There are 141 tips in the FreeBSD tips file that is displayed by fortune every time you log into a FreeBSD system. root@geonosis:~ # grep -E '^%' /usr/share/games/fortune/freebsd-tips | wc -l 141 Most of the time, I know the tips very well. Sometime, however, I do learn a new thing.Today I Learned thatTo set a quota of 10 GB for the user named foo on a ZFS dataset, run the following command: # zfs set userquota@foo=10G pool/home/foo The zfs userspace command can display the quota and current space usage: # zfs userspace pool/home/foo To unset a quota, assign "none" as the value. -- Benedict Reuschling <bcr@FreeBSD.org> This is actually two tips in one. First, is the userquota in a filesystem, and the second one is how to see these quotas, which I had no idea about.So I tried running it on one of my larger systemsroot@geonosis:~ # zfs list genomic/abi/proj/cfdna NAME USED AVAIL REFER MOUNTPOINT genomic/abi/proj/cfdna 39.9T 7.10T 39.9T /mnt/proj/cfdna root@geonosis:~ # zfs userspace -S used genomic/abi/proj/cfdna TYPE NAME USED QUOTA OBJUSED OBJQUOTA POSIX User 10039 22.1T none 78.6K none POSIX User 10017 6.64T none 102K none POSIX User 10048 6.35T none 110K none POSIX User 10052 4.51T none 7.11K none POSIX User 10011 326G none 1.34K none POSIX User 10065 1.42G none 14.7K none POSIX User 10012 51.3M none 1.77K none POSIX User 10001 125K none 13 none POSIX User 10018 38.1K none 3 none POSIX User 10031 1.50K none 3 none POSIX User root 512B none 1 none I don’t integrate our storage systems with LDAP, instead we just use the UIDs in permissions, but I can check who that is on another system.antranigv@ssh-02:~$ id -nu 10039 anahit Time to inform anahit that she has the record for most used storage in our largest project 🙂That’s all folks…

Seven years of running FreeBSD on ThinkPads alongside Linux — lessons I'd give my younger self<https://www.reddit.com/r/freebsd/comments/1tedyva/seven_years_of_running_freebsd_on_thinkpads/>＂I daily-drive Linux at work and FreeBSD on my personal ThinkPads (T480 & P52 currently). Both laptops and both operating systems, every day. I'm the kind of person who reads freebsd-update output and Phoronix benchmarks in the same hour.＂Recently saw the "is FreeBSD really that goated" thread and it brought back the timeline of my own journey. Started with a rough —call it version 0.9 — build that barely had X11 working, evolved through five iterations, landed on something I'd call "production-stable personal desktop" around version 2.0 on FreeBSD 15.0 with a heavily customized MATE, ZFS boot environments, BastilleBSD jails for microservices, WireGuard tunnels and PF.＂If I could send a packet back in time to my earlier self, here's what I'd put in the payload: …＂The image here is for <https://www.reddit.com/r/freebsd/comments/1tedyva/comment/om1t5mg/> because we can all agree that em dashes make scintillating conversation.#goated #X11 #Wales #FreeBSD #BSD #Linux #ZFS #OpenZFS #Beastie #daemon #MyLittlePony #unicorn #dolphin #rainbow #IBM #Lenovo #BastilleBSD #WireGuard #AI #purple

RE: https://mastodon.bsd.cafe/@stefano/114914266063275474I'm now upgrading the FreeBSD inside the red APU. This will be moved to the office and keep the backups of the backups.#IT #SysAdmin #ZFS #OwnYourData

Duplicating Your System: Using Duplicity to Back Up Your FreeBSD Desktop.In this Q1 2026 FreeBSD Journal article, Jason Tubnor walks through a practical approach to backing up your FreeBSD system using duplicity, including encrypted backups, incremental chains, parity protection, and S3-compatible storage.Read more:https://bit.ly/4d5AR1v #FreeBSD #OpenSource #ZFS #Backup #SystemsAdministration

I've been running two degraded ZFS arrays for the last few weeks (Debian host).Yeah, I know. Whatevs.One of the pools was basically "scratch" backup space and one of the spindles died (breaking the utility of the mirror). Pulled the drive, wiped the remaining, put back in service with minimum fuss as a single drive. I'll throw another spindle at it when drive prices drop again.The other array had the SSD cache die and it's been chugging along fine ever since. Not a big deal, but from a "experience" point of view it "feels slow" like a working md array. New SSD arrived in the mail so that'll get sorted sometime today/tomorrow.So, what's this post about?Linux peeps, if you are thinking about md arrays, just stop, take the time, and throw 'yer leg over the zfs horse. It's worth it.#Linux #RunBSD #zfs #md #mdadm #raid #homelab #SelfHosted #SelfHosting

If you're interested, I'm keeping track of what works (and what doesn't) on my laptop here: https://kedara.eu/freebsd-thinkpad-t14-gen2-intel/

@ax6761 thanks, I went with anacron: easy to setup, and now I can make full use of other periodic scripts.

@grahamperrin this looks interesting!Cc: @FreeBSDFoundation

@holdenweb some data is included, on purpose. They need to test an upgrade/performance path so they also need some of the data. Prod and dev are of the same customer, same dev.
