Symptom & Impact

VG activation fails with `Couldn’t find device with uuid` after replacing a disk.

Environment & Reproduction

Happens when LVM metadata references a UUID no longer present on the host.

Root Cause Analysis

Replacement disk has a new UUID and the VG has not been repaired to match.

Quick Triage

Inspect VG state with `vgdisplay` and missing PVs with `pvs -o +pv_missing`.

Step-by-Step Diagnosis

Identify the missing PV UUID and the affected logical volumes.

Solution – Alternative Approaches

Restore VG from `/etc/lvm/backup/` if metadata is intact.

Verification & Acceptance Criteria

Volume group reports clean state and all LVs activate.

Rollback Plan

Restore prior metadata from /etc/lvm/backup if data loss is detected.

Prevention & Hardening

Maintain VG metadata backups outside the affected host.

Linked to mdraid degradation and disk firmware failures.
