A loop device is a pseudo-device that can turn a computer file into a block device.
To be able to see all the "used" loop devices on a system, we use the below command:
To delete all the loop devices on a system, we use:
To delete a loop device using its name, we run the below command:
Using a loop device as storage:
We start our process by making a directory that is going to serve as a mountpoint for our device:
We then create a raw disk file of "1G" using the "dd" utility:
To see the first available loop device, we use the below command:
We use the below command to associate our loop device "/dev/loop1" with the raw disk file we have just created with the "dd" utility:
We could then partition it using the parted program.
We label our device with the "mbr" label using the below command:
Then we create two partitions partitions "/dev/loop1p1" and "/dev/loop1p2":
To check is our "loop1" is showing on the system, we use the below command:
We might need to run so that the changes are reflected in the system:
The we create a filesystem on one of the partitions using the below command:
Then we mount it, on the "data" directory to be able to use it:
We can unmount our device once we have no use for it, using the command:
