media_harmony VFS module: Add and build by default.
- Supersedes previous patch. - Added various fixes for fake mtime functionality. - Now requires lp_cache_locked_write_times patch (bug 8912). - Removed various xattr functions to comply with recent VFS changes. - Changed SMB_STRUCT_DIR to DIR and SMB_STRUCT_DIRENT to struct dirent to comply with recent VFS changes. - Added manpage. - Added sample trigger_avid_update.py script.

<title>DESCRIPTION</title>

<para>This VFS module is part of the

<manvolnum>7</manvolnum></citerefentry> suite.</para>
|
||||
|
||||
<para>The <command>vfs_media_harmony</command> VFS module allows
|
||||
Avid editorial workstations to share a network drive. It does
|
||||
this by:</para>

<orderedlist continuation="restarts" inheritnum="ignore" numeration="arabic">
|

<listitem><para>Giving each client their own copy of the Avid

msmMMOB.mdb and msmFMID.pmr files and Creating directories.</para></listitem>

|

<title>CONFIGURATION</title>
|
||||
|
||||
<para><command>vfs_media_harmony</command> 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.</para>
|
||||
|
||||
<para>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.</para>
|
||||
|
||||
<para>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.</para>
|
||||
|
||||
<para>It is also necessary for the <command>cache locked write times = no</command>
|
||||
option to be set for clients to be able to control their Avid
|
||||
media folder write times.</para>

<para>If you have a large number of Avid media folders to manage,

<para><command>vfs_media_harmony</command> 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.</para>
