## CacheItems

Purpose

Records information about each V n file in a disk cache

Description

The CacheItems file records information about each file in the disk cache on a client machine (each V n file). The information includes the file ID number and associated volume version number of the AFS file currently stored in the V n file, which enables the Cache Manager to determine which V n file contains the AFS data it needs to present to an application.

As it initializes, the Cache Manager creates the binary-format CacheItems file in the same local disk cache directory as the V n files that the CacheItems file describes, and it must always remain there. The conventional directory name is /usr/vice/cache, but it is acceptable to use a directory on a partition with more available space.

Cautions

Editing or removing the CacheItems file can cause a kernel panic. If the contents of V n files seem out of date, clear the files by using the fs flush or fs flushvolume command. If the CacheItems file is accidentally modified or deleted, rebooting the machine usually restores normal performance.
