[LU-10118] exec start error for lustre-2.10.1_13_g2ee62fb

Duplicate — Fri, 13 Oct 2017 22:46:53 +0000

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:

The fix for this was:
Google suggests that this error message has been associated with a missing “hashpling” in some cases. The lustre_routes_config script has “# Unable to render embedded object: File (/bin/bash”, and I wonder if that space before the “) not found.” 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.
