LoRS Instructions - Other LoRS Commands

1. Setting up LoRS

3. Other LoRS Commands

LoRS List

• An interesting LoRS command is lors_ls which gives details about files uploaded to the depot from your PWD. The basic command is:

 $ ./lors_ls <filename.xnd>

• To list all files uploaded from your PWD, use the * wildcard:

 $ ./lors_ls *.xnd

• A sample output:

• The details above include the read(r), write(w), and manage(m) properties, the file size (39), the depot, and the date/time when storage ends.
• If you see this type of error, make sure you use <filename>.xnd in the command line

 LORS_ERROR: -15

LoRS Refresh

• lors_refresh adds storage time to an uploaded file on the depot. You can set the storage time to:
  • the depot maximum (-m)
  • a specified extension (i.e., --add=5h OR -d 5h)
  • a specified amount of time from the present (i.e., --set=10d OR -s 10d)
  • an absolute time (i.e., --absolute=<abs time> OR -a <abs time>)
• A sample command string could look like this:

 $ ./lors_upload --xndrc dansdepot --depot-list -n -d 5m -f refresher (to upload refresher w/ 5m storage)
     (output)
 $ ./lors_ls refresher.xnd (to list the files and see when it expires)

Downloading an exnode from Lstore

• Using lstore's --get-exnode and --show-exnode options, copy an existing exnode to a file, and place it in the LoRS directory using output redirection ( > ). Example:

 $ lstcp --get-exnode --show-exnode lstore.server.name:/home/username/filepath/filename > ~/lors/filepath/filename

• Use the download command to download the exnode:

 $ ./lors_download -o newfilepath/newfilename filename.xnd
