Mounting and unmounting Lustre file systems on client nodes4–6

[no]repeat sfsmount Specifies whether repeated attempts are to be made to

mount the file system (until the mount operation succeeds),

or if only one attempt is to be made to mount the file system.

When the sfsmount command is run interactively, the

default for this option is norepeat. When the sfsmount

command is used by the SFS service, the SFS service adds

the repeat mount option unless the /etc/sfstab or

/etc/sfstab.proto file specifies norepeat.

To reduce the possibility of the mount operation failing as a

result of the mount command timing out before the server

has had time to respond, HP recommends that you do not

specify the norepeat option in the /etc/sfstab or

/etc/sfstab.proto file.

[no]auto mount and sfsmount Specifies whether the file system is to be automatically

mounted at boot time. The default is auto (that is, the file

system is to be automatically mounted at boot time).

With the mount command, this option is used in directives

in the /etc/fstab file. With the sfsmount command,

the option is used in directives in the /etc/sfstab and

/etc/sfstab.proto files.

verbose sfsmount Invokes the lconf command with the --verbose option.

net=value[n] sfsmount This option is ignored by the sfsmount command. The

functionality of the option has been superseded by the use

of an appropriate options lnet setting in the

/etc/modprobe.conf.lustre or

/etc/modules.conf.lustre configuration file.

nal=value[n] sfsmount Same as the net option.

max_cached_mb=value sfsmount Specifies how much client-side cache space is to be used for

a file system.

max_dirty_mb=value sfsmount Specifies how much dirty data can be created on a client

node for each OST service. The default value of this

parameter is 32 (that is, 32MB).

max_rpcs_in_flight=

value

sfsmount Specifies the number of simultaneous RPCs that can be

outstanding to a server. If the max_dirty_mb option is

specified, the max_rpcs_in_flight option must have

the same value.

xxxxxxx sfsmount For mount operations using the lnet: or http: protocols,

passes the options unchanged to the mount command.

For mounts using the ldap: protocol, invokes the lconf or

sfslconf command with the --xxxxxxx option (where

xxxxxxx is any valid lconf option without an argument).

xxxxxxx=yyyyyyy sfsmount For mount operations using the lnet: or http: protocols,

passes the options unchanged to the mount command.

For mounts using the ldap: protocol, invokes the lconf or

sfslconf command with the --xxxxxxx yyyyyyy

option pair (where xxxxxxx is any valid lconf option

with a single argument).

server=name N/A Specifies the name of the HP SFS server on the external

network. This option is ignored by the sfsmount

command. It is good practice to use the fs option when

using the lnet: protocol; the option allows the

sfsconfig command to locate the appropriate HP SFS

server. See Appendix A for a description of the sfsconfig

command.
