+ <citerefentry><refentrytitle>samba</refentrytitle>
+ <manvolnum>7</manvolnum></citerefentry> suite.</para>
+
+ <para>The <command>tsmsm</command> VFS module is an
+ extension for handling offline files with Tivoli
+ Storage Manager Space Management.
+ </para>
+
+ <para>
+ It tries to avoid calling expensive DMAPI calls with some
+ heuristics based on the fact that number of blocks reported of a
+ file multiplied by 512 will be bigger than 'online ratio' of
+ actual size for online (non-migrated) files.
+ If heuristic check fails, the module calls DMAPI and asks for
+ a specific attribute which is present for offline (migrated)
files.
+ If this attribute presents, the file is considered offline.
+ </para>
+
+ <para>This module is not stackable.</para>
