<P>Records information about each <B>V</B><VAR>n</VAR> file in a disk cache
|
|
<P><STRONG>Description</STRONG>
|
|
<P>The <B>CacheItems</B> file records information about each file in the
|
|
disk cache on a client machine (each <B>V</B><VAR>n</VAR> file). The
|
|
information includes the file ID number and associated volume version number
|
|
of the AFS file currently stored in the <B>V</B><VAR>n</VAR> file, which
|
|
enables the Cache Manager to determine which <B>V</B><VAR>n</VAR> file
|
|
contains the AFS data it needs to present to an application.
|
|
<P>As it initializes, the Cache Manager creates the binary-format
|
|
<B>CacheItems</B> file in the same local disk cache directory as the
|
|
<B>V</B><VAR>n</VAR> files that the <B>CacheItems</B> file describes,
|
|
and it must always remain there. The conventional directory name is
|
|
<B>/usr/vice/cache</B>, but it is acceptable to use a directory on a
|
|
partition with more available space.
|
|
<P><STRONG>Cautions</STRONG>
|
|
<P>Editing or removing the <B>CacheItems</B> file can cause a kernel
|
|
panic. If the contents of <B>V</B><VAR>n</VAR> files seem out of
|
|
date, clear the files by using the <B>fs flush</B> or <B>fs
|
|
flushvolume</B> command. If the <B>CacheItems</B> file is
|
|
accidentally modified or deleted, rebooting the machine usually restores
|
|
normal performance.
