Symptom & Impact
Critical mount points fail during boot, preventing dependent services from starting.
Environment & Reproduction
Often triggered by initramfs omissions, renamed PVs, or delayed storage attachment.
Root Cause Analysis
Volume group metadata is present but not auto-activated in early boot sequence.
Quick Triage
Check LVM visibility and whether vgchange can activate manually.
Step-by-Step Diagnosis
Inspect initramfs contents and lvm.conf activation filters for unintended exclusions.
Solution – Primary Fix
Activate VG, repair config, and regenerate initramfs and GRUB metadata.

Solution – Alternative Approaches
Use UUID-based fstab and delayed mount units for slow SAN attachment environments.
Verification & Acceptance Criteria
All LVs activate at boot and expected filesystems mount automatically.
Rollback Plan
Revert lvm.conf filter changes and boot with previous initramfs image.
Prevention & Hardening
Document storage topology and continuously test reboot behavior after storage policy changes.
