Symptom & Impact

Boot stalls at remote-fs target, delaying service availability and orchestration.

Environment & Reproduction

Seen when NFS servers are slow or unreachable during host startup.

Root Cause Analysis

Blocking /etc/fstab NFS entries wait indefinitely before timeout conditions are met.

Quick Triage

Inspect failed mount units and dependency chain in boot journal.

sudo journalctl -b -u remote-fs.target

Step-by-Step Diagnosis

Check fstab mount options and verify NFS server/network path readiness.

Solution – Primary Fix

Use systemd automount with nofail and bounded timeout options for NFS entries.

Solution – Alternative Approaches

Mount on-demand from application units or move critical startup data to local storage.

Verification & Acceptance Criteria

Boot reaches multi-user target quickly and NFS mounts activate on first access.

Rollback Plan

Restore prior fstab entry and original mount unit behavior if application requires eager mount.

Prevention & Hardening

Define remote filesystem standards and test server outage behavior in DR drills.
