cachefslog(1M)cachefslog(1M)NAMEcachefslog - Cache File System logging
The command is used to enable or disable logging for a
cachefs_mount_point. When the command is used without any options, it
displays the logfile. The logfile contains information on the opera‐
tion performed on a cachefs_mount_point and statistics used by to get
the working set size of cache directory. The specified logfile will
contain information for all the CacheFS mount points using the same
cache directory. A logfile and a cache directory have a 1-to-1 map‐
ping; that is, even if a cache directory is removed and recreated with
the same name, the logfile used in the previous instance of the cache
directory cannot be reused with the new cache directory.
Enabling logging may have performance impact, even if minimal, on the
operations for all the CacheFS mount points using the same cache direc‐
tory. The command is mainly used for debugging purposes.
The following options are supported. You must be a superuser to use
