Symptom & Impact
Logical volumes are missing after boot and services fail to mount data paths.
Environment & Reproduction
Common after hardware changes, UUID changes, or restrictive LVM filters.
Root Cause Analysis
Volume group scan/activation is skipped by bad filter or boot ordering.
Quick Triage
Check visibility with `sudo vgscan –mknodes && sudo vgchange -ay`.
Step-by-Step Diagnosis
Review `lvm.conf` filter rules and confirm initramfs includes required modules/devices.
Solution – Primary Fix
Correct LVM filters, rebuild initramfs, and re-enable automatic activation at boot.

Prevention & Hardening
Keep filter rules minimal and validated on representative hardware.
