How to Delete a CacheFS File System

1. Become superuser on the client system.

2. Unmount the CacheFS file system.

   # umount /mount-point

   /mount-point specifies the CacheFS file system that you want to delete.

3. Determine the name of the CacheFS file system (cache ID).

   # cfsadmin -l /cache-directory cfsadmin: list cache FS information maxblocks 90% minblocks 0% threshblocks 85% maxfiles 90% minfiles 0% threshfiles 85% maxfilesize 3MB cache-ID #

4. Delete the CacheFS file system from the specified cache.

   # cfsadmin -d cache-ID /cache-directory

   cache-ID	Indicates the name of the CacheFS file system, which is the last line of the cfsadmin -l output. For more information, see How to Display Information About a CacheFS File System. You can delete all the CacheFS file systems in a particular cache by specifying all for cache-ID.
   /cache-directory	Specifies the directory where the cache resides.

5. Verify that the file system has been deleted.

   The cache ID of the file system you just deleted should be missing from the cfsadmin -l output.

   # cfsadmin -l /cache-directory cfsadmin: list cache FS information maxblocks 90% minblocks 0% threshblocks 85% maxfiles 90% minfiles 0% threshfiles 85% maxfilesize 3MB #

   For more information about the fields that are specified in the command output, refer to cfsadmin(1M).

6. Update the resource counts for the cache by running the fsck -F cachefs command.

   For more information, see How to Check the Integrity of a CacheFS File System.
