Or $35 RPi4 in 2020 which might even raise your hard-disk transfer rate
well above the current USB2 theoretical max of 60 MBytes/sec -- just don't
count on SATA or NMVe or M.2 (:

My point earlier was simply that well-meaning people who are unfamiliar
with the developing world (quite the opposite of Tony Anderson) should
avoid wasting their money buying $68 400GB
 and $130 512GB
 microSD cards for Raspberry Pi...the
reasons are not always obvious in the rich world:

   1. Tiny $~100 items (a microSD card is smaller than a penny) can
   "silently disappear" in classrooms/countries where that represents a
   month's salary.  Recriminations across the school become very serious in
   cases of theft, sometimes resulting in cancellation of their computer
   program.  Yep "thoughtless generosity" can frequently backfire.
   2. Even the temptation of theft can create dangerous social disruption
   in impoverished schools/countries especially -- whereas a wealthy volunteer
   typically won't give a thought to $100, not realizing this is equivalent to
   leaving $10,000 in cash completely unprotected in a classroom in a rich
   part of the world -- e.g. in places like NY City where teachers salaries of
   $100,000 to $120,000/year exist (and are no longer uncommon).
   3. A USB hard disk can be a much better use of funds than a microSD card
   among groups that want a "full library experience" (as you point out).
   Particularly if they have people who are experienced/intelligent enough
   (like yourself) to fill those TB disks with high-quality and
   locally-relevant local-language materials.  Conversely I've met many
   well-meaning NGO's and govts who do not have a clue how to fill even a
   fraction of their 1TB disks with pedagogically relevant/useful/legal OER's
   (open educational resources) *so our road remains long :)*

Hi, Adam

As you know this is an area where we agree to disagree. Currently the 
schoolserver's valid, useful content exceeds 500GB. I really do not want 
to get into the game of deciding what is worthwhile and what is not. It 
is clear that the planned expansion of OSM will require increased 
capacity. If local content is seriously supported, the amount will 
increase even further. At one time OLPC estimated storage of the Journal 
would take 2GB per XO. A typical Rwanda school has 200 XOs potentially 
requiring 400GB of additional space.


My dream is an RPi3 based schoolserver with a 1TB (or 2TB) external 
hard-drive at under $150 (about 1/3 of NUC-based server).

Re: [Server-devel] Booting from a big USB stick

2019-03-19 Thread Tony Anderson


Hi, Gerhard

The trick is to separate the server software from the content. Install 
the basic IIAB on a smaller SD card (e.g. 16GB). Then mount the 128GB 
usb drive (mount /dev/sdb1 /media/usb0 for example). IIAB expects the 
content to be in /library. This should be possible by a symbolic link 
such as /media/usb0/XC /library. XC is a folder containing the content 
whereas usb0 is a partition. The original installed content in /library 
on the sd card needs to be copied to the XC folder on the USB stick 
before the symbolic link is made. In principle, Ansible should recognize 
the /library (XC folder) and operate as expected.


Tim Moody has an img of the basic installation which should be perfect 
to set up the SD card (simple dd). I am looking forward to trying that. 
I am hoping that the img sets the 'box' (hotspot). This should mean 
everything can be done headless via ssh.


As always, it will be an adventure.

Tony

Hello all,

i am gerhard from berlin and i am experimenting with iiab

i succeded in booting my raspberry pi model b3+ from a 128 GB USB Stick
(costs are only 18€)
ok
then i wanted to let work this magic sentence

curl d.iiab.io/install.txt | sudo bash

but i got an error message in the beginning:

tune2fs: Datei oder Verzeichnis nicht gefunden beim Versuch, /dev/mmcblk0p2
zu öffnen
Es kann kein gültiger Dateisystem-Superblock gefunden werden.
root@raspberrypi:/home/pi#

so i stick in this.

any solution for this problem

That seems to be German for:

Can not find a valid file system superblock.


What exact OS are you running?

Internet-in-a-Box strongly recommends Raspbian -- any one of the 3 from
this page:
https://www.raspberrypi.org/downloads/raspbian/


PS click "installation guide" near the very top of that page if you're not
used to burning/flashing images using Etcher, Win32 Disk Images or "dd".

HI Gerhard,

Can you please use a microSD card, instead of a USB stick?

Internet-in-a-Box is not normally installed onto a USB stick!

In fact I don't know if this has ever been attempted before, so you're
making your life difficult :-)

Then again if that is your choice, it is possible
