Special FreeBSD install for a NAS

Posted on 2024-09-29 17:12:00 by Vincent in FreeBSD Nas

My last evaluation on other BSD has decided my to use ZFS for my NAS.

My OpenBSD is working since +8 years very well, but I'm at 85% of his capacity, so I have to replace/upgrade his capacity.

Despite my OpenBSD NAS offers a pseudo-snaptshot system via rsync, this little machine becomes too small and too old to manage and provide files of several GB we have today. So, why not replace the software when we have to replace the hardware ;).

Let's compare rsync with cpdup

Posted on 2024-09-14 11:12:00 by Vincent in OpenBSD Nas

I have more and more big files to transfer between my end user devices (laptop, mobiles, ...). The goal of this blog is to compare cpdup and rsync to synch files between my OpenBSD laptop and my NAS.

Today, files I'm managing are bigger and bigger. For example, with modern camera I often have +500 photos to transfer which represent +6GB of data.

Moreover, I'm an heavy user of hardlinks, so I want to make sure all my hardlinks are correctly reproduced on the NAS.

Make a read-only machine with OpenBSD

Posted on 2024-08-18 22:17:00 by Vincent in OpenBSD

In a post of 2016 I explained how to build a Read-Only OpenBSD machine.

Because in the recent OpenBSD systems we have new components, this post will update the situation.

I remind that a read-only machine is a machine where most filesystems are read-only. As consequence you can cut power of the machine without damaging the filesystems.

Personally, I'm using such system for my firewalls and my hifi OpenBSD system.

Easily have encrypted files on OpenBSD

Posted on 2023-08-21 19:43:00 by Vincent in OpenBSD

Since OpenBSD 7.3 the installation process allow you to encrypt your whole disk.

This is a nice security feature that most persons will activate on their laptop. Your CPU will increase effort to encrypt and decrypt all those files residing on your systems.

I don't know the real impact, but I estimate (via a simple and empiric measure) that full encryption could add an extra charge of 25% on my machine and thus on my battery.

This blog is for persons having an old and/or weak battery laptops running OpenBSD.

After +5 years, I propose a method to clean up my OpenBSD laptop

Posted on 2023-02-12 15:03:00 by Vincent in OpenBSD

After several years of doing upgrades, I discovered lot of unused files on my different system's folders: /usr/X11R6, /usr/lib, ...

What is really nice with OpenBSD is that "system" is totally separated from the user space.

In this blog I will present my method to clean up the "system" part, including firmware.
