New Features in CacheFS

Cachefspack

The cachefspack command improves CacheFS performance and allows greater control over the cache contents, because it ensures that the specified files are always present in the cache.

This command enables you to pre-load specific files and directories in the cache. The functionality provided by this command is comparable to the rpages option.

Supports Large Files and File Systems

CacheFS supports the maximum file and filesystem sizes supported by the underlying front filesystem in which the cache resides.

CacheFS data structures are 64-bit compliant.

Enhanced Cache Consistency Checking

Consistency checking on demand, demandconst, is fully implemented. However, consistency is not checked at file open time.

Mount options can be switched without deleting or rebuilding the cache.

New Consistency option

The new consistency option, weakconst, verifies the consistency of the cache with the NFS client copy of file attributes, and delays committing the changes to the server. This improves the CacheFS response time.

Enhanced Error Messages

Provides enhanced error messages that display the command name. Error messages are now printed to standard error, instead of standard output. This makes troubleshooting easier.
