Would creating standard operating procedures f= or newcomers be beneficial? Having procedures detailing how to administer V= enti mirroring on a Plan 9 system in a wiki seems reasonable. Here is a for= matted example of an SOP. I am sure something better could be created.

 
Standard Operating= Procedure for Setting Up and Managing Venti with Automatic Mirroring in Pl= an 9

Purpose
This do= cument provides a step-by-step procedure for setting up and managing Venti,= an archival storage system in Plan 9, with automatic mirroring.

Scope
This SOP covers the initial co= nfiguration, formatting of indexes and arenas, starting the Venti server, s= etting up automatic mirroring using `fs(3)` and `venti/mirrorarenas`, and p= erforming backup and restoration.

Responsi= bilities
- System Administrator: Responsible for setting up= , configuring, and maintaining the Venti system.
- Backup A= dministrator: Ensures regular backups and mirroring of Venti data.

Procedure

1. Init= ial Configuration of Venti

1.1 Prepare Con= figuration
- Use the `venti/conf` tool to define the config= uration.

    venti/conf
    arena /dev/sdE0/arena
 = ;   arena /dev/sdN0/arena
    inde= x /dev/sdE0/index
    addr tcp!*!17034
=
   

2. Formattin= g Indexes and Arenas

2.1 Format Index and = Arenas
- Format the index and arenas to establish the neces= sary data structures.

    v= enti/fmtisect -b 8k index /dev/sdE0/index
   = ; venti/fmtarenas -a 512M arena /dev/sdN0/arena
  = ;  venti/fmtarenas -a 512M arena /dev/sdE0/arena

2.2 Initialize the Index
- Initialize the index= using `venti/fmtindex`.

   = ; venti/fmtindex /path/to/venti.conf

3. St= arting the Venti Server

3.1 Start the Serv= er
- Launch the Venti server with the following command:

    venti/venti -c /path/to/v= enti.conf

4. Setting Up Automatic Mirrorin= g

4.1 Mirroring with `fs(3)`
- Use `fs(3)` to mirror a block device, configuring it to sync the parti= tions containing the arenas and index.

&nb= sp;   fs(3) -m /dev/sdE0/arena /dev/sdE1/arena
&n= bsp;   fs(3) -m /dev/sdE0/index /dev/sdE1/index
<= br />
4.2 Automate Mirroring with `cron`
- Automa= te the mirroring process using a cron job.

    cron '*/5 * * * * fs(3) -m /dev/sdE0/arena /dev/sdE= 1/arena'

4.3 Using `venti/mirrorarenas= `
- Create a script to mirror the arenas using `venti/mirro= rarenas`.

    #!/bin/rc
    venti/mirrorarenas -v /dev/sdE0/arena /dev/= sdE1/arena
    venti/mirrorarenas -v /dev/sd= E0/arena /dev/sdE2/arena

- Save the script= as `mirror` and schedule it with `cron` for regular execution.
=

    cron '*/5 * * * * /path/to/mir= ror'

5. Backup and Restoration

5.1 Backing Up Arenas
- Use `vent= i/rdarena` to extract an arena to external media.

    venti/rdarena /dev/sdC0/arena arena.0 > /path= /to/external/media

5.2 Restoring Arenas
- Use `venti/wrarena` to restore blocks from an arena file to= a Venti server.

    venti/= wrarena -h venti2 /path/to/external/media

= Notes

- Data Integrity: Venti’s writ= e-once nature ensures data integrity.
- Deduplication: Vent= i’s use of cryptographic hashes ensures efficient storage through ded= uplication.
- Scalability: Venti can scale by adding more s= torage arenas.

Documentation

- Configuration File: Keep a record of the Venti config= uration file.
- Cron Jobs: Document and review cron job sch= edules regularly.

Review and Update
<= /div>

- Annual Review: This SOP should be reviewed ann= ually to ensure it remains current and effective.
- Inciden= t Review: Any incidents should trigger an immediate review and possible upd= ate of this SOP.
