the client unless you were already on a razor thin line.

Two config options seem obvious to think about experimenting with:

You could decrease the node_timeout and let the proxy try to write more to
handoffs
You could try to use some of the ionice options (or other tuning options)
to make the replicators hammer the disks a little less

It might having something to do with how you're organizing your ring weight
changes - could you describe how you're managing rings?
Could also be a io scheduling issue - are you using noop/deadline or cfq?
What kernel version?

[Openstack] [Swift] PUT Object performance problem

2018-10-29 Thread SeongSoo Cho
Hello, All

I have a terrible problem with object server.
Here is the case.
1. User upload an object to proxy-server
2. Proxy server try to connect with object-server
3. If one of object-server is slow to respond, proxy-server is waiting for
response.
  3.1 While waiting for response, proxy-server can't do anything
4. So, The response of client request will be delayed.

In my opinion, this code seems to be a problem
(
https://github.com/openstack/swift/blob/stable/rocky/swift/proxy/controllers/obj.py#L1734
)

```
with ResponseTimeout(node_timeout):
resp = conn.getexpect()
```

If node_timeout's value is 3 and object-server respond after 2 seconds,
proxy-server wait 2 seconds.

Because proxy-server wait for the above response, the execution of the
following code is delayed.
(
https://github.com/openstack/swift/blob/stable/rocky/swift/proxy/controllers/obj.py#L627
)

```
for node in nodes:
try:
putter = self._make_putter(node, part, req, headers)
self.app.set_node_timing(node, putter.connect_duration)
return putter
```

This problem occurs when i do a ring rebalance.
When object-replicator delete a partition directory that are no longer
mine, the disk becomes very busy (Because of xfsaild daemon)
Because the disk are busy, object-server can't create diskfile during PUT
operation.

Is there anyone who is having problems like me?
How can I solve this problem?

I need everyone's help.
Thanks.

Best Regards
SeongSoo Cho
