A CentOS docker image

I’ve just pushed out to testing, a docker image for CentOS-6/x86_64 ( details are here: http://lists.centos.org/pipermail/centos-devel/2014-April/010070.html; This image is built on the work done Chris St. Pierre and hosted at https://github.com/CentOS/sig-cloud-instance-build.

We are calling upon new and existing docker.io users to test this image and provide feedback; with the intention that we can move this towards a baseline gold CentOS Docker image in the near future.

The ARM plan for CentOS

ARM is an interesting platform for many reasons and many people around the CentOS ecosystem have often spoken about a native, maintained and in-sync CentOS ARM build might be. But a couple of major drawbacks have kept us ( and others ) from being able to deliver on this. The most important ones are that the CentOS-6 codebase is now old enough that a lot of the really cool things in recent ARM development were not included in there ( gcc ver, kernel ver, glibc etc ), and backporting large chunks of this code is truely beyond the scope of what we can do and have done in the past within the realm of the Core SIG. Also, making that level of change automatically forks the CentOS codebase, creating potential package orphans. This problem goes away with the CentOS-7 codebase, just looking at the RHEL7beta1 codebase, its clear that we should be able to build a reasonable ARM story around it.

Another challenge has been finding and working with reasonable hardware that we might be able to target CentOS ARM on. To that end, David Power and the guys at Boston UK have provided us a couple of instances in their Viridis, ARM as a Service Cloud to start the process off with. These are ARM32 HighBank nodes, that are able to run builds and tests at reasonable speeds ( the test gcc build that Johnny ran last week took ~ 8 hrs to finish ).

What we are then looking to do from here is bootstrap the rhel7beta codebase against fedora19 ( which runs really well on these nodes ) for an ARM32 build. Once we have that in place, we are going to try and see if we can get to a self-hosting state and prepare ourselves for the EL7 GA announcement. The aim being to try and build + deliver an ARM32 distro in sync with the mainline x86_64 distro.

This is going to be a fair bit of work, and towards that we are going to need people to come help with the builds, with the testing and we are also going to need more vendors to offer us hardware that we can use to build and test against. We have a mailing list on at http://lists.centos.org/mailman/listinfo/arm-dev called Arm-Dev, we will try and focus all the interest in ARM onto that list, so come and join the effort.

The present state is that Johnny is stress testing the nodes, doing some test builds, writing up the mock configs. Once this is done, we will get the reimzul builders running on there, and start accepting build requests, build patches and start pushing build logs etc.

One challenge that still remains is that the big Red Hat TM and branding hunt into the rhel7beta code has not happened – and this is blocking the i686 as well as the x86_64 rpms from being publicly visible. We do have a small plan for that, and it involves kicking off a community exercise in the second week to April and to build both a whitelist and a blacklist of code, rpms and to write some automated patching resources to handle the whitelisted content. Details about that in another post soon.

In the mean time, welcome to the ARM32 build effort on CentOS-7beta ( and ongoing ). We’ll see you on the Arm-Dev mailing list.

Downtime ahead for all centos.in services

hi,

While the internal network in the centos.in cluster ( which is part of lon0.karan.org ) has been on gigabit for years, the uplink from there has been on 100mbps. Today I’m hoping to go into the DC and upgrade that to a gigabit as well. While I am there, I also want to consolidate some of the infra. So there is going to be some downtime on services hosted there. Includes seven.centos.org, boot.centos.org, centbot, and some of our build services. Downtime is expected to start around 11:30 UTC and everything should be back online by 18:00 UTC today, Sun Mar 23rd.

Concerns, help, comments and all other kinds of feedback welcome in #centos-devel on irc.freenode.net

Shout out to the guys at Coreix ( http://coreix.net/ ) who sponsor this rack. If you need hosting in the London area, include them in your short-list.

CentOS Mirrors “Spring Clean-up operation”

Just to let you know that I have verified some mirrors last week and sent several mails to the contact info we had for those mirrors (unreachable/far behind).
I've received feedback from some people still willing to be listed as third-party mirror and so they fixed the issue they had (thank you !)

Some other people replied with a "sorry, we can't host a mirror anymore" answer . (Thanks for having replied my email and thank you for having been part of the successful "centos mirror party" !).

