VFS_MEDIA_HARMONY(8)					    System Administration tools 				      VFS_MEDIA_HARMONY(8)

NAME

       vfs_media_harmony - Allow multiple Avid clients to share a network drive.

SYNOPSIS

       vfs objects = media_harmony

DESCRIPTION

       This VFS module is part of the samba(7) suite.

       The vfs_media_harmony VFS module allows Avid editorial workstations to share a network drive. It does this by:

	1. Giving each client their own copy of the Avid msmMMOB.mdb and msmFMID.pmr files and Creating directories.

	2. Allowing each client to explicitly control the write time the Avid application sees on Avid media directories.

       This module is stackable.

CONFIGURATION

       vfs_media_harmony automatically redirects requests from clients for Avid database files or an Avid Creating directory to a client-specific
       version of the file. No configuration beyond enabling the module is needed to get this portion of its functionality working.

       If Mac and Windows Avid clients will be accessing the same folder, they should be given separate share definitions, with hidden Mac files
       vetoed on the Windows share. See EXAMPLES.

       To allow each client to control when the Avid application refreshes their Avid databases, create files for each client and each Avid media
       directory with the name [avid_dir_name]_[client_ip_address]_[client_username]. To trigger Avid database refreshes, update the write time on
       those files. See EXAMPLES.

       It is also necessary for the cache locked write times = no option to be set for clients to be able to control their Avid media folder write
       times.

EXAMPLES

       Enable media_harmony for Mac and Windows clients:

		   [avid_mac]
		path = /avid
		vfs objects = media_harmony
		cache locked write times = no
		   [avid_win]
		path = /avid
		vfs objects = media_harmony
		cache locked write times = no
		veto files = /.DS_Store/._@/.Trash@/.Spotlight@/.hidden/.hotfiles@/.vol/
		delete veto files = yes

       Create the files that will allow users david and susan to control their own Avid database refreshes:

		touch '/avid/OMFI MediaFiles_192.168.1.10_david' 
		     '/avid/OMFI MediaFiles_192.168.1.11_susan' 
		     '/avid/Avid MediaFiles/MXF/1_192.168.1.10_david' 
		     '/avid/Avid MediaFiles/MXF/1_192.168.1.11_susan'

       Trigger an Avid database refresh for user david:

		touch '/avid/OMFI MediaFiles_192.168.1.10_david' 
		     '/avid/Avid MediaFiles/MXF/1_192.168.1.10_david'

       If you have a large number of Avid media folders to manage, you can give each editor a suitably modified version of
       examples/scripts/vfs/media_harmony/trigger_avid_update.py to create and update these files.

CAVEATS

       vfs_media_harmony is designed to work with Avid editing applications that look in the Avid MediaFiles or OMFI MediaFiles directories for
       media. It is not designed to work as expected in all circumstances for general use. For example: It is possible to open a client-specific
       file such as msmMMOB.mdb_192.168.1.10_userx even though it doesn't show up in a directory listing.

NAME

       vfs_readahead - pre-load the kernel buffer cache

SYNOPSIS

       vfs objects = readahead

DESCRIPTION

       This VFS module is part of the samba(7) suite.

       This vfs_readahead VFS module detects read requests at multiples of a given offset (hex 0x80000 by default) and then tells the kernel via
       either the readahead system call (on Linux) or the posix_fadvise system call to pre-fetch this data into the buffer cache.

       This module is useful for Windows Vista clients reading data using the Windows Explorer program, which asynchronously does multiple file
       read requests at offset boundaries of 0x80000 bytes.

       The offset multiple used is given by the readahead:offset option, which defaults to 0x80000.

       The size of the disk read operations performed by vfs_readahead is determined by the readahead:length option. By default this is set to the
       same value as the readahead:offset option and if not set explicitly will use the current value of readahead:offset.

       This module is stackable.

OPTIONS

       readahead:offset = BYTES
	   The offset multiple that causes readahead to be requested of the kernel buffer cache.

       readahead:length = BYTES
	   The number of bytes requested to be read into the kernel buffer cache on each readahead call.

       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

		[hypothetical]
		vfs objects = readahead

       This man page is correct for version 3.0.25 of the Samba suite.
