NAME
     cachefsd - CacheFS daemon

SYNOPSIS
     /usr/lib/fs/cachefs/cachefsd


DESCRIPTION
     The  cachefsd  server  implements  features  of  the   cache
     filesystem  (CacheFS). It is invoked at boot time and run if
     the / (root) and /usr filesystems are being cached. If  /usr
     is  being  cached,  cachefsd  is  invoked  by inetd(1M) from
     inetd.conf(4). At run time, cachefsd is invoked by the inetd
     mechanism  in response to an RPC request from a user command
     such as mountcachefs(1M).


     The cachefsd server  supports  the  "disconnected  mode"  of
     CacheFS.  In  this  mode,  a  user can continue to read and,
     depending on the option selected, write to files in a cached
     filesystem  when  the NFS server for the cached files is not
     available.


     The cachefsd daemon performs the following functions in sup-
     port of the CacheFS:

         o    Implements the connection policy. The daemon deter-
              mines  whether  the NFS server backing the cache is
              connected or disconnected from the cache, or is  in
              transition   from  the  connected  or  disconnected
              states.

         o    Implements "log rolling," wherein the daemon  moni-
              tors  a  disconnected  NFS server for reconnection.
              After such a server returns to a  connected  state,
              cachefsd  rolls  any  local changes to cached files
              (kept in a log) back to the server.

         o    Manages "packing," wherein cachefsd  makes  a  best
              effort  to  ensure  that  files in a user-specified
              list are available in  the  cache  in  disconnected
              mode.

         o    Supports user interfaces by  supplying  statistics,
              reporting  conflicts between the cache and the back
              filesystem, and supporting  a  list  of  files  for
              packing.


     The running of cachefsd is  required  for  the  disconnected
     mode of CacheFS.
