NAME

6       cachefsd - CacheFS daemon
7

SYNOPSIS

9       /usr/lib/fs/cachefs/cachefsd
10
11

DESCRIPTION

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).
19
20
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.
47
48
49       The running of cachefsd  is  required  for  the  disconnected  mode  of
50       CacheFS.
