Hi,
I just downloaded the kbuntu iso and installed it on a 8GB pendrive. Everything looks fine, really nice. When I wanted to update/upgrade: apt-get update, apt-get upgrade It failed because of insufficient memory. Looking at the disk partitioning i realized that the virtual / partition is only 1Gb big. the whole stick is mounted as /cdrom correctly with >6Gb free. I looked a bit around but i could not find a description how to increase the virtual partitions on the live stick. Do you have any hints? Thanks a lot, hansjoerg Last edited by hansjoerg; August 13, 2010 at 16:33. |

Greetings hansjoerg,

I haven't tested this installation in a USB drive yet, but my guess is that there wasn't any space allocated for working with files! And if /cdrom has the whole 6GB space for itself, it might be defined as read-only. By my experience with Live Ubuntu's in USB drives, lets try the following commands, and perhaps you can post your results here:
OK ok... lets go back a few steps... Hansjoerg: how exactly did you install the ISO in the USB drive? Did you install it as a Live CD/DVD/USB or as if you were installing in a hard drive? For more instructions for Ubuntu's Live USB, see here: https://wiki.ubuntu.com/LiveUsbPendrivePersistent Best regards, Bruno

Hi,
Thanks for the detailed instructions. I will try that out. I installed the iso as a live-cd using the usb-creator which comes with ubuntu and I also tried out UNetbootin The partitioning of the stick is as follows ilesystem Size Used Avail Use% Mounted on aufs 1003M 39M 964M 4% / none 998M 292K 998M 1% /dev /dev/sdc1 7.5G 1.6G 6.0G 21% /cdrom /dev/loop0 1.3G 1.3G 0 100% /rofs none 1003M 0 1003M 0% /dev/shm tmpfs 1003M 92K 1003M 1% /tmp none 1003M 92K 1003M 1% /var/run none 1003M 0 1003M 0% /var/lock none 1003M 0 1003M 0% /lib/init/rw and actually the cdrom was really mounted readonly, but i cannot unmount and remount it due to the fact that the root file system is on the stick. I have a casper directory with 1.3 GB big filesystem.squashfs After the update /tmp is 100% full and dpkg breaks with the error message that it cannot write on device anymore. Then kde hangs up. Should i make a normal install on the stick to get a "normal" ubuntu installation. This definitely then would require much more space on the stick, but if it is too complicated to create a "rw" live image, then i can also go this way thanks hj best hansjoerg Last edited by hansjoerg; August 17, 2010 at 09:07.

Hi hansjoerg,
Quote:
Attached is a picture with notes in red, indicating where you should define casper-rw file to be active. Pull the slider to the extreme right... it should give you 2 or 4GB of workspace. The slider will only be available after picking the USB drive and ISO... both of which I didn't do for the picture Then write again to the USB drive and you should be ready to go! But since you want to do a lot of upgrades to the Live DVD, then you better follow these instructions for installing Ubuntu (while taking into account that you are using KUbuntu) directly on an USB drive: How To: Install Portable Linux Ubuntu on a bootable USB Flash Drive from SUN VirtualBox Best regards, Bruno

Hello Henrick,
I am trying to install the tgz version of OpenFOAM Workshop-USB-Stick but I am having a problem. I downloaded the .tgz file on to my laptop, and then extracted the compressed file in the USB stick. Then, I ran the boot/bootinst.sh and it said that the drive is bootable now. However, when i change my boot preference and boot my device from the USB stick, it gives me the following message : No default or UI configuration directive found. boot :/ I have no clue as to how to solve this problem. Can you help me out with the installation

Henrik,
The USB iso is a fantastic idea. I have successfully loaded my 8Gb drive with the iso image. But I am not getting happy yet. First I tried it on my IBM T-60. Not a 64 bit machine - failed. (IS THERE A 32 BIT VERSION?) Then I put it in my W520 from work. I get a Welcome screen with 5 options. The first is "live - boot the Live System" This sounds good, so I go for it. But it thinks and thinks and eventually says it can't find any media with a live System. ??? There is also a "start the installer directly", but won't this try to write to my (sacred company's) hard drive? Thanks. Albert |

Those live images were containing some files we could not longer distribute. So we had to remove them. Martin |

In previous years, live-usb images were created as support material for the Workshop's training, and quite often distributed pre-installed on USB sticks to the Workshop participants. So I would not be surprise if a new live-usb version will pop up just before OFW9... Martin |

I was wondering whether a live sub has been created for OpenFOAM v7 now as a live usb created last time was for the version 5 and as it was so helpful for everyone without a linux operating system installed, it would be great if anyone shared their knowledge regarding this topic.
