<html><body><p>Matt, GPFS version 4.1.0-8 and prior had an issue with RHEL 7.1 systemd. Red Hat introduced new changes is systemd that led to this issue. Subsequently Red Hat issued an errata and reverted the changes to systemd (<a href="https://rhn.redhat.com/errata/RHBA-2015-0738.html">https://rhn.redhat.com/errata/RHBA-2015-0738.html</a>).
