FreeBSD, The Power To Serve And The Privilege To Commit

Filed under: Operating Systems — Tags: — Greg Larkin @ 5:43 pm

Hi readers,

I was recently received an invitation to become a FreeBSD committer in
the ports tree. Over the years, FreeBSD has become an integral part of
the infrastructure, and I have been gradually gaining
experience, adopting ports and submitting problem reports.

I plan to continue working on and expanding my knowledge of this great
operating system
, and if you haven’t given it a try yet or created your
first port, feel free to contact me!

The attached message is my introduction to the other developers. In the
next day or so, I will likely commit my first changes (subject to
approval, natch) to the ports repository, and with any luck the
Intertubes will continue to function correctly!

Subject: Introduction: Greg Larkin
Date: Thu, 17 Jul 2008 16:42:57 -0400
From: Greg Larkin
Organization: The FreeBSD Project

Greetings all,

I want to introduce myself as a new ports committer with xxxxx@ as my
mentor and yyyyy@ as co-mentor. I have been self-employed since 1996
and founded my current company,, LLC, in 2000. After
splitting my time between that company and freelance software
development work for a few years, I finally went full-time with the new
company in 2005.

I learned about FreeBSD from the folks at my former datacenter and liked
its simplicity and consistency after working with numerous Linux
distros. I created my first port (www/webcalendar – 3 years ago now!)
because I wanted to install the software and easily upgrade it with
future versions. Since then, I have created additional ports for
various PHP frameworks, CVS & SVN-related tools and Amazon AWS-related
modules. I’m very interested in the CVS->SVN transition for pcvs, and I
hope to assist in that effort.

I’m privileged to become a committer, and thanks very much to xxxxx,
yyyyy, zzzzz and everyone else for all of the advice and
support that brought me here!

Best regards,

Greg Larkin – The Power To Serve

For Your Convenience – Pre-Formatted Virtual Disk Drives

Filed under: Operating Systems — Tags: , , , — Greg Larkin @ 4:01 pm

Hi everyone,

A while back, I made some blank VMware VMDK images available in various sizes. I am now making some pre-formatted VMDK images available that are even easier to use. Of course, these images are specific to the operating system you’re using, and as long as that’s FreeBSD, you’ll be fine. :)

I can make pretty much any size or operating-system-specific filesystem type, so what else would you like to see?

FreeBSD 7.0 + SCHED_ULE Virtual Machine Available

Filed under: Operating Systems — Tags: , — Greg Larkin @ 2:40 pm

Hi everyone,

I’m diving into some new work with virtual appliances, so I thought I would make a clean FreeBSD 7.0 VM available to you. This one has the following configuration:

  • SCHED_ULE scheduler has been selected instead of SCHED_4BSD
  • Other minor option tweaks in the new kernel config file vs. the GENERIC kernel config. The updated kernel config can be found here
  • Root password is “password”
  • LSI Logic SCSI virtual disks are used instead of IDE so the VM can be deployed to VMware ESX Server
  • /usr/src and /usr/ports filesystems are packaged as separate downloads
  • Two separate base systems are available – one for VMware Server 1.0 and one for VMware Player 1.0. Why these products use a slightly different VMX file format is beyond me!

I plan to use this vanilla VM as the base for future VM downloads, and by breaking /usr/src and /usr/ports into separate downloads, that will keep the overall size down.

All downloads are available from BitTorrent, and please consider seeding the files if you find them useful!

New FreeBSD “Work In Progress” Mailing List

Filed under: Misc — Tags: — Greg Larkin @ 1:51 pm

Hi all,

I just got a message on the FreeBSD-hackers mailing list about a new mailing list where “works in progress” will be detailed: FreeBSD-wip-status.  By subscribing to this mailing list, you will keep up with the cutting edge of FreeBSD development and learn about the many ways that FreeBSD is used out in the world.

Here’s an excerpt from the announcement:

Hello everybody,

Subscribe today!!  Tell all your friends, co-workers and everybody you
know who’s interested in FreeBSD.  Post this on your blog! ;)


if you’ve been around lately you might already know about our effort to
provide periodical status reports about ongoing FreeBSD related WIPs.
The past reports can be found at:

This system has some shortcomings however.  The biggest one is that due to
the collection overhead and the high rate of exciting development under
the FreeBSD umbrella most of the reports are somewhat outdated by the
time they get to “print”.  Other projects never are announced in the
status reports because they happen in-between and fall through the

In order to improve this situation we have created a new mailing list that
should receive status reports from now on.

Getting ElasticDrive to Work Under FreeBSD

Filed under: Operating Systems — Tags: , , — Greg Larkin @ 2:38 pm

Hi everyone,

I recently learned of the ElasticDrive application that implements a disk device backed by Amazon S3 and other kinds of storage services. To determine whether I could easily deploy an infinitely-scalable disk device on my FreeBSD servers, I downloaded ElasticDrive and proceeded to install it on a FreeBSD 7.0 virtual machine.

There are a few prerequisites, such as FUSE and Python setuptools, but those are easily installed with the FreeBSD ports system. If I can get ElasticDrive to work, it will be handy to package it as a port for one-command installation.
In the mean time, I installed it manually and edited the /etc/elasticdrive.cfg to point to my Amazon S3 account. I reduced the size of the S3 backing store to a 100Mb disk:

#Path to fuse is the path to the device mount folder. NOT your fuse libraries

After I fired up the tool, I saw my ElasticDrive file:
fbsd70# ls -al /mnt/elasticdrive
total 102403
drwxr-xr-x  2 root  wheel          0 Dec 31  1969 .
drwxr-xr-x  4 root  wheel        512 May  7 13:36 ..
-rw-r--r--  1 root  wheel  104857600 Dec 31  1969 ed0
-r--r--r--  1 root  wheel        391 Dec 31  1969 stats
fbsd70# du -sh /mnt/elasticdrive
100M    /mnt/elasticdrive

Cool – this looks promising!

