ing process.
Options
To mount a CacheFS file system, use the generic
argument
. The following generic
cachefs
-e
Verbose mode. Write a message to the standard output indicating which file system is
being mounted.
Mount the file system read-only.
-r
The following arguments to the
multiple options. Notice that the
file_system_type
backfstype=
The file system type of the back file system (for example,
path
backpath=
Specifies where the back file system is already mounted. If this argument is not supplied,
CacheFS determines a mount point for the back file system. The back file system must be
read-only.
directory
cachedir=
The name of the cache directory.
ID ID is a string specifying a particular instance of a cache. If you do not specify a cache ID,
cacheid=
CacheFS will construct one.
If specified when mounting a CacheFS file system, a binary will be read and populated in
rpages
the cache the first time it is loaded. Subsequent access to the binary will be satisfied from
the cache.

write-around
non-shared
Write modes for CacheFS. The
same as NFS does; that is, writes are made to the back file system, and the affected file is
purged from the cache. You can use the
one else will be writing to the cached file system. In this mode, all writes are made to both
the front and the back file system, and the file remains in the cache.
noconst
Disables cache consistency checking. By default, periodic consistency checking is enabled.
Specify
ing to perform cache consistency check using
demandconst
demandconst
Verifies cache consistency only when explicitly requested, rather than the periodic checking
that is done by default. A consistency check is requested by using the
cfsadmin(1M) command. This option is useful for back file systems that change infre-
quently, for example,
local-access
Causes the front file system to interpret the mode bits used for access checking instead or
having the back file system verify access permissions. Do not use this argument with secure
NFS .
purge
Purge any cached information for the specified file system.
rw

ro
Read-write (default) or read-only.
