Symptom & Impact

Mount points backed by LVM are missing after reboot.

Environment & Reproduction

Run vgs, lvs, and systemctl status lvm2-monitor.

Root Cause Analysis

Check whether one VG is affected or all LVM-managed storage.

Quick Triage

VG not autoactivated due to filter settings or missing device discovery.

Step-by-Step Diagnosis

Rescan with pvscan –cache and validate lvm.conf device filters.

Solution – Primary Fix

Activate with vgchange -ay and correct persistent config.

Solution – Alternative Approaches

Ensure related mount units become active after activation.

Verification & Acceptance Criteria

Not usually network-related unless backing storage is iSCSI or multipath.

Rollback Plan

After manual mount recovery, confirm expected labels with restorecon.

Prevention & Hardening

Use journalctl -b for lvm2 and udev timing errors.

Related Errors & Cross-Refs

Keep stable device naming and validated lvm.conf filters.
