LucidLink is a scale-out distributed file system that sits on top of object storage. LucidLink splits the data from the metadata and chunks data to a specific block size. As there is virtually no limit to the size of a LucidLink Filespace, aside from potential constraints placed on buckets by specific object storage providers, it may be a little harder to quickly see disk usage statistics in LucidLink. 

On Windows, a LucidLink Filespace can show up as an endless mount point, that never fills up. On macOS and Linux, the mount point does not have associated used size information. 

You can see the total size of the Filespace, excluding any snapshots, by reviewing the "File system size" information in the LucidLink Client user interface.

You can also see the actual amount of data stored in the Azure blob, or S3-compatible storage by reviewing the "Used storage" metric in the same dashboard:

To see how much space is used per file or folder, you could right-click on files and folders in the LucidLink Filespace and select properties, or by using du -bsh on Linux.

Please note, that this calculates the size of the Filespace (mount-point) and does not include the disk space, used by the LucidLink Client in cache or metadata (the internal `.lucid`) folder.
