Using the sfsconfig commandA–2

The sfsconfig command also adds the lquota setting (which is needed to allow the client node to use

quotas functionality) in the /etc/modprobe.conf or /etc/modules.conf file.

The sfsconfig command also updates the file system mount directives in the /etc/sfstab and

/etc/sfstab.proto files.

The syntax of the sfsconfig command is as follows:

sfsconfig [options] [target]

Where the options are one or more of the following:

-X|--noexec Displays the changes that are needed; the changes are not performed if this

option is specified.

-H|--keephttp Specifies that the http: mount directives in the /etc/sfstab and /etc/

sfstab.proto files are to be preserved.

-L|--keepldap Specifies that the ldap: mount directives in the /etc/sfstab and /etc/

sfstab.proto files are to be preserved.

-a|--all Specifies that the command is to configure options lnet settings for all

networks detected on the client. The default is to configure settings only for

those networks that are detected as being needed.

Specifying the -a|--all option prevents the possibility of a network not

being configured because the sfsconfig command (mistakenly) assumes

that the network is not needed.

However, there is a drawback to using the -a|--all option; if the option is

specified, the sfsconfig command will configure all networks, including

slow internet access networks that are not to be used as interconnects, and

may cause the tcp lnet packets to be incorrectly routed.

HP recommends that you do not use the -a|--all option unless you have

detected a problem such as a network not being configured by the

sfsconfig command.

-s|--server name Adds a named HP SFS server to the list of servers that the client is to connect

to. (May be used more than once to specify more than one server.)

-u|--unload Specifies that the command is to attempt to unload lnet modules before

reconfiguring the /etc/modprobe.conf or /etc/modules.conf file.

Unloading the lnet modules ensures that the new settings will be used the

next time a Lustre file system is mounted on the node. If this option is not

used, the existing settings will still apply on the node, because modules only

read the /etc/modprobe.conf or /etc/modules.conf file when they

boot.

The --unload option may fail if there are applications using the lnet

modules on the client node. The sfsconfig command attempts to unmount

all mounted Lustre file systems before it unloads existing lnet modules.

If the --unload option fails, you must reboot the client node to bring the

new options lnet settings into effect.

-q|--quiet Specifies that the command is to run in quiet mode and will not ask for

confirmation of actions during processing.

-v|--verbose Displays verbose information.

-h|--help Displays help on the usage of the command.

-V|--version Displays the command version.
