Mounting and unmounting Lustre file systems on client nodes4–14

4.8 Alternative sfsmount modes

In addition to supporting the standard mount command with the lnet: protocol (as described in

Section 4.4), the sfsmount command also supports the following mount modes:

• The standard mount command with the http: protocol. (see Section 4.8.1).

• The lconf command with the ldap: protocol (see Section 4.8.2).

Support for the ldap: protocol is provided for backward compatibility; however, the ldap: protocol

will not be supported in the next major release of the HP SFS software—only the lnet: and http:

protocols will be supported.

4.8.1 Mounting Lustre file systems using the sfsmount command with the http:

protocol

NOTE: Lustre file systems must be mounted as root user, and the environment—in particular the PATH—

must be that of root. Do not use the su syntax when when changing to root user; instead, use the

following syntax:

su -

The sfsmount command supports the standard mount command with the http: protocol. To use the

http: protocol, the client node must have access to the HP SFS servers over a TCP/IP network.

NOTE: The http: mount protocol is intended to provide a convenient way to mount a file system without

having to specify complex lnet: options. However, it is not intended for use in systems where more than

32 client nodes may be mounting a file system at the same time (for example, when the client nodes are

booted).

The syntax of the sfsmount command using the http: protocol is as follows:

sfsmount [http://]system_name/filesystem [/mountpoint] [-o options]

Where:

http://

Is an optional prefix.

system_name

Is any name or IP address that resolves to an alias on the HP SFS system.

filesystem

Is the name of the Lustre file system that is to be mounted.

mountpoint

A local directory where the file system is to be mounted.

See Section 4.5 for information on the options that can be used with the sfsmount command.
