Symptom & Impact

Volume group activation fails because a physical volume is not found.

Environment & Reproduction

Triggered by HBA changes, multipath drift, or removed iSCSI sessions.

Root Cause Analysis

PV UUID is unavailable, causing the VG to remain partial or inactive.

Quick Triage

Run pvs, vgs, and lvs to identify missing PV UUIDs.

Step-by-Step Diagnosis

Check dmesg and multipath -ll for storage path failures.

Solution – Primary Fix

Restore path or replace PV with vgreduce –removemissing then vgextend.

Solution – Alternative Approaches

Activate VG partially with vgchange -ay –partial for emergency reads.

Verification & Acceptance Criteria

All LVs activate cleanly on boot without –partial flag.

Rollback Plan

Reverse vgreduce by re-importing the missing PV when path returns.

Prevention & Hardening

Document and test storage zoning and multipath maps regularly.

Related Errors & Cross-Refs

Related to dm-multipath and udev rule misconfigurations.