For the "unanswered" ones, I've decided that it was time to launch a "Spring clean-up operation" in the mirrors DB/Network.
I've removed them from the DB, meaning that the crawler process we use to detect bad/unreachable mirrors will not even try anymore to verify them.
We actually have more than 500 external (third-party) mirrors serving CentOS to the whole world, without counting the 50+ (managed by CentOS) servers used to feed those external mirrors, and sometimes serving content too for countries less covered.

Thanks a lot for your collaboration and support ! We *love* you :-)

CentOS Dojo Santa Clara – 31 March before MySQL Conf

On the eve of the Percona Live:  MySQL Conference and Expo (Monday 31 March 2014) I get to help run my first CentOS Dojo at the Santa Clara Convention Center. For this event, I’ll MC and give a talk about the newness in the CentOS Project. The lineup so far is pretty set and quite stellar:

  • Jeremy Carroll — Systems Automation and Metrics at Pinterest:  ”At Pinterest metrics instrumentation and presentation has been an increasingly vital as our systems scale …”
  • Monty Widenius — Notes on MariaDB 10:  ”MariaDB is coming along in great strides, and is now included by default in the EL7 Beta cycle …”
  • Peter Zaitsev — Running MySQL on CentOS Linux:  ”Linux is by far the most common platform to run MySQL, and there is a lot of accumulated knowledge about which way is best to run MySQL …”
  • Jordan Sissel — Happy Tools:  ”Happy tools! This talk will introduce three different operations-friendly tools to help make you happier …”
  • Joe Miller – Two Years in Your Future:  ”Systemd is the new kid on the block, everyone is talking about it, everyone is thinking about it, everyone is planning for it …”
  • Joe Brockmeier — Software Collections on CentOS:  ”The power to build, install and use multiple versions of software on the same system, without affecting system-wide installed packages. Welcome to software collections …”
  • Karsten Wade — The New CentOS Project:  ”A new Board member’s perspective on where the CentOS project is today and the road ahead …”

Massive thanks to Joe Brockmeier and Karanbir Singh (of the OSAS and OSAS/CentOS Engineering teams) and Kortney Runyan and the event crew at Percona. If you want to attend, hop on it — space is limited. :) It’s a no-cost event and comes with the bonus of a no-cost expo and keynote pass for Percona Live. Oh, did I mention we’ll serve you some lunch and generally treat you right?

If you are attending the main conference, visit us as the CentOS Project booth in the DotOrg Pavilion — or contact me if you are interested in staffing the booth.

OpenStack Icehouse on CentOS-6

Openstack Icehouse, the next major version release in Openstack is coming soon ( target April 2014 ); and the RDO folks are hosting a couple of test days on the 19th and 20th of March so everyone can trial the code, the packaging, the update process and delivery mechanisms around this new release. If you have used openstack in the past, but not used the RDO distribution for it, these tests days can be a great intro towards that as well.

Details on the test days can be found on the RDO site at : http://openstack.redhat.com/RDO_test_day_Icehouse_milestone_3, as a prep I highly recommend starting with a clean CentOS-6.5 minimal install and running through the RDO quick start guide.

Update: The test schedule got postponed to March 25th and 26th.

Createrepo and Parallel Delta RPMs on CentOS-6

Anyone who is using Delta RPMs (AKA - the yum-presto plugin) on CentOS-6 or Fedora knows how much of a PITA it is to generate the drpms.  It takes forever to generate.

Ian Mcleod has posted some new functionality on the Yum Developers mailing list that addresses this issue.

Here is the git repo that contains the new code.

I have created an RPM and SRPM for EL6 that use the tarball from the git repo and add the following functionality:

--delta-workers - The number of worker processes to use for delta
related tasks

--max-concurrent-delta-rpm-size - The maximum total size of uncompressed
rpm payloads that are actively being processed by makedeltarpm at any
given time.

You can get copies of the RPMS from my people.centos.org location for testing. 

The only things that I found with the rpm is:

1.  You will need to also install pyliblzma package from epel to use it.

2.  You should use the same (or lower) number of --delta-workers as compared to --workers 

3.  As discussed in the Yum Developers thread above, you want to make sure to assign a value to --max-concurrent-delta-rpm-size .  The number to assign is bytes ... so 16GB (if you have a 64GB ram machine, and the recommended amount is about 25%) then it would be 16 x 1024 x 1024 x 1024 = 17179869184 (as an example).  That machine also has 24 CPU cores ... so I used 24 for --workers and --delta-workers.

