I installed Ubuntu 20.0.4 LTS onto a fresh Samsung 250GB NVMe and used all the defaults during installation. Everything seemed to go fine but I'm not seeing that it is only showing ~100GB on the drive. How do I extend the partition

I use vscode to connect to a supercomputer using SSH remote.
I ran a selenium request from a jupyter notebook that took too long, then failed and then the bash: cannot create temp file for here-document: Disk quota exceeded started to appear when trying to complete with tab the name of a file/folder in the terminal.
These are the outputs of df and quota commands:

Obviously, I am surpassing the quota. As I told you at the beginning, this is a supercomputer, so I have limited to no access to the base folders (tmp, etc.). So, any ideas on how to solve this without cleaning tmp are more than welcome.
Hit the same issue. I cannot find any files that I own in /tmp, so I don't know why the system says my tmp quota is exceeded.
I found a work-around: change the location of my bash temp files.
$ mkdir -p ~/tmp
$ export TMPDIR=~/tmp
$ echo "export TMPDIR=~/tmp" >> ~/.bashrc
I am attempting to update my git repo by doing "git add ." within Visual Studio Code on my MAC. I have done this many times without issues but this time it is giving me this error "error: file write error: No space left on device" and "error: unable to create temporary file: No space left on device." Also when trying to clone another repo onto my device from github it says "fatal: could not create work tree dir 'cs1550-project1-domm2': No space left on device" I have 12.96gb left of 256gb. I do not know how I am out of space or how to free it. I just need to update my github repo for class.
This is running df -h within the VS terminal:

It depends on where you are trying to do the git add .
As mentioned here:
The /snap mounts come from using software packages installed with Snap.
These utilize loop devices and are usually not writable.
You will get some sort of "No space on device" error when trying to write to any of these locations and that is represented in df -h as showing those mounts as 100% in use.
But in your case, assuming the repository is in /dev/...:
devfs 392 392 0 100% 679 0 100% /dev
That means you don't have enough inodes.
Look for files to delete:
for x in /* ; do echo $x ; find $x | wc -l ; done
The goal is to free inode usage or increase the number of inodes.
I have this playbook that gather information about a server using command like df, free, sar. sorry I am very new too ansible.
Here is the playbook I am using.
- name:
hosts: all
tasks:
- name:
shell: df -h
register: mount
- name:
shell: free -h
register: ram
- name:
shell: echo "{{ mount.stdout }}" "{{ ram.stdout }}" >> prechecks.csv
delegate_to: localhost
The outcome I get is this:

As you can see the memory information is under the mount filesystem. Is there a way I can get them like this?
The way I want them to be:

I am setting up docker on a google cloud compute machine, 1 vCPU and 3.75 GB ram.
If I simply run docker-compose up --build, it does work but the process is sequential and slow. So I am using this bash script so that I can build images in the background, and skip the usual sequential process.
command=$1
shift
jobsList=""
taskList[0]=""
i=0
#Replaces all the fluff with nothing, and we get our job Id
function getJobId(){
echo "$(echo $STRING | sed s/^[^0-9]*// | sed s/[^0-9].*$//)"
}
for task in "$#"
do
echo "Command is $command $task"
docker-compose $command $task &> ${task}.text &
lastJob=`getJobId $(jobs %%)`
jobsList="$jobsList $lastJob"
echo "jobsList is $jobsList"
taskList[$i]="$command $task"
i=$(($i + 1))
done
i=0
for job in $jobsList
do
wait %$job
echo "${taskList[$i]} completed with status $?"
i=$(($i + 1))
done
and I use it in the following manner:
availableServices=$(docker-compose config --services)
while IFS='' read -r line || [[ -n "$line" ]]
do
services+=$(echo "$line ")
done <<<"$availableServices"
./runInParallel.sh build $services
I string together available services in docker-compose.yml, and pass it to my script.
But the issue is eventually all the processes fail with the following error:
npm WARN tar ENOSPC: no space left on device, write
Unhandled rejection Error: ENOSPC: no space left on device, write
I checked inodes, and on /dev/sda1 only 44% were used.

From your df -h output, root directory (/dev/sda1) has only 455MB free space.
Whenever you run docker build, the docker-client (CLI) will send all the contents of the Dockerfile directory to docker-daemon which builds the image.
So, for example, if you have three services each with 300MB directories, you can build them sequentially with 455MB available free space, but to build them all at the same time you need 300MB*3 amount of free space for docker-daemon to cache and build the images.
I logged into our production instance on AWS, and tried to go into Rails console:
bundle exec rails c production
But I'm getting the following error
There was an error while trying to load the gem 'mini_magick' (Bundler::GemRequireError)
Gem Load Error is: Cannot allocate memory - animate
When I run free I see there's no swap:

Not sure what's causing this or how to resolve it. Any help is appreciated.
Thanks!
You can increase EC2 instance memory or add swap memory to EC2.
grep Mem /proc/meminfo
grep Swap /proc/meminfo
free
uname -a
# Set swap file to /swapfile1
sudo dd if=/dev/zero of=/swapfile1 bs=1M count=512
grep Swap /proc/meminfo
ll /swapfile1
sudo chmod 600 /swapfile1
mkswap /swapfile1
ll /swapfile1
sudo mkswap /swapfile1
swapon -s
free
sudo swapon /swapfile1
free
grep Swap /proc/meminfo
