Mastodon

Welcome to Larvitz Blog! I’m Christian, a Cloud Consultant by day and FreeBSD enthusiast by night, with over 20 years in enterprise IT. Here I write about FreeBSD jails, PF firewalling, self-hosting, Linux system administration, and anything that’s cleanly engineered. Most articles are hands-on guides born from running my own infrastructure, from dual-stack networking and Ansible automation to hosting a Mastodon instance on FreeBSD.

Have a question or want to discuss something? Find me on the Fediverse at @Larvitz@burningboard.net. I’m always happy to chat!

FreeBSD Foundationals: ZFS - The Last Filesystem You’ll Ever Need

The second in the FreeBSD Foundationals series. This one covers ZFS from philosophy to practice: why it exists, how pools and datasets work, what checksumming and self-healing actually do, how to tune recordsize, compression, and atime, how encryption works with key management, how snapshots and the hidden .zfs directory give you time travel, and how ZFS send/recv turns backup and migration into a solved problem. Includes a look at sanoid/syncoid for automated snapshot management.
