#zfs — Public Fediverse posts

As I sent out a personalised invite to the #AusNOG crowd to join MAU, I thought you lot may be interested in how #MastodonAU (and #MastodonNZ) connects to the interwebs!

MAU and MNZ (and related things) are hosted mostly in a datacenter up here in #Gladstone (Central #Queensland, #Australia).

I have redundant paths to Brisbane - one 9G connection to #NextDC B1, and a 10G Wave to B2.

I peer with #EdgeIX in both B1 and B2, #IXAU in B1, and Aussie Broadband and Telstra up here.

All this networking and redundancy and stuff is why it is REALLY REALLY ANNOYING that something dumb like 'I forgot to enable #VRRP on the Mastodon edge router' causes everything to fall apart.

The backend is #VyOS and #Mikrotik routers/switches, with #Proxmox for the virtualization, #Ubuntu for the OS's and #ZFS for the storage.

I'm also an #IPv6 guy, so everything is IPv6 enabled. In fact, I love it so much, I own the website. https://ipv6.com.au/

Oh, the reason all this infrastructure exists is because of my real job - https://aussievoip.com.au/ - So if you want #VoIP, or #SIP phones, you know a guy.

Ich habe mal wieder einen Fall von "Kleiner Fehler - große Wirkung" erlebt. 🤷‍♂️🤦‍♂️🤣

Ich habe vor 2 Tagen ein #Backup meiner #TrueNAS #VM in #Proxmox zurückgespielt. Nach dem Booten hat mir TrueNAS den #ZFS Pool "Data" als unhealthy angezeigt.

Ursache: Dieser liegt auf 2 16 TB SSDs, die in Proxmox in die VM durchgereicht sind - und offensichtlich ist diese Durchreichung nach dem Rückspielen eines Backups nicht mehr vorhanden. Gut zu wissen.

Also die HDs wieder durchgereicht und die TrueNAS VM neu gestartet. Passt.

Dann liefen allerdings in den vergangenen 2 Nächten die Backups der VMS nicht mehr durch, weshalb alle VMs - leider auch der #Homeassistant - in einem nicht erreichbaren Zustand hängen geblieben sind. 😠

Ein I/O Fehler bei der für das Backup temporär angelegten VM-Konfigurationsdatei unter '/etc/pve/nodes/c2b-pve/qemu-server' brachte mich erst auf die falsche Spur - ich dachte schon shit, jetzt auch noch Probleme im Dateisystem von Proxmox.

Doch am Ende - zum Glück - weit gefehlt. Nach dem Durchreichen der HDs in die VM hätte ich diese auch wieder vom Backup ausschließen müssen. Da ich das nicht gemacht habe, lief während des Backups aller VMs schlicht und ergreifend das Backup-Laufwerk voll.

Nach dem Ausschließen der HDs vom Backup lief der testweise auf 12:45 vorverlegte Backup-Cronjob wieder erfolgreich durch.

Kleine Ursache - große Wirkung eben 🤣

💾 OpenZFS 2.4.4 a fost lansat: Suport pentru Kernel-ul Linux 7.2 și un nou utilitar de recuperare MMP!

A fost lansată versiunea de mentenanță OpenZFS 2.4.4, oferind compatibilitate cu cele mai recente kernel-uri Linux, precum și unelte noi menite să ajute administratorii de sistem la recuperarea stocărilor afectate de erori complexe de rețea sau de blocare.

✨ Noutățile principale din OpenZFS 2.4.4:

🐧 Suport extins pentru Kernel-ul Linux 7.2:
• Adaugă compatibilitate completă cu seriile recente de kernel Linux 7.2 și 7.1, permițând utilizatorilor de distribuții rolling-release sau Enterprise să actualizeze sistemele fără riscul de a pierde accesul la pool-urile de date ZFS.

🛠️ Utilitar nou pentru recuperare MMP (zpool mmp):
• Introduce o unealtă dedicată pentru gestionarea caracteristicii MMP (Multi-Host Protection). În cazurile în care un pool este blocat greșit din cauza unor întreruperi de rețea sau probleme la nivel de cluster, noul instrument le oferă administratorilor posibilitatea de a verifica starea de blocare și de a forța recuperarea în siguranță a datelor.

⚡ Optimizări de performanță și stocare:
• Îmbunătățiri la nivelul gestionării memoriei cache ARC (Adaptive Replacement Cache) pe sisteme cu memorie masivă.
• Corecții pentru prevenirea degradării performanței la operațiunile de scriere/citire intensive în medii virtualizate (KVM, Proxmox VE).

