cachefsd(1M) System Administration Commands cachefsd(1M)NAMEcachefsd - 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 mount_cachefs(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 support of the
CacheFS:
o Implements the connection policy. The daemon determines
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 monitors a dis‐
connected 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.
OPTIONS
The following options are supported:
