This article examines the recovery of KVM/QEMU virtual disks and snapshots from a storage system built on LUKS2 and RAID 6. The focus is on determining the correct recovery sequence, safely working with physical disk images, reconstructing the RAID array, unlocking the encrypted container, locating QCOW2/RAW images, analyzing the backing chain, and restoring access to virtual machine data without modifying the original media.

Recovering data from Linux MD RAID 6, additionally protected by LUKS and fscrypt encryption, is a complex multi-layer process in which it is important to correctly determine the state of the RAID array, the sequence of disk connection, and the encryption layers. An error at any stage, from incorrectly assembling the array to attempting to mount a damaged file system, can significantly complicate subsequent recovery. This article describes a safe approach to diagnosing and reconstructing RAID 6, opening the LUKS container, and further working with data protected by fscrypt.

In this article, we will examine the process of recovering data from virtual machines and snapshots located on LVM-Thin block storage in a Proxmox Virtual Environment 9.1.1 environment. We will analyze the most common data loss scenarios faced by administrators and users. We will also cover how to diagnose the state of disks, connect drives directly to a computer, and recover data using specialized software.
