Alternative sfsmount modes 4–15

4.8.2 Mounting Lustre file systems using the sfsmount command with the ldap:

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 -

NOTE: The network or networks that a client node can use to access the HP SFS system may or may not be

configured with an alias IP address. If an alias IP address is not configured on a network that client nodes

use to access the HP SFS system, mount instructions using the ldap: protocol must specify the names of the

first and second servers in the HP SFS system (that is, the administration and MDS servers) rather than the

HP SFS system name.

For backward compatibility with earlier versions of the HP SFS software, the sfsmount command currently

supports the lconf command with the ldap: protocol. Note, however, that 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.

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

sfsmount ldap://system_name|serverlist/filesystem [/mountpoint] [-o options]

Where:

ldap://

Is a required prefix for mounts using the ldap: protocol.

system_name|serverlist

Specifies the HP SFS system where the Lustre file system is located. This field is used to access an

LDAP server that contains configuration data for the file system.

If this field contains a system name (that is, contains a single name), this name must resolve to an

alias IP address on a network in the HP SFS system. Alias IP addresses are (optionally)

configured on networks in the HP SFS system, and are served by the HP SFS server that is

running the administration service. If this service fails over to a backup server, the alias also fails

over to the backup server.

If this field contains a list of servers, the names of both the administration and MDS servers in the

HP SFS system must be specified. The sfsmount command attempts to get configuration data

from the first server specified. If the attempt fails, the command then attempts to get the

configuration data from the second server. This functionality allows client nodes to access the

server where the administration service is running on a network that does not have an alias

configured; this could be a Gigabit Ethernet network or an InfiniBand interconnect.

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.
