Lustre 1.6 Operations Manual

CHAPTER 31
Configuration Files and Module
Parameters (man5)
This section describes configuration files and module parameters and includes the
following sections:
■ Introduction
■ Module Options
31.1 Introduction
LNET network hardware and routing are now configured via module parameters.
Parameters should be specified in the /etc/modprobe.conf file, for example:
alias lustre llite
options lnet networks=tcp0,elan0
The above option specifies that this node should use all the available TCP and Elan
interfaces.
Module parameters are read when the module is first loaded. Type-specific LND
modules (for instance, ksocklnd) are loaded automatically by the LNET module
when LNET starts (typically upon modprobe ptlrpc).
Under Linux 2.6, LNET configuration parameters can be viewed under
/sys/module/; generic and acceptor parameters under LNET, and LND-specific
parameters under the name of the corresponding LND.
Under Linux 2.4, sysfs is not available, but the LND-specific parameters are
accessible via equivalent paths under /proc.
