![]() ![]() This way i started setting up my network boot infrastructure. At the same time this will serve me as sparing to learn everything about this network booting thing. I though I would be a good idea to install some linux distro on the hard drives to partition and have a fail-safe boot in the machines. In a near future I would like the nodes to boot from a network image, so I minimize configuration to be done. I was surprised of how heavy each of this tinny guys is: the package containing both was 20 kilos! The solution for the power distribution currently looks like: ![]() If this is because the price of copper, I could resell the copper cooler pipes if this project does not work out and maybe break even. I would had never though that those are such an expensive thing. Reducing the size of all this 220 Volts power cords into some other system that feeds all the nodes would be pretty nice to have as well. Like for example hiding all the wiring that feeds the nodes. The collective arrangement presents new challenges that were never addressed in the original case. This project started with the need of building something, so reusing the cases is out of the equation: sorry to all those dell engineers that did such a great job squeezing all this components in 24x24x7 (specially to that one guy who cut a square off the motherboard to fit the system fan). They are not easy to replace because in the first place you may not need to do so. The Optiplex cases are pretty neat, they stack on each other, they have a good ventilation system and can be placed vertically or horizontally. Still an outgoing project to decide what and how to build it. Last week I have been doodling how the new case would work. Measuring and imagining the new housing Luis Ayuso.Sudo cp to_be_sysfs/boot/initrd.img-4.4.0-128-generic image/casper/initrd.lzĪnd here is where we stop. Sudo cp to_be_sysfs/boot/vmlinuz-4.4.0-128-generic image/casper/vmlinuz Sudo apt-get install syslinux squashfs-tools genisoimageĬp to_be_sysfs/boot/vmlinuz-4.4.0-128-generic image/casper/vmlinuz But this was fixed with a system reboot (although if the resource was blocked, there should be a reason for it). I can not locate which process keeps the resource busy. Everithing seems to work fine in the host, so it was a success Back to the host it asked questions that were not described in the web, I got pretty scared that I was flashing the boot partition of the host system, I closed my eyes and selected one of the options. but a fast google came out with that one that seems to work, because it downloads stuff. Here the problems begin, first whit finding out what PPA GPG key to use. Sudo apt-key adv -keyserver -recv-keys 399B698EEA9EF163B6F9A0F62CC98497A1231595 apt-get updateĭpkg-divert -local -rename -add /sbin/initctlĪpt-get install -yes ubuntu-standard casper lupin-casperĪpt-get install -yes linux-generic apt-get install -yes grub2 Sudo add-apt-repository ppa:ubuntu-desktop/ppa Inside the Fake Linux:Īnd then after chroot we are like in a fresh system (so fresh that does not have anything)Ĭat /proc/cpuinfo mount none -t sysfs /sys no issues here as the target ISO is the same distro version as the host machine. I copied some network configuration and the package manager configuration. Sudo cp /etc/apt/sources.list to_be_sysfs/etc/apt/ Sudo debootstrap -arch=amd64 xenial to_be_sysfs The following code creates some sort of fake filesystem and then we can "boot" the fresh system inside: Nevertheless one must fill the gaps when following this document: prepare the host add filesystems to my ISO, (ideally I would like to have home in the network, but a local scratchpad mount using the node hdd)Īs my ISO is based in Ubuntu16 (don't look at me like that, the man has constraints) I found a compresive list of steps to follow here:.boot from that ISO -> fight again the UEFI vs BIOS monster.Create an ISO I can boot: (ideally with pre-installed compilers and stuff).Today I gave a fresh try to the tandem networkboot-customiso.Īs the network boot is already working, I will try to explain the steps to create the iso and make it available over tftp boot. ![]()
