* '''/cephfs/abyss/shared''': a shared directory where every user has read/write access, so your data is not secure here from manipulation or deletion. To not have total anarchy in this filesystem, please give sensible names and organize in subdirectories. For example, put personal files which you want to make accessible to everyone in "/abyss/shared/users/<username>". Be considerate towards other users. I will monitor how it works out and whether we need more rules here. If you need more private storage shared only between all members of a trusted work group, please contact me.
* '''/cephfs/abyss/datasets''': directory for static datasets, mounted read-only. These are large general-interest datasets for which we only want to store one copy on the filesystem (no separate imagenets for everyone, please). So whenever you have a well-known public dataset in your shared directory which you think is useful to have in the static tree, please contact me and I move it to the read-only region.
In addition, you can use a directory local to each host, which depending on your workload might be much faster than cephfs, but also ties you to a specific machine:
* '''/raid/local-data/<your-username>''': this is your personal home directory which you can use any way you like.
