Modifying the /etc/modules.conf file on Linux Version 2.4 client nodes manually B–7

4. To configure the options lnet settings on the client node, add an entry to the

/etc/modules.conf.lustre file to specify the networks that are to be used to connect to the

HP SFS system. Use the following syntax:

options lnet option1=value1 [option2=value2...]

The syntax of the supported options is as follows:

networks=network1[,network2...]

portals_compatibility=weak|none

When listing the networks, put the fastest interconnect first in the networks option list; this ensures

that the fastest interconnect will be used (where possible) for file system I/O operations.

The following example shows the entry for a system that uses a Gigabit Ethernet interconnect and a

Myrinet interconnect. In this example, none of the servers that the client will access are running in

Portals compatibility mode:

options lnet networks=gm0,tcp0(eth1) portals_compatibility=none

See Section B.2 for more examples.

5. To enable the client node to use quotas functionality, add the following lines to the

/etc/modules.conf.lustre file:

add below lov lquota

add below mdc lquota

add below osc lquota

post-remove mdc /sbin/modprobe -r lquota
