Well I gotta say, moving #MastodonAU 's database to a pure SSD storage backend has made a massive difference. Whooohoo, she's much faster! The storage servers are a pair of #Dell R640s, with 2x Gold 6150 (2.7GHz 18 Cores each) and 256GB of RAM. Each one has 8 x 1TB SSDs, in a #ZFS raidz2 pool, and they automatically replicate between themselves. I am doing my best to avoid any more visits from the #fuckup-fairy Now to finish #MastodonNZ

With Apple phasing out AFP in macOS 27 and Time Capsules officially reaching end-of-life, it's time to move network backups to proper SMB. If you run a FreeBSD server, you can build a fast, rock-solid, and secure Time Machine target powered by ZFS and Samba - neatly isolated inside a FreeBSD jail using Bastille. https://it-notes.dragas.net/2026/01/28/time-machine-freebsd-jail/ Keep your macOS backups running smoothly via SMBv3 (with full vfs_fruit support) and full dataset quota control on ZFS! #FreeBSD #macOS #TimeMachine #ZFS #BastilleBSD #Samba #SysAdmin #Backup #OwnYourData #SelfHosted #BSD #RunBSD #OwnYourData

How much disk space does it take to reliably track & scan all the important open-source software releases published throughout the year? About 120TB. Thanks to #FreeBSD, #ZFS, #WesternDigital, and #Ampere for being awesome. :)

Nearly two years ago I noticed one NVME disk had endurance gone down to zero. It has been part of ZFS RaidZ3 six drive pool under constant write load. Normally I would replace such drive. But this time I decided to see how long it takes to break it. And the answer is - almost two years. The disk receives few MB/s writes *minimum* with hundreds MB/s peaks, maybe 100TB writes per year. I'll try to dig some numbers later. So, looks like there is ample headroom in NVME write endurance claims. (statistics from sample of one 🤣 ) I think I'll let the pool run sans one drive.It should survive two more drive failures. And there are daily/weekly/monthly backups available. Maybe buy new after AI bubble bursts. #homelab #zfs #diskfailure

All #BSD and #ZFS wizards alert Please focus all your mojo on helping the people who posted the ZFS/BSD admin job that I just applied for to see that I am their dream come true.

slopified os Hover or focus to reveal Sensitive
Noticed 2 threads on the same subject around the same time where OPs are seeking un-slopied OS(-adjacent) ... by @sharpcheddargoblin@reclusive.blog- https://reclusive.blog/@sharpcheddargoblin/statuses/01KXK87ZWXFEZX3HMCV245XYNV by @underseamonkey@fosstodon.org- https://fosstodon.org/@underseamonkey/116925448044314424 ... in that regard alone -- not accounting for hardware support or available software -- #NetBSD, followed by #OpenBSD, may be best bet for now among {Free,Net,Open}BSD. Mind that #ZFS of NetBSD is from pre-OpenZFS era. I will be happy to be corrected on this. ... #noAI

A couple of days ago, few hours before leaving home for a four days trip I decide to upgrade one of my home servers to FreeBSD 15.1. Nothing difficult. After upgrade the machine start rebooting in a loop. I pick up my serial cable and see the boot process crash when mounting ZFS panic: zfs(panic): zfs: rt={spa=zroot vdev_guid=546977716602668702 ms_id=9 ms_freed}: adding segment (offset=2431c0000 size=1000) overlapping with existing one (offset=2431c0000 size=1000) 😬 that's terrible. I relay on this machine to access my nextcloud where all my trip tickets are stored. Hopefully ZFS saves my day! I was able to boot back to the previous snapshot, and smoothly restore the service, but I probably need to start thinking in a replacement for this machine.... #FreeBSD #ZFS

Hey #FreeBSD Questions about migrating some dockerized services from Linux. *By the way, for those who noticed my #ZFS post from a day or two ago, good news: It wasn't the drive that was dead! It was either motherboard, of which I have functional spares at hand, or the 750w power supply, but I strongly suspect the motherboard, which is old enough to have classic PCI slots on it. The array is absolutely fine and the server's back up with my newest mobo and sadly, an i3. If you have an LGA1151 i7 CPU (either 6th-7th or 7th-8th gen Intel, can't recall) that you're not using and want to donate it to the chezpants.ca cause, dm me * Anyways, I decided to give FreeBSD another go, since this is primarily a ZFS-based file server, and since I started listening to @25admins@mastodon.social they've been seducing me back to the ummm Dark Side. My first and only Sysadmin job was BSD-heavy, and it truly is a vastly superior server experience than anything else out there. But I was running several services on that metal with Docker as well, and while in theory I can install Podman and bring those back up, I would rather embrace native solutions where possible. The Jellyfin container is already running the pkg version, flawlessly. I got a little confused when attempting to setup ports, so I'm just going with pkg for now. Other stuff to replace is FreshRSS, Pi-Hole, Mealie, and I intend to get some kind of ebook utility with a web UI up. Other stuff too, but those are the daily use ones that I need to replace like today. I have heard that Blocky is the predominant Pi-Hole alternative? I haven't looked into Mealie yet, and FreshRSS doesn't have a supported BSD install, so I'd rather try out some other RSS util that does, if there's one that's worth a damn. WebUI as well, please - I am aware there's a terminal based one and I might install it for shits and giggles but I want to see the pictures and whatnot, generally. Oh, and also I'm gonna go ahead and tag @stefano@mastodon.bsd.cafe cause he seems to be a pretty good authority on running services on BSD - in fact I think bsdcafe has FreshRSS, even?

