cfs – cache file system|
cfs –s [–dknrS] [–f partition]
Cfs is a user–level file server that caches data from remote files
onto a local disk. It is normally started by the kernel at boot
time, though users may start it manually. Cfs is interposed between
the kernel and a network connection to a remote file server to
improve the efficiency of access across slow network
connections such as modem lines. On each open of a file cfs checks
the consistency of cached information and discards any old information
for that file.
n mount the remote file server without authentication; often useful with –F.
r reformat the cache disk partition.
s the connection to the remote file server is on file descriptors 0 and 1.
S turn on statistics gathering. A file called cfsctl at the root of the caching file system can be read to get statistics concerning number of calls/bytes on client and server sides and latencies.
