ZFS Pool Management Guide (Debian/Ubuntu) Introduction ZFS (Zettabyte File System) is an advanced filesystem and volume manager for large storage pools, offering snapshots, compression, and redundancy (e.g., mirror, RAID-Z). This guide shows how to initialize disks with GPT, create a ZFS pool, use stable device identifiers (/dev/disk/by-id/ or /dev/disk/by-partuuid/), support various RAID types (mirror, RAID-Z1, RAID-Z2), and mount datasets for normal user access on Debian/Ubuntu. ⚡ Quick Start ℹ️Info New to ZFS?

LVM RAID Management Guide (Debian/Ubuntu) Introduction Logical Volume Management (LVM) is a flexible storage management system that abstracts physical disks into logical volumes, allowing dynamic resizing, snapshots, and RAID configurations. LVM RAID integrates Linux software RAID (mdadm) with LVM to provide redundancy and flexibility. This guide explains how to create, modify, and manage an LVM setup with RAID on Debian/Ubuntu systems, covering volume group creation, logical volume setup with RAID, and maintenance tasks. ...

LUKS Disk Encryption Management Guide (Debian/Ubuntu) Introduction LUKS (Linux Unified Key Setup) is a standard for Linux disk encryption that provides a platform-independent way to encrypt block devices, such as partitions or entire disks. It supports multiple passphrases (keys), secure key derivation, and integration with other storage layers like LVM or ZFS. This guide explains how to create, modify, and manage encrypted disks with LUKS on Debian/Ubuntu systems, covering setup, key management, mounting, and maintenance. ...
