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

21 The cachefsd server supports the "disconnected mode" of CacheFS. In
22 this mode, a user can continue to read and, depending on the option
23 selected, write to files in a cached filesystem when the NFS server for
24 the cached files is not available.
25
26
27 The cachefsd daemon performs the following functions in support of the
28 CacheFS:
29
30 o Implements the connection policy. The daemon determines
31 whether the NFS server backing the cache is connected or
32 disconnected from the cache, or is in transition from the
33 connected or disconnected states.
34
35 o Implements "log rolling," wherein the daemon monitors a dis‐
36 connected NFS server for reconnection. After such a server
37 returns to a connected state, cachefsd rolls any local
38 changes to cached files (kept in a log) back to the server.
39
40 o Manages "packing," wherein cachefsd makes a best effort to
41 ensure that files in a user-specified list are available in
42 the cache in disconnected mode.
43
44 o Supports user interfaces by supplying statistics, reporting
45 conflicts between the cache and the back filesystem, and
46 supporting a list of files for packing.

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

53 The following options are supported:
