Symbolic Link

What is a symbolic link?

A file-system shortcut that points to another file or directory by storing its path, allowing transparent access from an alternative location.

A symbolic link (also called a symlink or soft link) is a lightweight file-system object that acts as a pointer to a target file or directory. Rather than duplicating data, it stores the path to the original. The operating system follows that path transparently when the link is accessed. This makes symlinks useful for organizing complex directory structures, creating shortcuts, and referencing files across different storage volumes or file systems.

Unlike hard links, which tie directly to the underlying data, symbolic links depend on the target’s path. If the target is moved or deleted, the symlink becomes “dangling,” pointing to a location that no longer exists. This flexibility-versus-fragility tradeoff makes symlink management important in large-scale environments.

In metadata-driven platforms like Starfish Storage, symbolic links are cataloged as distinct metadata entries across heterogeneous file systems such as Lustre and GPFS. This visibility lets administrators detect broken links, streamline data cleanup workflows, and maintain accurate file relationships without disrupting production systems.
