DRBD has entered a new phase. After being developed out of tree for 9 years, and after an extended review and streamlining phase since March, Phil submitted DRBD to be merged into 2.6.32 release of the Linux mainline kernel. The submission was accepted by block layer maintainer Jens Axboe, who merged DRBD in September, then deferred to the 2.6.33 merge window, and this morning Linus …

Microsoft has announced that it is to contribute code to the Linux kernel development effort under the GNU General Public License (GPL) v2. What on earth does it all mean? Here’s our take on the situation. With thanks to Jay Lyman for his contribution to the following:

Q. This is a joke, right?

A. Not at all, although if any announcement is better suited to the image above, we can’t think of one. Microsoft has announced that it is going to contribute code to Linux under the GPLv2.

Q. What code is Microsoft contributing?

A. Microsoft is offering 20,000 lines of its own device drivers to the Linux kernel that will enable Linux to run as a guest …

2.6.29 was released. I don’t usually write about linux kernel releases, thats what Slashdot is for :), but this one introduces write barriers in LVM, as well as ext4 with write barriers enabled by default. If you run this kernel and forget to turn off barrier support at filesystems (like XFS, nobarrier), you will see nasty performance slowdowns (recent post about it). Beware.

Here is my experience trying to run OpenBSD with XenServer 5 Enterprise.

• XenServer console doesn’t function properly as it keeps overlaying text displayed previously or anything you have typed into the console. Makes it very difficult to read and see what you are doing. As well it appears numerpad with numlock on does not work either. The best work around is to SSH into OpenBSD.
• Receiving the following error messages at boot up, “clock: unknown CMOS layout” and “rl0: watchdog timeout”. Yes the NIC is being detected as a Realteak 8139. If I check /var/run/dmesg.boot out of the two error messages I only see the “clock: unknown CMOS layout”. So I would assume the watchdog timeout message occurs after initial boot sequence.

besides a community ?

Some people think that apart from a community and users you also need an infrastructure to support these users.

Murray ignited the discussion by pointing us to the fact that PostgreSQL doesn't have a bugzilla to report an track issues.

Different projects have different approaches. Both the kernel, Drupal and MySQL have build their own infrastructure. Others choose Sourceforge for their projects.

What's your approach ?

DRBD 8.2.3 was released today. Even though just a micro release in terms of version numbering, it comes with a couple of very handy brand new features: on-line device verification, and tunable processor affinity.
