Has anyone heard if adding support for com.klarasystems:vdev_zaps_v2 to #illumos #zfs is somewhere on the roadmap?

Why BSDs in 2025?

My perspective and why we moved many services from Linux to the BSDs.

My friends, I'm so excited and happy to introduce a new project: the illumos Cafe!

The positive and constructive spirit of the BSD Cafe, created and maintained by all the friends who participated from day one in building a strong and friendly community, deserves to spread to other operating systems. Because there are other OSes that deserve attention, certainly more than they're getting right now.

Operating systems based on illumos (like SmartOS, OmniOS, Tribblix, OpenIndiana, etc.) are mature, stable, secure, and perfectly usable for a wide range of tasks. ZFS is native, zones are an excellent method for containerization, and bhyve and kvm coexist beautifully - and so much more, too much to list in a single post.

So from today, the illumos Cafe will stand alongside the BSD Cafe in creating a positive, respectful, and growth-oriented (but also relaxing!) environment, starting right here in the Fediverse with a Mastodon instance and a snac one.

I've written an introductory article about the project, including some technical details. I invite everyone interested to read it: https://it-notes.dragas.net/2025/08/18/introducing-the-illumos-cafe/

Choose your table, take a seat and enjoy your time at the illumos Cafe!

As soon as I finish reorganising my workspace so I can reach that unused ATX power supply, I'm going to build my new home server/living-room PC for my media collection. This will be my first time using ZFS for a pool with RAID-Z, wish me luck.
#linux #zfs #raid #raidz

@LordCaramac Good luck. RAID-Z isn't bad (though I would suggest considering double parity: RAIDZ2). You take a bit of a hit in terms of IOPS but the failure handling characteristics are better than two-way mirrors.

#ZFS

Today is Monday, 1st September. And September means one thing: EuroBSDCon!

23 days to go until EuroBSDCon 2025 in Zagreb!

I’m doing a little “advent calendar” for BSD fans: each day until the conference I’ll share one article from it-notes.dragas.net about FreeBSD, OpenBSD, NetBSD, DragonFlyBSD, ZFS, PF and more. The dedicated hashtag will be #EuroBSDConAdvent

Let’s start right away with "I Solve Problems" - my EuroBSDCon 2024 (and #BSDCan 2025) talk about migrating from Linux to BSDs:

https://it-notes.dragas.net/2024/10/03/i-solve-problems-eurobsdcon/

If you’re coming to Zagreb, reply to this post - it would be nice to meet up with fellow BSD users!

Voilà. C'est mieux. Une partition racine de 12 Go, 8 Go de swap (Proxmox en met automatiquement, j'ai donc limité). Ça me fait un petit 20 Go pour l'OS et tout le reste pour les VM ^^

En parallèle, mon pool ZFS a finit ces vérifications, j'ai pu faire l'export. Demain, je vais donc pouvoir déplacer physiquement les HDD et passer à la préparation des VM.

#Homelab #SelfHost #Proxmox #ZFS

Après une pause dans la mise en place, je reprends avec Groscopain, le NAS. Au lieu d'être installé directement sur Proxmox, je créé une VM dédiée sous Debian. Je bascule les HDD en passthrough et hop !

Ça va m'occuper ce week end ^^

#Homelab #SelfHost #Proxmox #Debian #NAS #SMB #ZFS

J'ai un disque en défaut dans mon pool ZFS. Je crois qu'il au même emplacement que les précédents. Les changer de boitiers va résoudre le soucis.

En attendant, je répare le filesystem avant de voir s'il fait le remplacer.

#Homelab #ZFS

Suite des aventures de Grosveinard et ses amis. Les disques ont bien déménagé, ils sont reconnus par le nouveau système.

Il me reste à gérer le passthrough de la carte PCI pour avoir tous les disques dans la VM qui va me servir de NAS.

Ensuite, je pourrais importer le pool ZFS et refaire mon samba.

Et tout ranger ^^

#Homelab #ZFS #Proxmox #Passthrough

Alt...

Photo d'un mini boitier de PC. Il est ouvert, laissant apparaître les composants, dont 5 disques durs. Les câbles sont encore en vrac.

Yeah ! Le passthrough s'est fait comme une lettre à la poste ! Maintenant, j'importe le pool ZFS !

#Homelab #Proxmox #Passthrough #ZFS

Bon, j'ai refait une installation propre et suis passé sous Trixie au passage. J'ai pu installer ZFS et le ssh fonctionne lui aussi. Il me faut le documenter pour ne pas oublier.

MAIS, mon pool ZFS n'est pas détecté, pourtant les disques sont bien présents.

#Homelab #Debian #ZFS

J'ai compris pourquoi le pool ZFS n'était pas importé. Il restait des scories de l'ancien OS (des storages Proxmox). En les virant, l'export se fait bien.

J'ai quand même dû forcer l'import ce qui me chafouine. En tout cas, le pool est là, il est bien monté.

Je documente et je reprends. J'ai une erreur "cannot share 'data: system error': SMB share creation failed" à creuser avant de faire la config Samba.

#Homelab #Proxmox #ZFS #Samba

Just saying #ZFS is amazing. Not only did it warn me when an 8 year old spinning drive threw an unrecoverable block error (and silently fixed it by moving data to working block), but it was also trivial to use zpool replace to put a new drive in. No downtime on this little NAS.

I'm thinking about setting up a replication target for the zfs pool on my server. Can anyone recommend a machine that needs little power, is fanless and can hold 2 SATA HDDs?
Is there such a thing?

My server is an HP small form factor desktop PC and I just could vet another one of those but the fan noise is a bit annoying.

Just published a comprehensive FreeBSD Cheat Sheet for Linux Admins!

Covers all the essentials:
- Hardware info (pciconf → lspci)
- Network commands (sockstat is amazing!)
- Disk management & ZFS operations
- Service management differences
- Package management across systems

Perfect for Linux admins diving into FreeBSD or anyone working across both systems. Includes 100+ command comparisons and real-world examples.