MATE on the Desktop

A number of people seem to not like the idea of gnome3 on the desktop for EL7, instead looking for the familiar gnome2 feel. I’ve taken a run at building MATE on the el7 beta and it looks pretty good overall. Over the next few days I’d like to sit down with some of the interested parties to discuss the best way to move forward with this as perhaps the beginning of the “Desktop SIG”.

SCALE 12x – CentOS and Infrastructure.Next

We’re very excited over here to be attending the twelfth annual Southern California Linux Expo, aka SCALE 12x, on 21 to 23 February in likely-to-be-sunny Los Angeles.

On Friday, I’m going to hang out near the stage and nod cleverly as Jim Perrin tells us about “Growing CentOS as a Platform for Infrastructure Development“. You can register for Infrastructure.Next (it’s no-cost!) here. It’s a full day devoted to learning about how real people are solving real problems with open source. I’ll have to visit my friends at the Fedora Activity Day. Then I’ll do the brisk-for-LA dinner so I can get back for Lawrence Lessig’s keynote, “Only You Can Get This, So Where Are You?” at 9 pm.

Saturday is dedicated to all the fun the expo has to offer, plus the evening activities. I’ll be hanging out at the Fedora, CentOS, and Red Hat booths. I’ll definitely carve time for m’man Jason Hibbets’ “Open Source ALL The Cities” – a topic near to my heart, one I’ve acted on, but barely to the extent Jason has, so I’m looking forward to learning more from him (and seeing a friend speak, natch.) Closing Saturday, two other friends-also-faves are Ruth Suehle (“Raspberry Pi Hacks“) and Rikki Endsley (“You know, for kids! 7 tips for improving tech education in our schools“), at 6 pm opposite each other (curse the schedule overlords!!!), I may have to favor Rikki as I had the fortune to catch Ruth in Scotland talking on the same topic a few months ago … which is another story. And look! I have another colleague, Rich Bowen (“Demystifying mod_rewrite“) at the same time (a skill I sorely need to demystify), and I note Dawn Foster is talking as well … So much goodness!

Sunday kicks off for me with Leslie Hawthorn at 10 am with “Why Checking Your Privilege is Good For *You*“. Leslie is another friend-and-great-speaker, but I’ll note that she’s particularly interesting to listen to and I think more so on this topic. I’m very much looking forward to this, especially as the newbie feminist that I am. Then Thomas Cameron is speaking on “Next Generation High Availability Linux Clustering” at 11:30, which I hope to be able to catch some of (and heckle.). I’ll be preparing for the “CentOS Project Q&A Forum” that I’m leading with Jim Perrin and Johnny Hughes at 1:30, where I’m looking forward to some reverse-heckling from Thomas. Perusing the schedule, I found the quite intriguing, “Hacking the Kernel, Hacking Myself” talk by Kelley Nielsen at 4:30. I’ve quite interested to hear her story around the domains of kernel development, personal development, the Outreach Program for Women, and her story overall.

GSoC at CentOS office hours

I love how KB started CentOS Project online office hours right after our joint announcement about the new relationship between Red Hat and CentOS. I don’t think this sort of thing was happening before, but it’s now a regular part of exposing the inter-workings of the new CentOS Governing Board.

This Monday 10 February at 16:00 UTC (yes, that’s 8 am in California for me) we’ll be talking about CentOS and the Google Summer of Code. You can watch via the YouTube channel or http://www.centos.org/media, and participate in IRC on #centos-devel on Freenode,  Here’s my quick agenda for the hour:

  • Quick summary of what Google Summer of Code (GSoC) is.
  • Overview of what is possible to do with GSoC for CentOS.
  • What we have so far.
  • What we need to work on now (this week), next (following few weeks), and for the summer (full program length.)

See you there!

Kernel-ml, NVIDIA Drivers, and the 3.13.x kernel

ELRepo has a Main Line kernel section to allow using the latest kernel with CentOS-6.  I use this kernel on my laptops and workstations as it usually means better hardware detection and battery life, etc.

