Why You Should Keep Your ZFS Pool Below 80% Capacity
ZFS pools should ideally stay below 80% capacity to maintain performance and reliability. Exceeding this limit can lead to slow write speeds, increased fragmentation, inefficient space allocation, and prolonged scrub or resilver times. This article explains the technical reasons behind this recommendation and provides best practices for keeping your ZFS pool running efficiently.

Why ashift Matters in ZFS: Getting It Right for Performance and Longevity
With ZFS, ashift is your key to matching your drive’s stride. Choose the right size for your disk to keep writes quick and wear low. Set it too small, and it trips over itself; too big, it overpacks space. Get it spot-on when you begin, and enjoy a smooth, lasting storage setup.
Automating Proxmox (PVE) Shutdown: A Simple Guide
Proxmox VE provides a straightforward way to manually shut down your server, ensuring all virtual machines (VMs) and containers stop gracefully. However, if you need to schedule automatic shutdowns, the web interface lacks a built-in scheduler. In this guide, we’ll explore how to manually shut down your Proxmox node, set up an automated shutdown using cron, and configure the startup and shutdown order for your VMs.
Migrating VMs from Hyper-V to Proxmox
Migrating virtual machines from Hyper-V to Proxmox allows you to leverage the flexibility and features of Proxmox VE. This process involves exporting the VM from Hyper-V, converting the disk format from VHDX/AVHDX to QCOW2, and configuring the VM in Proxmox. With this step-by-step guide, you’ll ensure a smooth and efficient transition, preserving your VM’s settings and performance while preparing it for optimal use in Proxmox.
