New CacheFS Features in ONCplus B.11.31_LR
CacheFS supports the following features:
• Complete Binary Caching
CacheFS is commonly used to manage application binaries. This feature enables you to cache
a complete binary file in the local cache. To force a client to cache a complete copy of the
accessed binary file, use the rpages mount option. For more information on the rpages
mount option, see the NFS Services Administrator’s Guide.
• Cache Pre-Loading
This feature enables you to pre-load or pack specific files and directories in the cache. Packing
files and directories enables you to have greater control over the cache contents because it
ensures that the specified files are always present in the cache. Use the cachefspack
command to pack specific files and directories.
• Cache Administering
This feature enables you to perform administrative tasks, such as creation and deletion of a
cache directory. It also enables you to update the resource parameters of the specified cache
directory. In addition, you can view the contents and statistics of the cache.
• CacheFS Write Modes
CacheFS supports two write modes, write-around and non-shared. In the write-around
mode, writes are made to the back filesystem. Write-around mode is the default write
mode. In the non-shared mode, writes are made both to the front and the back filesystems.
• Cache Consistency Checking
CacheFS checks the files that are stored in the cache to ensure that the files are kept up to
date. With this version of CacheFS, the default behavior is that the consistency checking used
can impact CacheFS performance. Following are mount options that can be used to change
the type of consistency checking performed by CacheFS:
◦ noconst Disable consistency checking.
◦ demandconst Consistency checking is performed on demand.
◦ weakconst Consistency check used to verify cache consistency with the NFS client's
copy of the attributes. weakconst is the consistency checking level similar to the default
behavior in HP-UX 11i v2.
NOTE: Consistency is not checked at file open time.
