# # This statement specifies the defaults; any # variables set here apply to all entries # unless overridden. I simply set two NFS # options: # nosuid = don't allow suid programs # nodev = don't allow device files # doc type:=nfs;rhost:=doc-server; \ rfs:=/usr/local/docs
# This statement is one of the simplest volume # specifications. It assigns a location # /u/doc, which maps to the directory # /usr/local/docs on the machine # doc-server. home/crosby host==cia;type:=link;fs:=/a/home/crosby \ host!=cia;type:=nfs;rhost:=cia;rfs:=/a/home/crosby
# This entry is slightly more complicated. # It specifies information about my home # directory, on the machine cia. Basically, # it accomplishes the same thing as the # preceding entry, except that when the machine # in question is the host itself it simply acts # as a symlink to the location rather then # mounting it; thus, the performance problems # of a machine mounting off of itself are # avoided while at the same time single map # for all hosts is allowed. # Note that the directory is UFS mounted in the<\n> # same place that AMD would NFS mount it, # under /a. tools arch==pa-risc;wire==net1;type:=nfs; \ rhost:=nag;rfs:=/tools \ arch==pa-risc;wire==net2;type:=nfs; \ rhost:=nagina;rfs:=/tools \ arch==dec-mips;wire==net1;type:=nfs; \ rhost:=frisbee;rfs:=/tools \ arch==dec-mips;wire==net2;type:=nfs; \ rhost:=aerobie;rfs:=/tools \ arch==i386;wire==net1;type:=nfs; \ rhost:=hazelrah;rfs:=/tools \ arch==i386;wire==net2;type:=nfs; \ rhost:=pipkin;rfs:=/tools \
# This entry is quite complicated. It has a mount # point that varies depending on which network the # machine resides (the "wire" variable, which can # take symbolic network names or ip addresses) and # which architecture (HP, # PC/linux, PC/solaris, or # DEC) applies to the machine. By setting the # mount point this way, the users know they can # go to /u/tools and get the correct binaries for # the current architecture mounted off the local # network--regardless of which machine # they are using home/* -opts:=nosuid \ hosttype:=nfs;rhost:=${key};rfs:=/home/${key}
# This statement is a wildcard map--any entry # /home/whatever is mapped to machine whatever. # Having a wild card map is very useful: I can now # have hundreds of machines with home directories, # and still have only one map entry. And to add a # new one, I simply have to add the machine and # export it--I don't have to modify the map. # # This statement also shows how to designate entry # specific NFS options; I don't want to allow # suid programs in home directories, so I turn it # off (-opts:=nosuid). <\n> data type:=nfs;rfs:=/data rhost:=server1 \ rhost:=server2 rhost:=server3
# This statement sets up a replicated server. # If we have important data, we want to make # sure it will be available even if a server # crashes. This data ia replicated over three # servers, and AMD will mount from whichever one # it can.