If you have the need to use the proprietary NVIDIA drivers with this kernel, as I do on one of my laptops, then you would need to install the latest NVIDIA drivers for each kernel.  No one (that I know of at least) maintains an RPM based module for the kernel-ml series, so downloading the latest version of the drivers from NVIDIA's site is how I handle this situation.

Sometimes with a new kernel tree is begun, in this case the 3.13.x kernel tree, the NVIDIA drivers as posted with not work.  This is the current situation with the 3.13.2 kernel (as installed via ELRepo on CentOS 6.5 ) when using the latest NVIDIA drivers (currently version 338.31).

On the web, I found a good blog entry on how to generally fix the issue, so I thought I would go over how to make it work on CentOS-6.

  • Enable the ELRepo repository (if required) using their instructions here.
  • Install the ELRepo kernel-ml via their instructions here.
  • Download the latest NVIDIA Drivers from the NVIDIA site.
  • Change the permissions on the downloaded binary file so it can be executed:
chmod 755 NVIDIA-Linux-x86_64-331.38.run
  • Extract the NVIDIA drivers with this command in a terminal:
./NVIDIA-Linux-x86_64-331.38.run -x

  • Download the combined (2nd) patch from the above blog and save it (right click, save link as) into the NVIDIA-Linux-x86_64-331.38 directory created when extracting the driver above.
  • Apply the patch with this command:
patch -p1 < 02_nvidia_3.13.patch

  • Reboot into the new kernel (will get console mode, login as root) ... then go to the  NVIDIA-Linux-x86_64-331.38 that contains the patched code.
  • Install the patched driver with this command:
./nvidia-installer
The install should now complete in the normal way, and you should be able to boot into the NVIDIA driver on the 3.13.x kernel-ml series from ELRepo on CentOS-6.5

Traffic to the new CentOS website

When we were redesigning the CentOS website, we decided to use basic Google Analytics to provide the stats and metrics surrounding website traffic.

CentOS Seven blog

Running 7 as a desktop

In the interest of preparing for the el7 release, I’ve decided to attempt to migrate my primary machine to the el7 beta. For the most part this seems like it will be a reasonably easy transition, though admittedly I play with fedora frequently so the gnome2 to gnome3 transition is something I’ve already handled. If you find that you absolutely must have the wobbly windows, and desktop cube effects which are available in el6 then you’re in luck. All you have to do is transition from gnome to KDE, where these features are alive and well.

Apart from the gnome adjustment, there are a few things that I use regularly which just aren’t in the beta. Nearly all of these packages can rebuild cleanly for el7, using mock and the f19 srpms. For me these packages were transmission, pidgin-otr, thunderbird and its assorted plugins. The ‘fedora’ chrome packages google offers work flawlessly as well.

I was even able to get skype working in the el7 beta reasonably easily. The fact that skype is 32bit only complicated things slightly, as I had to borrow  qt-mobility.i686 and qtwebkit.i686 from fedora to deal with the install dependencies. Once the i686 sig build of el7 is ready for additional packages, this rpm abuse shouldn’t be needed any longer.

I’ve been asked already about posting the rpms that I’ve built for the 7 beta, but I don’t want to do this. I don’t have an interest in maintaining them long-term, and I’m certain they’ll end up in epel or another repository  shortly.

First community contribution

And there we have it, the first community contribution via git.centos.org is now live.

Andreas Thienemann’s offered to test and do some work of the work around the i686 CentOS-7 builds; and has gone through to propose mock configs that allow the i686 tree to be bootstrapped. I’ve just merged his pull request, and pushed it to the builders. The entire distro churn for i686 is now running, with details at seven.centos.org and you can see the build reports published in realtime at http://lists.centos.org/pipermail/centos-build-reports/2014-January/thread.html

This should allow everyone to quantify the scope of work we might be looking at, if as a community, we decide to maintain a i686 tree + installer for CentOS-7.

RHEL7 beta disk partitioning changes

With previous el5 and el6 installs, I would clear the disks, and accept the default lvm layout, though I would adjust the sizes a bit. Ordinarily when I adjusted the sizes, I would leave myself additional free space within the volume group so that I could grow later as needed. Upon installing the rhel7 beta, I discovered this is no longer how disk allocation works. After you select your disk(s)

While I've bounced around to various desktop environments, I have found that I always end up coming back to gnome. That is, until now.
