This months meeting will be on ZFS and will include:

• First up are lightning talks. These are 5 minute talks on a single topic. Just come along on the night and talk!

• Well its finally happened, the Oracle Sun Merger, we'll probably want to talk about this for a bit

• Then Alex Sims will look at BTRFS and ZFS, how they differ, how they are the same and what we might need to do to get Linus using ZFS

• P.S. Please bring about $7.50 for Pizza!

During the meeting we'll distribute the 2009 TShirts, CDs, mini-books and "Powered by OpenSolaris" stickers (once you've successfully installed of course :-) ).

There will be an opportunity to bring your OpenSolaris/Solaris issues and questions to the assembled group (without fee:-), particularly installation issues. Installation disks will be available at the meeting (including OpenSolaris 2009.06 and Solaris 10/09) so you might want to bring your laptop and install, eat pizza and learn about OpenSolaris.

The meeting is free and open to the public.

At the Meeting

We had a lively meeting with an attendence of five.

There were lightning talks:

• Richard on the Sun/Oracle announcement videos. A challenge was issued to download some of these to disk.
• Alex highlighted todays blogging by Simon Phipps (Webmink), in particular:
  • Tahoe LAFS. The locally developed distributed backup system, Memorybox was discussed as well.
  • Lent. A suggestion to give up Windows for Lent was rejected as you need to enjoy it in the first place.
• Alex on the changes impacting our usergroup. We're expecting to move venue across the road in a month or two.
• A general discussion on ZFS & NAS. The group was divided into RaidZ and mirroring camps with relevant links from Constantin Gonzalez.
  • Home Server: RAID-GREED and Why Mirroring is Still Best
  • Seven Useful OpenSolaris ZFS Home Server Tips

Alex gave a talk on BTRFS vs ZFS which was quite topical given their respective origins. Relevant links were:

• A short history of btrfs
• zfs vs btrfs comparison
• Slab allocation

Next month we'll be looking at the new 2010.03 OpenSolaris release
