💾 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! 🚀

has anybody seen #btrfs running terribly vs #zfs in #proxmox because i tried it (on platters) using raid10 and it ran AWFUL. re-installed using #zfs and it runs great. maybe something to do with restoring backups and them becoming .raw files that mount as ext4 loop devices? io was 20%+ idle. zfs is 0-10% with peaks here and there.

Nachdem #froscon Init habe ich mir bisher die beiden Talks zu #Proxmox angesehen. Zum einen #Pegaprox 1.0 und zum anderen #MicroVM (per Kvm/Qemu) sollte ich mir wohl mal ansehen.

Mission erfüllt! #ceph #cluster läuft mit 6 OSDs und der backbone schnurrt wie ein Kätzchen. Stromverbrauch ist mir zu hoch, werde mir aber bissel Zeit lassen und rum experimentieren. Gibt noch viel zu tun!

i've been running into this and it is a new phenomenon. smb on #proxmox for backups is broken.

[ Blog ] How to install #Nakivo on #Proxmox VE

If Proxmox VE is the virtual environment used to run your virtual machines, you need to install Nakivo on Proxmox to protect your workloads.

Proxmox VE is officially supported starting from Nakivo 11 allowing to #backup and restore running virtual machines.

To install Nakivo on Proxmox, you have the option to install the software on the http://rviv.ly/clDoHO

[ Blog ] Proxmox upgrade #Ceph #Reef to #Squid

If you are running Ceph Reef in your #Proxmox infrastructure and plan to upgrade to Proxmox 9, you must first upgrade Ceph Reef to Squid to meet the prerequisites.

As a best practice, before proceeding with the upgrade make sure to have a working backup of your VMs and Containers.

[ Blog ] Veeam #Worker on #Proxmox VE: "Cannot access a closed Stream" error

When you try to #deploy a Veeam Worker in a Proxmox VE environment, you might encounter the error "Cannot access a closed Stream".

This error prevents the Worker from deploying correctly and, consequently, stops you from backing up the Proxmox VE platform.

I run most of my stuff on Debian LXCs inside Proxmox.
For some things I would like a VM more, but since Debian 10 I have not had a Debian Upgrade that didn't broke my installation.

I am now looking at FreeBSD for VMs, trying out a lot, and seeing that most of my usecases work flawless.

Will upgrades for FreeBSD still brick my installs?

[ Blog ] How to properly #boot a migrated Windows vSphere VM in #Proxmox

To properly boot a migrated Windows vSphere VM in Proxmox during a migration, you must follow a specific procedure.

Windows VMs are quite sensitive to virtual platform changes. This is because the storage #controller configured in the source environment often causes issues, the mismatch between the original controller http://rviv.ly/xrzs9h

I thought setting up #Proxmox backups would involve learning and fiddling to connect my VE to the PBS, and it wasn't urgent so I had put it off for months.

In practice it was trivial and took <5 mins even the first time. In future it would be seconds because all I had to do was find the dialogue and choose a few options which all have clear help.

I haven't tried using one yet though 🤣

As a side note, UEFI + ACPI are required, so Raspberry Pi-style device-tree-only boards aren’t supported. VMs and live migration stay architecture-specific.

2/2

As a user of vmware/vsphere for 15 years, proxmox delights me in lots of small ways.
I'm currently live migrating a VM between 2 disconnected/separate #proxmox clusters, and it just works.

TIL: if you need to activate Windows11 in a #Proxmox VM on "shipped with windows" hardware, you can still follow this forum post from 2020 (https://forum.proxmox.com/threads/passthrough-hardcoded-windows-license.72767/)
edit the <PVE_ID>.conf of the machine and it activates automatically.

Machnmal finde ich die Typisierung der #proxmox api schon sehr spannend:

```
proxmoxer.core.ResourceException: 400 Bad Request: Parameter verification failed. - {'delete': "type check ('boolean') failed - got 'True'"}
```

Vorsicht beim Einsatz des #Proxmox #Backup #Server (#PBS). Das #Restore kann bei Proxmox VE 8 und 9 dazu führen, dass der Vorgang hängt - und laufende #VMs #beschädigt werden. Das Ganze wird seit Freitag (14.8.2026) vom Proxmox-Support untersucht.

muddled through vlans. probably should have got the next size switch but i can defer that for now. next up is some #proxmox fiddling, another thing i know next to nothing about

i can't say i dislike this per say, but it's probably fortunate that ccna classes in high school were kinda a bust.
