FreeBSD is approaching 20 years! I guess it all depends on what you regard as FreeBSD’s true birth. The baptism, the first commit to the CVS repository, the first release, or something else? The first commit to the CVS repository was done on “Sat Jun 12 14:49:13 1993 UTC”. That’s 20 years and 6 days […]

If you store files in the root file system of a zpool, it’s probably not so straightforward to access them from a different system, e.g. a live CD/DVD. Don’t panic. Here’s how.

I’ve been experimenting with carp(4) on FreeBSD/i386 10.0-CURRENT and FreeBSD/amd64 10.0-CURRENT for the past year or so. carp(4) is no longer a pseudo-interface, but rather accessible on every conceivable interface.

Today, I decided to upgrade PostgreSQL from 9.1.5 to 9.2.0 on one of my computers. Ironically, PostgreSQL 9.2.1 was released today, but until the FreeBSD ports hierarchy catches up, the most recent version available is 9.2.0, unless of course you want to do everything yourself.

Not long ago it was announced that the FreeBSD ports tree will cease exporting its Subversion repository to CVS, and subsequently any use of CVSup for updating the ports tree will be discontinued by February 28th 2013. FreeBSD’s main source tree repository has been served by Subversion since late May 2008 with every commit done […]

Someone named “Edward M” posted on the freebsd-questions mailing list a question of when should we create a ZFS filesystem. I didn’t reply to any of the messages, but I decided to write this post expressing my view. In short, whenever a part of the filesystem hierarchy exhibits different characteristics, create one or more ZFS […]

Jeg børstet støvet av noen tilårskomne filer forleden dag. Jeg fant et lite program som jeg skrev en gang i 2000. Programmet teller ned til slutten av Unix-epoken. Den opprinnelige definisjonen av datatypen time_t, 32-bit heltall med fortegn, vil få overflyt i midten av januar 2038. Moderne 64-bit OS som FreeBSD/amd64 9.0 har for lengst […]

If you trust your users well, you might feel slightly less anxious and allow your users to create new filesystems below their own home directories.

One of my systems is running FreeBSD/amd64 9.0-STABLE and is using ZFS for all its worth. The amount of installed memory in this system is 8 gibibytes, which should be enough to please even ZFS’ ARC. After a few hours of uptime not everyone are happy, and one of those unhappy guys are GnuPG.
