During #wikimedia-hackathon-2023 it was mentioned a couple of times how convenient it would be to have something similar to cinder volumes but for toolforge tools.
We could have a command line interface to create/manage different storage kinds. This has been [[ https://email@example.com/thread/CHGYMEUYSIFU3AIVPXFKEFIDT7UK6YV2/ | previously suggested ]], some kind of `toolforge storage [..]` interface, with options to manage different backends:
* Ceph RBD volumes (similar to openstack cinder)
* NFS-like volumes (for filesharing)
* scratch-like storage (disposable)
* some kind of backups, TBD
With particular semantics that could be like:
* Read only storages for retrieval of public data (dumps, mediawiki), this would be parallel to the replicas as information sources.
* Read/write persistent shared storage (current scratch), this would be for sharing between users/projects.
* Read/write persistent private storage (current project home), this would be for your own tool, private
* Read/write ephemeral private storage (current /tmp, home project), this would be for temporary big file processing and such, I think currently people just use the home directory.
