vfs_acl_xattr(8) [centos man page]

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). This module is stackable. OPTIONS
acl_xattr:ignore system acls = [yes|no] When set to yes, a best effort mapping from/to the POSIX ACL layer will not be done by this module. The default is no, which means that Samba keeps setting and evaluating both the system ACLs and the NT ACLs. This is better if you need your system ACLs be set for local or NFS file access, too. If you only access the data via Samba you might set this to yes to achieve better NT ACL compatibility. AUTHOR

NAME
vfs_aio_fork - implement async I/O in Samba vfs SYNOPSIS
vfs objects = aio_fork DESCRIPTION
This VFS module is part of the samba(7) suite. The aio_fork VFS module enables async I/O for Samba on platforms where the system level Posix AIO interface is insufficient. Posix AIO can suffer from severe limitations. For example, on some Linux versions the real-time signals that it uses are broken under heavy load. Other systems only allow AIO when special kernel modules are loaded or only allow a certain system-wide amount of async requests being scheduled. Systems based on glibc (most Linux systems) only allow a single outstanding request per file descriptor. To work around all these limitations, the aio_fork module was written. It uses forked helper processes instead of the internal Posix AIO interface to create asynchronousity for read and write calls. It has no parameters, it will create helper processes when async requests come in as needed. Idle helper processes will be removed every 30 seconds. This module is stackable. EXAMPLES
Straight forward use: [cooldata] path = /data/ice vfs objects = aio_fork VERSION
This man page is correct for version 4.0.0 of the Samba suite. AUTHOR
