VFS_ACL_XATTR(8) System Administration tools VFS_ACL_XATTR(8)NAME
vfs_acl_xattr - Save NTFS-ACLs in Extended Attributes (EAs)
SYNOPSIS
vfs objects = acl_xattr
DESCRIPTION
This VFS module is part of the samba(7) suite.
The vfs_acl_xattr VFS module stores NTFS Access Control Lists (ACLs) in Extended Attributes (EAs). This enables the full mapping of Windows
ACLs on Samba servers.
The ACLs are stored in the Extended Attribute security.NTACL of a file or directory. This Attribute is not listed by getfattr -d filename.
To show the current value, the name of the EA must be specified (e.g. getfattr -n security.NTACL filename ).
Please note that this module is experimental!
This module is stackable.
OPTIONS
There are no options for vfs_acl_xattr.

vfs_prealloc - preallocate matching files to a predetermined size
SYNOPSIS
vfs objects = prealloc
DESCRIPTION
This VFS module is part of the samba(7) suite.
The vfs_prealloc VFS module preallocates files to a specified size each time a new file is created. This is useful in environments where
files are of a predetermined size will be written to a disk subsystem where extending file allocations is expensive.
This module is stackable.
OPTIONS
prealloc:EXT = BYTES
Preallocate all files with the extension EXT to the size specified by BYTES.
The following suffixes may be applied to BYTES:
o K - BYTES is a number of kilobytes
o M - BYTES is a number of megabytes
o G - BYTES is a number of gigabytes
EXAMPLES
A process writes TIFF files to a Samba share, and the is known these files will almost always be around 4 megabytes (4194304 bytes):
[frames]
path = /data/frames
vfs objects = prealloc
prealloc:tiff = 4M
CAVEATS
vfs_prealloc is not supported on all platforms and filesystems. Currently only XFS filesystems on Linux and IRIX are supported.
VERSION
This man page is correct for version 3.0.25 of the Samba suite.

Hi all,
I want to create a new user and grant him ONLY transfer files access to a specific directory where he can only upload and read the files. He should be restricted to this activity only.
