jug_fileserver_setup

Modify file server entries in the database. These essentially create a map from host file name (HFN) URLs to real URLs. An HFN is a URL of the form hfn://machine.domain.name:/path/to/file.

Usage: jug_fileserver_setup operation options

Operations: add, modify, delete, view

Options:

• name
• server_url
• base_hfn

Example:

jug_fileserver_setup add \
  --name=test \
  --server_url=http://cassia.hep.wisc.edu:8000 \
  --base_hfn=hfn://cassia.hep.wisc.edu:/data/cmsprod

In this example, files on cassia.hep.wisc.edu anywhere under /data/cmsprod will be accessed via an http server running on port 8000. For example, the file hfn://cassia.hep.wisc.edu:/data/cmsprod/output/run1.dat will be remapped to http://cassia.hep.wisc.edu:8000/output/run1.dat.

By default, fileserver entries are automatically created for storage workers when you run them.
