This blog post delves into the process of automatically unlocking a LUKS2 encrypted system partition using Clevis and TPM2. To start with, you need to ensure that Secure Boot and TPM are enabled in your BIOS settings. For Secure Boot, you may need to configure your system to trust third-party certificates, which could involve generating a new key pair and certificate for your system, signing your boot loader and kernel with the new key, and enrolling the key in your system's Secure Boot database.
The blog proceeds to guide you through the installation of the necessary packages for Clevis, using the command `sudo dnf install clevis clevis-luks clevis-dracut clevis-udisks2 clevis-systemd`. Once installed, the TPM2 key has to be bound to Clevis, which creates a key on the TPM2 chip and binds it to the LUKS2 encrypted system partition. You will be prompted to enter your passkey.
The final step involves updating the system files to use Clevis to automatically unlock the system partition...--GPT 4
ZFS is a modern file system with features such as copy-on-write, redirect-on-write, deduplication, and snapshots, making it suitable for large-scale storage and data management scenarios. It operates on the concept of storage pools, where a pool manages disks and provides storage space. Datasets can be created on top of these pools, which don't require allocated space and can utilize the entire storage capacity of the pool. Each dataset is mapped as a directory for file storage and organization.
The blog post provides a detailed guide on how to install ZFS, locate your disk, list sets and pools, and manage pools and sets. It also explains how to use the deduplication property to remove redundant data from your ZFS file systems, resulting in only unique data being stored and common components being shared between files.
Additionally, the blog post discusses the use of snapshots, which record the state of the file system at a specific point in time. This feature allows for easy resto...--GPT 4
