Mounting and unmounting Lustre file systems on client nodes4–4

TIP: If the client node has access to the HP SFS system on a TCP/IP network, you can generate the correct

address to be used in the sfsmount command with the lnet: protocol by entering the sfsmount

command with the -X option and the http: protocol, as shown in the following example:

# sfsmount -X http://south/test /mnt/test

4.3 Mounting Lustre file systems using the mount command

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 -

You can use the standard mount(8) command to mount file systems manually. You must specify lustre as

the file system type.

See Section 4.5 for information on the mount options for Lustre file systems.

Examples

# mount -t lustre 3712584958@gm0,3712584935@gm0:/south-mds3/client_gm /mnt/data

-o acl,usrquota,grpquota

# mount -t lustre 35@elan0,34@elan0:/south-mds3/client_elan /usr/scratch

# mount -t lustre 10.0.128.2@vib0,10.0.128.1@vib0:/south-mds3/client_vib /data

4.4 The device field in the sfsmount and mount commands

The syntax of the device field in the sfsmount and mount commands is as follows:

mdsnodes:/mdsname[/profile]

Where:

mdsnodes

Is in the format address@network[,address@network]

address is the network ID (NID) of the MDS server in the HP SFS system (as shown by the

sfsview command on the client node or by the sfsmgr show server command on

the HP SFS server)

network is typeN (type is one of tcp, elan, gm, vib and N is the network instance

number—typically 0 (zero))

You can specify two entries; the address of the server where the MDS service normally runs (the

first entry), and the address of the backup server for the MDS service (the second entry).

For example:

35@elan0,33@elan0

mdsname

Is in the format system_name-mds_service

system_name is the HP SFS system name (or system nickname, if the nickname attribute is

specified on the system)
