One of the frequently asked questions regarding ZFS. Is it possible to resize a RAIDZ, RAIDZ2 or MIRRORED ZPOOL?
The answer is a littlebit complicated…
If you want to change the ‘geometry’ of the ZPOOL (for example: change from a mirrored pool to a raidz, or simply add a disk to a raidz, or change from raidz to raidz2) then the answer is no.
But it is possible to change the disks of a pool with bigger ones and use the space.
Two tools which have become the norm in Linux- and Unix-based environments are SSH for secure communications, and sudo for performing administrative tasks. These are independent programs with substantially different purposes, but they are often used in conjunction. In this talk, I describe a flaw in their interaction, and then present our solution called public-key sudo.
Public-key sudo is an extension to the sudo authentication mechanism which allows for public key authentication using the SSH public key framework. I describe our implementation of a generic SSH authentication module and the sudo modifications required to use this module.
Bordeaux is an addon to the Wine project and uses Dan Kegel’s Winetricks script as the backend processor. Unlike Wine which is free, a Bordeaux license costs $20.00.
Work has now started to make Bordeaux work on FreeBSD 7.0 as well (already working on Linux).
Over the last couple day’s I have been working on the Bordeaux for FreeBSD 7 port. We now have everything compiling and running but a lot more testing needs to be done before it’s ready for a final release. Internet Explorer, Steam and Office 2003 are the only applications I’ve gotten around to testing thus far. The good news is everything that I have tested works fairly well on FreeBSD.
If you’re a FreeBSD user and need to run any of the software that we currently support on the Linux client you might be interested in helping beta test this build and future builds up to the final stable release. At this time we can’t give out beta builds, but what we can do is if you purchase a license from the store for a Linux build then send a mail to support. This email is provided once you purchase a licence, and ask for a FreeBSD build I can send it to you.
BSDTalk has a 11 minutes interview with Isaac Levy and Steven Kreuzer. Subject of the interview are the preparations for the upcoming New York City BSD Conference (NYCBSDCon) 2008 (11-12 October 2008, New York). More information on the conference can be found at http://www.nycbsdcon.org/
This conference is listed on my public FreeBSD Events Calendar. Check it out for any BSD related events in your area.

The FreeBSD Developers Summit (15-18 August) has now kicked off in Cambridge (UK). Subject of discussions, amongst others, are operating system virtualisation, access control and the FreeBSD 8.0 release.
Our developer summit here in Cambridge started off rather well today. Robert decided that a brisk half hour walk from King’s to the computer lab was a good start of the day. I happen to agree.
Will keep you updated with any interesting stuff i find out, especially about FreeBSD 8.
For a general idea what sort of things get discussed at Dev Summits have a look at Bjoern A. Zeeb account of the BSDCan 2008 Developers Summit (with pictures).

Just to remind anybody interested in FreeBSD development, the FreeBSD Foundation is
soliciting the submission of proposals for work relating to any of the major subsystems or infrastructure within the FreeBSD operating system. A budget of $80,000 was allocated for 2008 to fund multiple development projects. Proposals will be evaluated based on desirability, technical merit and cost-effectiveness.
If you want to help improve FreeBSD and would like to receive funding to do so, be quick: the deadline is 15 August 2008.
