For my cluster project I will add a new user to each Raspberry Pi. This is so the user I use for all other systems will be the same on the Raspberry Pi’s. This post describes how to add another user to Raspbian OS.
Since the first Raspberry Pi was released in 2012 there have been a number of changes to their design. Since I plan to include a number of different models in my cluster I will review and test each model to find its weakness and strengths.
To set up my cluster I want to create single SD card image then run this same image on multiple Pi’s. This means I wont need to set up each Raspberry Pi at a time. One of the ways you can do this is by taking an image of the raspberry Pi then flashing that
The Raspberry Pi foundation have recently updated their Raspbian image. This brings bugfixes and upgrades to the Raspberry Pi. In this blogpost I share how you can run a command on your Raspberry Pi without logging in (this is mostly true although you still do “log in” just not in the typical way). This includes
When trying to mount an encrypted drive using Veracrypt I encountered this error: chewett@bunker-master2:/mnt$ veracrypt /dev/sdc1 gen500 Enter password for /dev/sdc1: Enter PIM for /dev/sdc1: Enter keyfile [none]: Protect hidden volume (if any)? (y=Yes/n=No) [No]: Error: device-mapper: reload ioctl on veracrypt2_0 failed: No such file or directory I did some research and found out that
Now I have the power supply and built the stacking system I can show off the clusters initial state. Every Raspberry Pi in the cluster Here are the 7 initial Pi’s that are to become part of the cluster. Each have been given a codename to designate its position in the cluster. The Raspberry Pi designed “M” will be
If you are getting “Read-only file system” on your Raspberry Pi when mounting drives there is a simple fix. chewett@bunker-master2:/mnt/wd500$ touch test.txt touch: cannot touch ‘test.txt’: Read-only file system I noticed this happening when I tried to mount and work on my external hard drive. This is formatted with the NTFS filesystem. I did some
