Symptom & Impact

NVMe namespace lost after firmware update on CentOS Stream 9 disrupts services and slows incident response until the root cause is resolved.

Environment & Reproduction

Namespace disappears after vendor firmware upgrade because controller renumbers namespaces.

nvme list
lsblk
dmesg | grep -i nvme

Root Cause Analysis

Misalignment between storage configuration and CentOS Stream 9 defaults causes the failure path described above.

Quick Triage

Confirm package state, service status, and recent changes before deeper diagnostics.

systemctl status
rpm -qa | grep -i 
journalctl -p err -b --no-pager | tail -100

Step-by-Step Diagnosis

Capture detailed logs, configuration deltas, and runtime state to isolate the failing component.

nvme id-ctrl /dev/nvme0
nvme list-ns /dev/nvme0
journalctl -k | grep nvme

Solution – Primary Fix

Apply the targeted configuration change and restart the relevant services to restore expected behavior.

sudo nvme ns-rescan /dev/nvme0
sudo udevadm trigger
sudo systemctl restart multipathd

Solution – Alternative Approaches

Use /dev/disk/by-id paths in fstab to survive namespace renumbering.

Verification & Acceptance Criteria

Validate the fix with deterministic checks and ensure no regressions in dependent services.

nvme list
blkid

Rollback Plan

Revert configuration and restart services to return to the previous known-good state.

sudo nvme firmware-activate /dev/nvme0 -s 0
reboot

Prevention & Hardening

Stage firmware updates and validate /dev/disk/by-id mapping post-update.
