4.5 Mount options

Table 4-1 describes the options that can be specified in the -o option list with the mount command

and/or the sfsmount command for Lustre file systems. Some of the options are processed by the

sfsmount command; some are processed by the SFS service (as described in Section 4.7); others are

processed by the sfsconfig command only (see Appendix A for more information).

Table 4-1 Mount options

Name mount and/or sfsmount Description

lconf|sfslconf sfsmount Specifies whether the lconf command or the sfslconf

command is to be used for the mount operation. The lconf

command is used by default when the sfsmount

command is used with the ldap: protocol.

The sfslconf command has been deprecated since

HP SFS Version 2.0.

acl mount and sfsmount Specifies whether access control lists (ACLs) are to be used

with the mount point. If ACLs are to be used, they must be

enabled on the Lustre file system.

user_xattr mount and sfsmount Specifies whether extended attributes are to be used with

the mount point. If extended attributes are to be used, they

must be enabled on the Lustre file system.

usrquota mount and sfsmount Enables user quotas. If quotas are to be used, the quota

functionality must be enabled on the Lustre file system.

grpquota mount and sfsmount Enables group quotas. If quotas are to be used, the quota

functionality must be enabled on the Lustre file system.

/jointfilesconvert/261981/bg[=N] sfsmount Specifies that the file system is to be mounted in the

background after a timeout of N seconds. If you do not

specify that the file system is to be mounted in the

background, it will be mounted in the foreground.

If you specify the /jointfilesconvert/261981/bg option without specifying a number of

seconds, the default timeout is 30 seconds.

fg sfsmount Specifies that the file system is to be mounted in the

foreground. This is the default behavior (unless you specify

the /jointfilesconvert/261981/bg option).

onmount=script sfsmount Specifies a script that will be run after the mount operation

has completed. This option is useful in conjunction with

background mount operations.
