Jumping into another cloud

After almost 4 years of being a Rackspace user I’ve moved to a new home – Amazon AWS. The main reason that gave me a nudge was the issue I was hit by after upgrading to 10.1-Release. Temporary solution did work but it was too costly to consider it as permanent so I started to […]

FreeBSD 10.1-Release as domU (guest) VM

I’ve been running FreeBSD 10.0-Release for quite a while using Rackspace’s environment and yesterday decided to jump on 10.1-Release bandwagon using exactly the same steps which I described in on of my earlier posts. However it wasn’t successful as expected since I see constant freezes with the following errors being displayed in the console: network_alloc_rx_buffers: […]

What the heck are all those terms – PV, HVM, HVM with PV drivers, PVHVM, PVH?

If you have to deal with Xen from time to time and not on a permanent basis and want to refresh the difference between all those Xen modes, I strongly encourage everyone to read the following two outstanding articles: The Paravirtualization Spectrum, part 1: The Ends of the Spectrum The Paravirtualization Spectrum, Part 2: From […]

Installing and configuring Graphite with Collectd on FreeBSD

Using Graphite for a smidgen blog like mine is definitely an overkill and Munin fits much better but I wasn’t able to confront my curiosity. So that’s why this post. Before I start, I’d like to mention that even if I’ll be speaking about my endeavor with Graphite on a system running FreeBSD 10.0-RC5, the […]

Another web server powered by FreeBSD

During the last couple of days I’ve been migrating data and various configurations from my old Ubuntu server to a new one which is running FreeBSD 10.0-RC5 now.

Upgrading FreeBSD 9.2 to 10.0-RC4 on Rackpsace’s instance

In reality it turned out to be a fairly straightforward procedure: This is crucial. You must save XENHVM config before the upgrade otherwise you won’t be able to re-build the kernel which is required to bring the network up. # cp /usr/src/sys/amd64/conf/XENHVM /root/amd64_XENHVM # cp /usr/src/sys/i386/conf/XENHVM /root/i386_XENHVM Perform the upgrade as usual and just follow […]

Grow root ZFS pool online under FreeBSD 9.2 using Rackspace’s instance

If you opted for a FreeBSD instance on Rackspace and chose standard configuration then you’ll end up with 512MB of RAM and 20GB of space. That’s ok for the starter but eventually you’d need more one day and will upgrade RAM to 1GB for example. With this upgrade your disk will grow upto 40GB but […]

How the SCP protocol works

That’s not my title but the one I stole from a fantastic Jan Pechanec’s blog post that describes how the SCP protocol works – I really encourage everyone to read it.

FreeNAS with MegaRAID SAS 9240-8i

Recently I’ve been involved in a small project to add a support for MegaRAID SAS 9240-8i into FreeNAS 0.71. To tell the truth it was fun since I haven’t been tinkering FreeBSD for quite a long time. Anyway, if you need a support for this card in your FreeNAS installation just download and unpack the […]
