Moving ZFS datasets around eases the transition from CVSup to Subversion
I upgraded some of my virtual machines during my summer holiday. They are all running ZFS, but were neglected for so long that they were still updating their source and ports trees using CVSup. I began pondering how to migrate to Subversion with the least fuzz possible. Luckily, I had anticipated the switch to Subversion, […]

I’ve been experimenting with FreeBSD 10.0-CURRENT and an alternative ZFS layout for more than a year. The idea is to have a simple way of switching between boot environments. Thus, you have the opportunity of reverting to a previous boot environment without resorting to snapshots and rollbacks as you would with a sole boot environment. […]

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.

My endeavour with ZFS on NetBSD/amd64 6.0.1 in late February and early March 2013 hasn’t been very positive. The kernel panics every now and then, even during the simplest of operations such as creating a new directory on a ZFS filesystem. The system was installed using UFS for the root filesystem, and the system was […]

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 found my old ZFS snapshot script rather useful and wanted to improve it. Unfortunately I used the GPLv2 license in the original script. To accommodate my friend, I have re-released the snapshot script under the 2-clause BSD license. Feel free to use whichever license, 2-clause BSD or GPLv2, that suits your needs.

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 […]

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.

George Mamalakis was having trouble with ZFS not detecting and utilizing his resized GPT freebsd-zfs partitions. Marco van Tol came to the rescue with a corrective procedure. Credit goes to George Mamalakis for raising the issue and to Marco van Tol for the solution. I’m just a simple bystander in comparison to these two, fine […]