Thought I was real clever, building a 4x16TB #zfs array for our server, umm... guess it was a good six years ago now. They cost CDN$400 round then. Think of the hydro, I said! Today, I'm pulling the old 6x4TB that that array replaced, pruning what data I can from the currently-degraded 16TB array in order to transfer it over, and then rebuilding it as a 3-drive zpool for non-critical data, cause holy shit we cannot afford 16TB drives right now. I might even just use em as straight 16TB drives, why even bother with the pretense that I could replace one... (I know that the math adds up the same when replacing hard drives, TB for TB, but we can handle the failure of a 4TB drive as an unanticipated money hit. A 16TB drive, that's been elevated to "tax time luxury purchase" costs)

FreeBSD 15.1-RELEASE is out. In my new guide, I walk through the official upgrade paths: • distribution sets with freebsd-update • packaged base with pkg • boot-environment rollback • .pkgnew merges • boot-loader checks for UEFI/BIOS https://blog.hofstede.it/upgrading-freebsd-150-release-to-151-release-the-official-paths/ #FreeBSD #BSD #Sysadmin #ZFS

New on the blog: FreeBSD Foundationals #3: The Boot Process

From power-on to login: BIOS vs UEFI, the loader & loader.conf, why a tunable is NOT a sysctl, loading modules the modern way with kld_list, wrangling it all with sysrc, plus a security-hardening baseline.

And the headline act: boot environments. bectl create before every upgrade. When freebsd-update or pkg eats your box, you reboot, pick the old BE in the loader menu, and you're back in 30 seconds.

IT-Sicherheit 2026: Nicht ob, sondern wann. Die Bedrohungslage hat sich fundamental verändert. KI-Systeme decken täglich neue, oft kritische Schwachstellen auf – in einem Tempo, mit dem selbst die größten Softwarehersteller kaum Schritt halten können. Zero-Day-Lücken bleiben oft tagelang oder wochenlang ungepatcht. Patchmanagement ist wichtig – aber es reicht längst nicht mehr aus. Die unbequeme Wahrheit: Es ist keine Frage mehr, ob ein Unternehmen Ziel eines Angriffs wird – sondern wann. Umso entscheidender ist der Aufbau einer widerstandsfähigen IT-Infrastruktur. Was das konkret bedeutet: Netzwerksegmentierung mit moderner Firewall-Technologie – z. B. mit OPNsense: eine Open-Source-Lösung, die enterprise-taugliche Features wie IDS/IPS, VPN und granulares Regelwerk mitbringt – ohne Enterprise-Preisschild.Konsequentes Need-to-Know-Prinzip bei ZugriffsrechtenModerner Virenscanner mit Prozesserkennung & VerhaltensanalyseBackup & Verfügbarkeit durch den Einsatz von Linux/Unix-Systemen mit nativen Snapshot-Funktionen und dem bewährten Dateisystem ZFS – extrem stabil, selbstheilend und ideal für ein mehrstufiges, an die jeweilige Kritikalität angepasstes Backup-Konzept.Regelmäßige Schwachstellenscans zur proaktiven RisikoerkennungPentests durch externe Partner, weil ein frischer Blick von außen oft das aufdeckt, was intern übersehen wirdKlingt aufwendig? Mit dem richtigen Partner ist das oft schlanker umsetzbar als gedacht – und der ROI lässt sich ganz einfach berechnen: Was kostet ein erfolgreicher Angriff im Vergleich zur Prävention? Wichtig dabei: Ein guter Partner muss nicht zwingend aus dem Ökosystem der großen internationalen Anbieter kommen. Im Gegenteil – wer auf Linux/Unix-affine Lösungen setzt (z. B. FreeBSD auf Servern, OPNsense als Firewall, ZFS als Storage-Backbone), reduziert Abhängigkeiten, Lizenzkosten und Angriffsfläche gleichzeitig. Eine pragmatische Mischung bleibt natürlich möglich: Windows auf Clients, offene Systeme im Serverbereich. Gerne tausche ich mich dazu aus. Wie ist eure Organisation aufgestellt? #ITSecurity #Cybersecurity #OPNsense #Linux #FreeBSD #ZFS #ZeroDay #Pentest #Backup #OpenSource
