Storage of files for a distributed setup?

I’m working on setting up cluster on local hardware that I can access from outside my home network. I want to store all the files on an extra hard drive that is mounted to the machine running WebODM. In the below diagramed setup with 3 machines, are there files from uploads/processing that would persist somewhere other than the local storage location set via the --media-dir parameter? Do I need to worry about storage on the NodeODM machines beyond what is required for processing the split groups for a single processing task?

Both the documentation and the below post were helpful.

As far as NodeODM go, do you need to worry about storage? Maybe. NodeODM does keep tasks in storage for 2 days by default (to allow for restarts). So if you process a lots of tasks within a 2 day frame, you might have a lot of files.

You can remove them immediately by running NodeODM with the cleanup_tasks_after flag: NodeODM/config.js at master · OpenDroneMap/NodeODM · GitHub

If disk space is a concern, and you don’t need the ability to restart tasks from the middle of the pipeline also check the --optimize-disk-space option when processing tasks. It will decrease overall disk utilization by a lot while processing.


Since Dan is among the very few who handles massive datasets, this is a consideration for sure. I have run out of space due to caching in ClusterODM, but due to how I have storage allocated, it’s much more common for me on individual nodes.
