The CacheInfo file, which is manually created during DFS client installation, is composed of three fields separated by colons: the first field specifies where the DCE global namespace is mounted; the second field names the cache directory where the Cache Manager creates its cache files; and the third field specifies the cache size in 1024-byte (1-kilobyte) blocks.
The Cache Manager creates and maintains the following files, which are not intended for direct use. You can cause the kernel to panic if you accidentally modify any of these files; if this happens, rebooting the machine should restore normal performance. Note that these files exist only on client machines that use disk caching; a machine that uses a memory cache maintains in memory the cache information the files contain.
Caution: Never directly modify or delete these files; this can cause the kernel to panic. Always use the commands provided with DFS to alter these files.
· Multiple dcelocal/var/adm/dfs/cache/Vn files, where n is a unique number for each file. By default, each Vn file holds up to 64 kilobytes of a cached file; files larger than 64 kilobytes are divided into multiple files. The number of Vn files, or V files, depends on the cache size.
· The dcelocal/var/adm/dfs/cache/CacheItems file. The Cache Manager uses this binary file to record information about each V file, including its file ID number and data version number.
· The dcelocal/var/adm/dfs/cache/FilesetItems file. This binary file stores the fileset-to-mount point mapping for each fileset accessed. This mapping enables the Cache Manager to respond correctly to commands such as pwd.
