Hardware problem: rsync.opensuse.org down

January 11th, 2016 by

rsync-logoWhat a start in the new year: the server running rsync.opensuse.org died with two broken hard disks at 2016-01-10.

As the hardware is located in the data center of our sponsor IP Exchange, we apologize for the delay it will take to fix the problem: we need not only the correct replacement hard drives, but also a field worker at the location who has the appropriate permissions and skills.

During the downtime (and maybe also a good tip afterward), please check on http://mirrors.opensuse.org/ for the closest mirror nearby your location that also offers rsync for you.

What to expect from Btrfs on openSUSE 13.2?

November 12th, 2014 by

As the first major Linux distribution to have Btrfs as the default file system, what can users and developers expect from openSUSE 13.2?

How is the systems capabilities enhanced?

Btrfs has different performance characteristics; it’s a logging-style file system that provides fault tolerance, repair, and easy management features.

The most well known advantage of Btrfs is the rollback capability with the open-source tool Snapper.

“Btrfs is mature,” said George Shi, who helped rollbacks become a reality for openSUSE users. “It works with Snapper to implement snapshot and rollback, the killer function of Btrfs. You can pick any date you saved to rollback your full system.”

rsync.opensuse.org unreliable

June 17th, 2012 by

rsync logoOur rsync server ‘rsync.opensuse.org’ is currently unreliable and crashes very often. Reason might be hardware related: we are still searching for the real issue.

Please choose one of the available rsync mirrors listed on http://mirrors.opensuse.org/ instead: those get their files from our staging server and are normally as up to date as rsync.opensuse.org.

Sorry for the inconvenience caused. We will update this post once we fixed the problem.

openSUSE’s MirrorBrain and a New Lizard in China

August 29th, 2008 by

Do you know openSUSE’s MirrorBrain?  I have been working on it for over a year now. It is a mirror framework which is open source and can be used by anyone.

The other day, I received the following sentiment:

I fully appreciate your work. In my view openSUSE has the best managed download mirroring in place! Only few come close!

It was the admin of one our our mirrors who wrote this. A large one, which does mirror more than 100 projects other than openSUSE.

It is nice to see (and important for us) if mirror admins are happy. Mirrors are crucial to get openSUSE out to you. Without mirrors, we are nothing. Our little download server could not serve you on its own. download.opensuse.org receives 15.000.000 to 40.000.000 requests on a normal day. But together with the friendly organizations that mirror us, we have been serving at least 25-30 gigabytes per second (!) to you at peak times.

A lot happens behind the scene to make sure that openSUSE is continuously and easily available. If you never actually notice anything about it, then it only means we are doing well!

For instance, I am always searching new mirrors. One of the biggest recent achievements was that Coly Li, our Chinese friend, installed the first “real openSUSE” mirror in China: http://www.lizardsource.cn/. In China mainland, there are already several sites that mirror opensuse, now lizardsource.cn is the first opensuse specific mirror and the largest openSUSE mirror so far.

When talking to Coly about the situation in China, he provided the following insight:
(explanatory comment: GFW refers to the censorship system, nicknamed Great Firewall of China)

Our motivation is:

1) international internet connection is slow from China mainland, no matter GFW exists
2) Most of universities and institutes use CERNET, they can not connect to international internet directly.
3) South China and North China use different public internet networks, inter-connections is very slow.

There are several opensuse mirrors in China already, but they are 1) limited to a small group of people, or 2) slow for non-charge users, or 3) out of maintenance.

lizardsource.cn can be accessed from both universities, institutes, south China, north China. The download speed within China mainland is much faster, people from universities observed 200KBytes persec. That’s the advantage and importance of lizardsource.cn.

Some other mirrors I could acquire last month (good ones) were in Nicaragua, South Africa, Indonesia, Poland, Latvia and other countries.

On the more invisible side, last week I have extended the mirror framework so that it can run in multiple instances on one machine; this may open up some interesting applications later, because we could run a separate redirector for separate file trees, with a different set of mirrors.

Gerard Fàrras, one of our GSoC students, is working on incorporation of a metalink client into YaST/zypper. Once that is implemented, it will make our package installer much much more robust against all sorts of network issues. A working prototype exists!

Currently, I am researching on a somewhat complicated idea to achieve a more fine-grained mirror selection scheme. More on that later maybe.

The outdated wiki pages that list mirrors need to be replaced by real-time lists generated from the mirror database. I don’t know when I/we get around to do this. If anyone would like to hack on a web frontend for the mirror database (I am picturing a TurboGears app that integrates with the existing Python mirror toolbox), contribution would be most welcome; let me know if you are interested!

See http://mirrorbrain.org for more info about the framework we use. Info for site operators interested in mirroring us is to be found here.
