[9fans] building small Plan 9 network at home (LONG)

[9fans] building small Plan 9 network at home (LONG)

[okamoto]

It's very straightforward to have a standalone Fossil+Venti
machine at home.   However, i'm afraid it's not so easy to
have that network at home.   So, this is my small attempt to
offer an example of mine with the hope to help someone
who wants to has Plan 9 home network.

Here, I assume you have standalone kfs based machine already.

My Plan 9 network at home is very small, which has only three
machine, called venus(Venti+Fossil+CPU server), surveyor(RedHat
9.0 or Plan 9 terminal) and mars(Win2000 or Plan 9 terminal),
and the purpose of this document is to build venus.   Mars and
Surveyor will boot from floppy drive when I want to run 9term.
Venus server has two disks, sdC0 and sdC1, and will boot from
sdC0 using 9fat partition.

Regarding how to make venti/fossil file system, you can read the
related documents on Plan 9 wiki page.  I think it's worth to add
a point here.   Don't forgewt to fossil/flfmt /dev/sdC0/other before
to make it run.   You'll have active, snapshot and archive directory
under the other filesystem, those are not neccessary, and you can
remove them from fossilcons(8), and add some neccessary diectories
there, such as lp/tmp, lp/log etc.

Now, let's go  (may be long sorry).



1) fdisk and prep sdC0 and sdC1
  Mine is as follows:
	sdC0
    --rw-r----- S 0 sys sys   104857600 Dec 23 15:39 /dev/sdC0/9fat
    --rw-r----- S 0 sys sys           0 Dec 23 15:39 /dev/sdC0/ctl
    --rw-r----- S 0 sys sys 20490559488 Dec 23 15:39 /dev/sdC0/data
    --rw-r----- S 0 sys sys  8821071872 Dec 23 15:39 /dev/sdC0/fossil
    --rw-r----- S 0 sys sys  4831787008 Dec 23 15:39 /dev/sdC0/isect
    --rw-r----- S 0 sys sys         512 Dec 23 15:39 /dev/sdC0/nvram
    --rw-r----- S 0 sys sys  6194552832 Dec 23 15:39 /dev/sdC0/other
    --rw-r----- S 0 sys sys 20489140224 Dec 23 15:39 /dev/sdC0/plan9
    -lrw------- S 0 sys sys           0 Dec 23 15:39 /dev/sdC0/raw
    --rw-r----- S 0 sys sys   536870400 Dec 23 15:39 /dev/sdC0/swap

  All the partition of sdC1(120GB) is dedicated to Venti.

2) The contents of 9fat partition

    --rw-rw-rw- M 55 bill trog     411 Dec 23 05:51 /n/9fat/PLAN9.INI

	Plan9.ini of venus is as foolows:

	#bootfile=sdC0!fs!/386/9pcauth
	bootfile=sdC0!9fat!9pcvnsf

  Don't bother with audio0 line. ☺

   And, mk 'CONF=pcvnsf' install, and copy 9pcvnsf(.gz) to 9fat
   partition, too.

  You have to edit following three files under /sys/lib/sysconfig/venusf
   directory before compile 9pcvnsf.   My /sys/lib/sysconfig/venusf/boot, 
   vnsfproto, venti.conf files are:

The ether=xxxxxxxxxxxx should be replaced by an approapriate
number.

5) reboot the machine without floppy, and it'll boot from the sdC0,
and reads plan9.ini thre, and you'll be promted to enter authID,
authdomain and key etc, and do it which will be written to /dev/sdC0/nvram,
and from next time, it'll be read automatically.

good luck!

Venus has 256x2 + 32 = 544MB memory, and Mars has 256MB
and Surveyor's 512MB memory.
