2 node vs 3+ node clusters

A comment on my post about the failure probability of clusters suggested that a six node cluster that has one node fail should become a five node cluster.

The problem with this is what to do when nodes recover from a failure. For example if a six node cluster had a node fail and became […]

failure probability and clusters

When running a high-availability cluster of two nodes it will generally be configured such that if one node fails then the other runs. Some common operation (such as accessing a shared storage device or pinging a router) will be used by the surviving node to determine that the other node is dead and that it’s […]

We are having a release party on Saturday the 14th of April. We meet at mid-day under the clocks at Flinders Street Station and then go somewhere convenient and not too expensive for lunch.

All welcome.

presentations about SE Linux

I have just read the Presentation Zen blog post about PowerPoint.

Xen and SE Linux – EWeek review of RHEL5

It’s quite a positive review which can be summarised as “good support for Xen as service (not an appliance), better value than previous versions with the licenses for multiple guests included, and SE Linux briefly got in the way but the Troubleshooting tool fixed it […]

what is a BOF?

BOF stands for Birds Of a Feather, it’s an informal session run at a conference usually without any formal approval by the people who run the conference.

Often conferences have a white-board, wiki, or other place where conference delegates can leave notes for any reason. It is used for many purposes including arranging BOFs. To […]

A Strange Interpretation of the US Constitution About Copyright

In a blog on infoworld the following strange statement appeared:

The US Constitution is clear that the reason for copyright/patent/etc. is to benefit creators of property, not users of property. I appreciate the reason: give creators a reasonable return on their investment. Actually the US constitution seems to clearly say the opposite. Here is a […]

BSD vs GPL licences

James Dumay writes about Theo’s latest flame-war.

One interesting part of the debate was Theo’s response to this comment: > We can dual license our code though and that is an > acceptable license for Linux, the kernel. Theo: We? Sure, you can. But Reyk will not dual license his code, and most of the […]

Sam Hocevar ran for DPL on a platform based on some significant new changes. It will be interesting to see what happens over the next year.

The release of Etch is an exciting milestone in Debian development. Among other things it […]
