• to be confirmed - is walrus really intended for this purpose?
• to be confirmed for walrus / warm_archive replacement

!!!Attention

    The warm archive is not built for billions of files. There
    is a quota for 100.000 files per group. Please archive data.

• command not found - not available yet for walrus?!

To see your active quota use

```console
marie@login$ qinfo quota /data/walrus/ws/
```

Note that workspaces reside under the mountpoint `/warm_archive/ws/` and not `/warm_archive`
anymore.
