Symptom & Impact

Boot enters degraded state and dependent services fail because NFS paths are unavailable.

Environment & Reproduction

RHEL 7 host with static fstab NFS mount boots before network or rpcbind is fully ready.

Root Cause Analysis

Mount options lack _netdev and nofail handling, causing early boot timeout and service dependency collapse.

Quick Triage

Inspect systemctl –failed, check journalctl for mount timeouts, and validate NFS server reachability.

Step-by-Step Diagnosis

Test manual mount, verify rpcbind and nfs-client target state, and inspect fstab option correctness.

Solution – Primary Fix

Add _netdev,nofail,x-systemd.automount options, reload daemon, and restart remote-fs target.

Solution – Alternative Approaches

Replace static fstab with autofs for dynamic mounts when network readiness is variable.

Verification & Acceptance Criteria

System boots cleanly, NFS path appears on access, and dependent service starts without delay.

Rollback Plan

Restore previous fstab entry and disable automount if application behavior requires immediate static mounts.

Prevention & Hardening

Standardize NFS mount templates and include boot dependency tests after storage or network changes.

Related Errors & Cross-Refs

Can overlap with firewalld port restrictions and SELinux context issues on mounted paths.
