Google suggests that this error message has been associated with a missing “hashpling” in some cases. The lustre_routes_config script has “# !/bin/bash”, and I wonder if that space before the “!” isn’t the culprit?

Just a guess. You might try to remove that space from the lustre_routes_config script and try to restart lnet with systemctl.

    Greetings,
    
    I have built lustre-2.10.1_13_g2ee62fb on 3.10.0-693.2.2.el7.x86_64 RHEL Workstation release 7.4 (Maipo).
    
    After installation of kmod-lustre-client-2.10.1_13_g2ee62fb-1.el7.x86_64.rpm and lustre-client-2.10.1_13_g2ee62fb-1.el7.x86_64.rpm the lnet startup fails. 
    
    The error reported is:
