I got a Linux machine of 1TB. The storage structure is like this:

/dev/xvda1            9.8G  1.9G  7.8G  20% /. 

tmpfs                  30G     0   30G   0% /dev/shm. 

/dev/nvme0n1          1.8T   20G  1.6T   2% /local.

Now I have my processes run on /tmp folder and my application is failing because there is not enough memory present on device.

How do I get the storage in /local directory to / directory.

You could create a directory under / like so:

sudo mkdir /new_local

Then bind the /local directory to it like so:

sudo mount --bind /local /new_local

This way all the space and contents of /local will be accessible under /new_local

If however your goal is to extend the storage space on /tmp using the available space on /local then please follow the two steps below:

First, create a directory under /local like so:

sudo mkdir /local/new_tmp

Then, bind it to /tmp like so:

sudo mount --bind /local/new_tmp /tmp

This way all the available free space under /local will be given to /tmp
