关于Coda DFS 的配置文件问题

下面是配置文件，对他的参数设置有很多疑问
[root@localhost srv]# vi /etc/coda/server.conf

# This is an example server.conf file ... and documentation for all
# configurable options.
#
# Default values are left commented.

#
# Number of server processes running on this machine.
#
#numservers=1
numservers="1"

#
# Prefix of server tree
#
#vicedir=/vice
vicedir="/vice"

#
# Should the server use private mmaps for RVM
#
#mapprivate=0

#
# RVM parameters
#
# For a single server on a machine use:
#
#rvm_log=
#rvm_data=
#rvm_data_length=
#hostname=
hostname=gfqh188
#
# When a server is confused about it's identity the server will complain.
# (i.e. gethostbyname(hostname()) == 127.x.x.x). Use this option to force
# the ip-address through which clients will be able to reach this machine.
#
# The actual cause seems to be a very common setup when the machine has no
# default interfaces configured and /etc/hosts contains a line similar to
# 127.0.0.1 (or .2)     myhostname.mydomain
#
# Removing that line from /etc/hosts also solves the problem.
#
#
ipaddress=10.100.18.178
# 127.0.0.1 (or .2)     myhostname.mydomain
#
# Removing that line from /etc/hosts also solves the problem.
#
#
ipaddress=10.100.18.178

#
# For multiple servers:  Define the above 4 in a file: server_X.conf
# for a server which is started with the parameter "-n X" or define the
# following replacing X with the server number.
#
#rvm_log_X=
#rvm_data_X=
#rvm_data_length_X=
#
hostname_X=gfqh188

# The advantage of using server_X.conf files is that other parameters
# besides the rvm parameters can be defined for each server.  All
# servers should have the same vicedir. server.conf will be read first
# and then the server_X.conf file will be read.  Any definition in
# server_X.conf will override a definition of the same variable in the
# server.conf file.  e.g.  mapprivate=1 in server.conf, mapprivate=0
# in server_2.conf will have the server started with "-n 2" use
# anonymous mapping while the "default" action is to run with private
# mappings.

# Other parameters as set by startserver script.  Defaults are commented
# out if default is different than startserver script.

#
# How full the log can get before it is truncated.
#
#rvmtruncate=0
rvmtruncate=5

#
# Specify the number of rpc2 buffers to keep in a circular log, this can be
# useful for debugging.

#
#vicetab=db/vicetab

#
# Whether the server should calculate SHA checksums, this adds CPU usage
# to GetAttrPlusSHA operations allows clients to use a local lookaside
# cache to avoid fetches.