🐛 Măsuri suplimentare de siguranță și bug-fixes:
• Rezolvă câteva cazuri particulare de închideri neașteptate (kernel panics) apărute la montarea/demontarea volumelor criptate și îmbunătățește stabilitatea modulului ZFS pe sistemele FreeBSD.

O actualizare esențială de infrastructură pentru serverele și sistemele de stocare NAS ce se bazează pe fiabilitatea sistemului de fișiere OpenZFS! 🚀

Infinito.Nexus 12.0: From a Single Server to a Scalable Sovereign Cloud

https://blog.infinito.nexus/blog/2026/08/08/infinito-nexus-12-0-from-a-single-server-to-a-scalable-sovereign-cloud/

Virtualization is a turbulent topic. Enterprises use enterprise systems. What can the small businesses do? Bhyve is a strong system for them.

I am experiencing this with #OpenZFS

errors: No known data errors

This has already happened, but at a point where I didn’t mind losing the data, so I destroyed the pool and I recreated it from scratch, with no errors. Now, I would like to try to repair the corrupted data… Any tips? I would hate it if I have to throw away the hard disk, it’s less than one year old and I have been using it only for a couple of months… Is replacing the disk my only option?

@jselea Thanks goes out to Jonathan for this (still quite relevant) tidbit. For those of us who spent a lot of time with Sun #Solaris up through Solaris 10 there's a lot to appreciate here.

Solaris has been parted out, but here is an Enterprise production scale incarnation that's worth a looksee and testdrive. It's really a shame that the Evil EllisonCo destroyed so much - just discarded it like trash, following aquisitions, and what they didn't toss out in the trash they dissappointed the developers so much that it spawned forks that exist to fill the vacuum to this day:

- MySQL ==> MariaDB
- OOo ==> LibreOffice (The Document Foundation)
- Sun Enterprise Servers - rebranded as Oracle boxes
- Sun Solaris 10 ==> OpenIndiana and others (OmniOS, for one)
- Sun VirtualBox - Oracle VirtualBox

So without dwelling on the past or further ado, let's follow Jonathan's tour, shall we?

A 50 minute show-and-tell, about #AHAlodeck, and how #xattrs on #ZFS can be used as #DataCentric catalog/environment.

Enjoy!

@mwl agreed: documentation.

#40 - FreeBSD 'system requirements' are not documented at the Project site or the documentation portal - grahamperrin/freebsd-doc - Codeberg.org — <https://codeberg.org/grahamperrin/freebsd-doc/issues/40> (2023). There's a reminder that in the past, the FreeBSD Handbook did include minimum hardware requirements.

In 2025 I took the issue to Bugzilla for FreeBSD. Less than an hour later, it was rejected: <https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=287722>.

Ich brauche nochmal #Brainpower der #EDV #Bubble 🤣

Da mein bisheriges, betagtes, leistungsschwaches 1-Bay #QNAP #NAS sehr langsam ist, z.B. beim #rsync, habe ich inzwischen das #Ugreen #NAS #DPX2800 gekauft, mit 32 GB #RAM aufgerüstet und 2 #NVNE mit je 2 TB eingebaut.

Azf den beiden M.2 ist #Proxmox im #ZFS #RAID1 installiert. #Homeassistant und #TrueNAS laufen je in einer #VM.

TrueNAS soll nun einen #Datenpool in Form eines verschlüsselten ZFS RAID 1 auf 2 16 TB Festplatten bekommen. So weit so gut.

Nur: Wie bekomme ich die #Daten vom alten NAS, die in einer verschlüsselten #LUKS #Partition liegen, in den Datenpool?

Über #Netzwerk kopieren ist keine wirkliche Option. Das ist für ~ 10 TB Nutzdaten viel zu langsam.

Bitte #Boost für mehr Reichweite. 🙏

For anyone who wonders about the absence of system requirements for FreeBSD:

― the two bug reports linked from https://www.reddit.com/r/freebsd/comments/1lcm1ze/freebsd_system_requirements/ may be of interest.

I reopened the first report following premature rejection.

Rejection of the second report is a concern, but not my concern. In the absence of documentation, everyone loses.

ProxMox Load Balancer

A new version is released.

If you deal with ProxMox in any form you'd be wise to see what this powerful tool can do for you. When you realize it is one of the tools you've been missing in managing your different VMS in ProxMox, rest assured you will be very glad you now know of its existence.

Without going into too much details because, I want you to read the documentation yourself, you know that when you need to move a VM from One ProxMox controlled server to another one, there are procedures you need to follow

You also know that when you need to balance the load on your different servers, by which I mean your Hardware Servers, you also know that from time to time, you literally need to move a number of VMS(!) from one server to another, in your server cluster or Server clusters, plural. You know how much time that can take.

Now go read your docs, I've inspired you
