I am facing issue in a docker container startup. At starup of the docker container, I want to create softlinks of about 300-400 links in root-volume which is C_drive inside a docker container. The Source of the folder is EBS-volume which is mounted as D_drive. The destination is in the root-volume(C_drive). The EBS-volume(D_drive)is full, the root-volume has enough space. At the time of starting the container which is ubuntu version 20.02 the softlinks are created. I am getting error "Out of space" while creating the softlinks. The destination folder for softlinks is root-volume, why I am getting error "Out of space". As a solution, I freed 1 MB file in the EBS-Volume, then the softlinks are getting created. Once the soft links are created I am able to copy back the 1 MB file. If the softlinks creation occupies space, why I am able to copy back the 1 MB file? Why does the softlinks creation needs space in the EBS-volume(D_drive)?

The host machine has Amazon Linux2

The command used for Soft Link creation is,
eval ln -nfs "$SOURCE/*" "$DESTINATION/" || error_notification

erro_notification is a shell function for handling and logging the error.

What is the purpose of eval here? I'd rather
Pay attention to the quoting of $SOURCE (I highlighted the difference).

Its not the syntax issue, it is working fine when enough disk space is available. My query was on the disk space that is required to create sim links.
