lustre_routes_config(8)

NAME

lustre_routes_config - Configure routes dynamically

SYNOPSIS

DESCRIPTION

lustre_routes_config sets or cleans up LNET routes from the specified config file. /etc/lnet_routes.conf file can be used to automatically configure routes on LNET startup.

The format of the config file is:

OPTIONS

--setup

Configure routes listed in config_file

--cleanup

Unconfigure routes listed in config_file

--dry-run

Echo commands to be run, but do not execute them

--verbose

Echo commands before they are executed

FILES

/etc/lnet_routes.conf

NOTES

An LNET router is identified when its local NID appears within the list of routes. However, this can not be achieved by the use of this script, since the script only adds extra routes after the role of the router is determined. To ensure that a router is identified correctly, make sure to add its local NID in the routes parameter in the modprobe lustre configuration file.

EXAMPLES

An example of a config file that the script expects:

tcp1: { gateway: 10.1.1.2@tcp0, priority: 3 }
tcp4: { gateway: 10.3.3.4@tcp }
tcp6: { gateway: 10.3.3.6@tcp, hop: 2, priority: 5 }
tcp7: { gateway: 10.3.3.[6-12]@tcp, priority: 20, hop: 8 }

An example of script execution:

lustre_routes_config --setup <path/to/routes_config_file>
lustre_routes_config --cleanup <path/to/routes_config_file>