FreeBSD uses the mdconfig command to create a file-backed loop device, similar to the Linux losetup command. This is too easy:

fbsd70# mdconfig -a -t vnode -f /mnt/elasticdrive/ed0 -u 0
fbsd70# ls -al /dev/md0*
crw-r-----  1 root  operator    0, 101 May  8 12:32 /dev/md0
crw-r-----  1 root  operator    0, 106 May  8 12:32 /dev/md0a
crw-r-----  1 root  operator    0, 107 May  8 12:32 /dev/md0c
fbsd70# fdisk /dev/md0
******* Working on device /dev/md0 *******
parameters extracted from in-core disklabel are:
cylinders=12 heads=255 sectors/track=63 (16065 blks/cyl)

parameters to be used for BIOS calculations are:

fdisk: invalid fdisk partition table found
Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:

end: cyl 11/ head 254/ sector 63
The data for partition 2 is:
The data for partition 3 is:
The data for partition 4 is:

Ok, let’s create a filesystem and test it out:
fbsd70# newfs /dev/md0a
/dev/md0a: 100.0MB (204784 sectors) block size 16384, fragment size 2048
using 4 cylinder groups of 25.00MB, 1600 blks, 3200 inodes.
super-block backups (for fsck -b #) at:
160, 51360, 102560, 153760
cg 0: bad magic number

Woops – what’s this now?! Looking at the newfs source code, this error is generated when data read back from the disk doesn’t match data written to the disk.

I’ve tried to figure out what the problem is using truss and other techniques, and I’ve contacted ElasticDrive to see if they have any ideas. So far, nothing has worked.

If anyone else has an idea how to troubleshoot this, let me know.

Who’s Going To BSDCan 2008?

Filed under: Operating Systems — Tags: , , — Greg Larkin @ 4:15 pm

Hi everyone,

I just registered for the BSDCan 2008 conference in Ottawa, ON, Canada on 5/16 and 5/17. I’m really looking forward to meeting some of the folks that I’ve exchanged emails with over the past couple of years while learning and using FreeBSD and maintaining some ports.

Is anyone reading this post going to be at the conference, too? If you want to meet up, drop me a line and let me know. I hope to leave the conference with a lot of new FreeBSD knowledge and hear about how others use it and what to expect in future versions.

I’m also just looking forward to getting back to Ottawa. We’ve mostly visited there in the winter for the Winterlude and cross-country skiing at Parc Gatineau. If you enjoy freezing your tail off in mid-February (-30F at night not unheard of!) and skating on the Rideau Canal with 50,000 other fun-loving souls, you’ve got to visit!

I imagine that the warmer months will be very nice as well, and I do hope to see some of the Tulip Festival while I’m there.

Updated FreeBSD 7.0 VMware Image Now Available

Filed under: Operating Systems — Tags: , , — Greg Larkin @ 4:22 pm

Hi everyone,

I updated the ports tree and repackaged the FreeBSD 7.0 VMware virtual machine that turned out to be corrupted in my earlier release. I apologize for anyone who was inconvenienced, and I still don’t know how part of one of the disks was corrupted, since the source image was fine.

Anyway, you can find the new download here: VMware 7.0 virtual machine with ZFS enabled

If you run into any problems, please contact me.

Update: Need Help with VMware Workstation Running on Microsoft Vista

Filed under: Operating Systems — Tags: , — Greg Larkin @ 5:36 pm

Hi everyone,

In a previous post, I asked for assistance about getting a FreeBSD 7.0 virtual machine running on VMware Workstation on MS Windows Vista. Well, it turns out I didn’t need any help after all – the torrent file was corrupted!

Somehow, one of the 2Gb slices of the VM’s boot disk was truncated to ~1.4Gb. I don’t know how it happened – perhaps during the ZIP compression. It’s very odd, because the rest of the slices were fine.

Anyway, I’m preparing a new torrent, and I’ll post the link when it’s ready.

Need Help with VMware Workstation Running on Microsoft Vista

Filed under: Operating Systems — Tags: , — Greg Larkin @ 11:02 am

Hi everyone,

A couple of weeks ago, I made a FreeBSD 7.0 + ZFS VMware image torrent available on the BitTorrent Tracker. A reader of this blog contacted me a couple of days ago about a boot problem he’s having with the image, and I was wondering if anyone out there can reproduce it and/or provide a solution? Here are the particulars:

  • Host OS: Microsoft Windows Vista
  • VMware Workstation version 6.0.3 build – 80004
  • FreeBSD 7.0 + ZFS VMware image (torrent)

Initially, it appears that the VMware image ZIP did not unpack correctly, because this error is displayed:

VMware Workstation Error Message

However, checking the directory where the ZIP file was unpacked shows that the file does exist:

Virtual Machine Directory Listing

I tried to debug the problem from here since I don’t have Vista installed anywhere, but nothing has worked yet. He sees the same problem with VMware Player, too, so I wonder if it’s something to do with Vista permissions or some other security setting.

If someone has an idea what the problem could be, let me know.
