Section 53: How to setup small Fossil+Venti based Plan 9 network

Section 53: Fossil+Ventiベースのネットワーク構築

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 or Plan 9 network machine already where disk images of fossil and venti have been installed according to well described Plan 9 Wiki pages.

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).

Now, Japanese, be patient! ☺

例えば一台のノートブックにスタンドアローンのPlan 9を導入するのは、もしそのノートのハードウェアがサポートされたものだったら非常に容易なものです。 Bell-LabsのPlan 9のダウンロードのページからCDROMイメージを持って来て、それをそのままノートに差してbootし、対話的にいくつかの質問に答えるとすれば、直ちに可能でしょう。

しかし、ここから先が大変で、非常に多くの人がそこで挫折したものと推定されます。
これはもっともな事で、この種の仕事はケースバイケース、こうすればという一般的な方法を提示する事は余り有用でないかも知れないからと、いやしくもPlan 9を触ろうとする様な人ならば、自分で解決出来るだろうと期待されているからです。
ですが、この期待は多くの場合完全に裏切られている様です。そこで私は恥をしのんでここに自宅の例を載せて見る事にしました。

Fossil+Venti file serverはユーザプロセスとして動くので、standaloneの 9 terminalを kfsを使ってたちあげて、そこから起動できます。事実、普通は、この方法でFossilとVentiのディスクシステムを作りますが、私の場合は現在動いているnetwork上でFossilとVentiのディスクイメージを作りました。
いずれにしても、まずこの作業が必要です。
これについては、Plan 9のWiki pagesに優れた解説がありますので、そちらを参考にして下さい。ここでは、この作業は既に終了しているものと仮定します。

ちなみに、ここで設定する独立のFossil+Ventiマシンは、CPU server(正確にはAUTH server)がないと認証が行えませんので、それはPlan 9システムと呼ぶのは問題があります。どこかにこのAUTH SERVERを持つ必要がありますが、それをFossil+Venti server上に持つ事も可能になっています。これはFactotumが開発されたからに他ならず、この事情は上のkfsベースのスタンドアロンサーバの所で述べた事です。

別の言い方をすると、このAUTH server+Fosiil+Ventiが出来ますと、それ一台だけでも、取り敢えずPlan 9のネットワークの構築は可能で、また、そのサーバマシン上でrio環境は可能で、ここが以前のKen Thompsonのファイルサーバとの違いです。

更に、Fossilはlong nameを扱えますので、lnfs(4)が必要なくなります。でも、このマシンは CPU serverとして動きますので、一人しかloginできません。☺

では、成功を祈ります。

1) fdisk and prep sdC0 and sdC1

Mine is as follows:

All the partition of sdC1(80GB) is dedicated to Venti.

You have to add an item of pcvnsf to mkfile, of course. My pcvnsf file is as follows:

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:

6) reboot the machine without floppy

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!
