These steps are dedicated for creating a pen drive with a partition size that should fit all 8GB USB drives, including those that _lie_ about their total size, such as those that really only have around 7,750,000,000 bytes. The following instructions aim for a primary partition of 7,654,604,800 bytes.
+
This is aimed at providing a fully functional USB-stick or Virtual Machine Appliance that works on VirtualBox, so that [http://openfoam.org OpenFOAM] and [http://foam-extend.org foam-extend] can be accessed without going through the occasionally tough installation process. Nonetheless , keep in mind that [http://www.docker.com Docker] is the kind of technology that will probably supersede this kind of installation in future workshops.

Need to have {{tt|usb-creator-gtk}} installed and we will be using Lubuntu 64-bit as the basis for our pen drives. In addition, it's advisable to do these steps from a working installation of the desired Lubuntu version, even if it's within a virtual machine.
+
−
 
+
−
# As root (or with {{tt|sudo}}), run:
+
−
<bash>usb-creator-gtk</bash>
+
−
# Select the ISO for the Lubuntu Live CD/DVD.
+
−
# Select the pen drive you want as the target for the Live USB.
+
−
#* '''Note''': Do not use the erase function, otherwise you will loose the correct booting mechanism that was created with {{tt|fdisk}} and {{tt|mkfs}}.
+
−
# Select the largest possible "Stored in reserved extra space", at least taking into account how much will be left over for the _read-anywhere_ files, such as presentations and VM installers.
+
−
#* For example:
+
−
#** 690 MiB for the cloned Live CD
+
−
#** 1.0 GiB for the _read-anywhere_ data.
+
−
#** 7.1 GiB - 1.0 GiB - 690 MiB = 5.42 GiB = 5556.4 MiB... which is larger than 4GiB, the file size limit for FAT32 partitions.

# Finally, click on the "Make Startup Disk" button and wait a while for it to run...

=== Transferring the local installation to the persistent partition file in the drive ===
+
−
 
+
−
'''Note''': These instructions will mount and transfer the files directly to the persistent file in the USB drive, so you might want to not operate directly on this file.
+
−
* If so, copy the file {{tt|casper-rw}} to a local disk and roughly follow the steps accordingly with the new path for the file.
+
−
 
+
−
Steps:
+
−
# Mount the pen with the interactive mount that Lubuntu has got from the file manager.
+
−
# As root (or with {{tt|sudo}}), run:
+
−
<bash>mkdir /mnt/casper
+
−
mount -t auto /media/$USER/*/casper-rw /mnt/casper/ -o loop
+
−
</bash>
+
−
# The _persistent_ home folder will now be located at {{tt|/mnt/casper/upper/home/lubuntu/}}:
+
−
<bash>cd /mnt/casper/upper/home/lubuntu/</bash>
+
−
If it doesn't exist, then create it and change owership:
+
−
<bash>mkdir -p /mnt/casper/upper/home/lubuntu/
+
−
chown -R 999:999 /mnt/casper/upper/home/lubuntu/</bash>
+
−
# When you're done copying files to the image, make sure the _persistent_ home folder has the correct owner permissions:
+
−
<bash>chown -R 999:999 /mnt/casper/upper/home/lubuntu/</bash>
+
−
# Then unmount it:
+
−
<bash>umount /mnt/casper</bash>
+
−
# Also unmount the pen:
+
−
<bash>umount /dev/sdX1</bash>
+
−
 
+
−
 
+
−
== Cloning the original pen to a new image ==
+
−
 
+
−
Steps:
+
−
# Make sure you don't have the pen mounted! Example to umount:
+
−
<bash>umount /dev/sdX1</bash>
+
−
# As root (or with {{tt|sudo}}), run:
+
−
<bash>dd if=/dev/sdX of=OFW11-2015_v1.img bs=512 count=14950463</bash>
+
−
#* The value "14950463" is the End sector count 14950462 plus 1.
+
−
#* 14950463 sector * 512 B/sector = 7654636544 B = 7654636544 ~= 7300 MiB
+
−
## In another terminal (also as root), tun:
+
−
<bash>while killall -USR1 dd; do sleep 30; done</bash>
+
−
## Then look at the previous terminal window and every 30 seconds it should update on the current write status. Given how this command works, if you have more than one {{tt|dd}} running, it will update for all running {{tt|dd}} applications.
+
−
# When it's done cloning, make sure the file system is synced:
+
−
<bash>sync</bash>
+
−
wait until it returns control back to you.
+
−
# Now you can mount the pen again, if you want. Or simply eject it.
+
−
 
+
−
 
+
−
== Cloning the image to a new pen ==
+
−
 
+
−
It's almost the reverse of the previous steps:
+
−
# Make sure you don't have the pen mounted! Example to umount:
+
−
<bash>umount /dev/sdX1</bash>
+
−
# As root (or with {{tt|sudo}}), run:

−
<bash>dd if=OFW11-2015_v1.img of=/dev/sdX bs=512</bash>
+
−
## In another terminal (also as root):
+
−
<bash>ps -a</bash>
+
−
## In another terminal (also as root), tun:
+
−
<bash>while killall -USR1 dd; do sleep 30; done</bash>

1 Preface

This section of the wiki (Installation/Live_Images/USB-Stick for OFW11) has been written as the most detailed as possible set of instructions on how to create, successfully massively-deploy USB-sticks and alter use those USB-sticks that run Lubuntu with the all of the OpenFOAM technology software that was available up to a few months from when the 11th OpenFOAM Workshop is/was held in 2016 at Guimarães in Portugal. Website at the time: openfoamworkshop.org

2 Objective

To make it 100% probable that everyone will be able to use OpenFOAM and foam-extend at the 11th OpenFOAM Workshop. Although this might be limited to 100% of the people that have 64-bit PCs...


3 Instructions

This is aimed at providing a fully functional USB-stick or Virtual Machine Appliance that works on VirtualBox, so that OpenFOAM and foam-extend can be accessed without going through the occasionally tough installation process. Nonetheless , keep in mind that Docker is the kind of technology that will probably supersede this kind of installation in future workshops.

The information written for this topic are spread across the following sub-pages:

User Guide
This is the User Guide meant for the people who will be trying to use these images and/or virtual machines. It also lists the software versions installed with the image designed for this workshop.
Reminders
This page is needed for the next couple of pages, because this provides the main details that should be kept at all times when following the instructions on those other pages!
Deployment Guide
This page is meant for the people responsible for the deployment phase, namely those who will be sweating to burn the image onto several dozens (if not a couple of hundred) USB sticks.
It also includes information on how to create the virtual machine appliances, in case things don't run so well when trying to use the USB-stick as a bootable drive.
Creation Guide
This is where the complete instructions for the creation of the USB-stick are written and provide as many details as possible.
Download
This is where is listed the current locations for the (virtual) disk images.
Frequently Asked Questions
This page is for the Frequently Asked Questions about this particular effort for the OFW11.
