[LU-7474] Using lnet init script and lnetctl brings up tcp interface

Duplicate — Fri, 4 Dec 2015 23:53:52 +0000

We're attempting to migrate to lnetctl for some of our setup rather than using the lnet modprobe.conf file.

We removed the ip2nets parameter from the conf, and generated our /etc/sysconfig/lnet.conf file. Using the following method works (from an unconfigured system):

modprobe lnet
lnetctl lnet configure
lnetctl import < /etc/sysconfig/lnet.conf

The problem we're seeing is that the LNET init script calls lctl network up, which configures a default nid on the tcp interface (instead of the InfiniBand interface).

Is this indented behavior? Currently, we're planning to use the following in our LNET init script instead:

125,129c125
<       if [ -f $LUSTRE_LNET_CONFIG_UTILITY ] && [ -f "$LUSTRE_LNET_CONFIG_FILE" ]; then
<                 $LUSTRE_LNET_CONFIG_UTILITY lnet configure || exit 1
<         else
<                 lctl network up || exit 1
<         fi
---
>       lctl network up || exit 1

Thanks!
