As part of the July 20th Gilbreth Maintenance, home directories on Gilbreth will be separated from the legacy home filesystem shared with several other clusters. This move will allow Gilbreth to grow and maintain home directory storage for years to come.

Everyone will be given a new, empty, home directory on Gilbreth with a 25 GB limit. Please use one of the following methods to copy files from your current legacy home directory to your new Gilbreth home directory:

• Globus: A new Globus endpoint, “Purdue Gilbreth Cluster - Home Directories”, has been created for your new Gilbreth home directory. You can select and transfer files and folders from your legacy home directory to your new Gilbreth home using Globus. Here is a direct link to the Transfer Gilbreth Home Directory Files page. Globus does not normally show hidden files and folders such as “.bashrc”, so you will want to enable the “Show Hidden Items” option to allow you to see and transfer these configuration files (the eye-in-folder icon under the “hamburger” options menu). Still more information on how to use Globus may be found in the Gilbreth User Guide - Globus Transfer Section

• copy-rcac-home: This is a custom tool which will transfer most of your current legacy home directory contents to your new Gilbreth home directory. You need to log in to a Gilbreth front-end host and run copy-rcac-home in a terminal. For more details, see the Gilbreth User Guide - copy-rcac-home Section.

• Unix tools: You may also use typical command line utilities such as cp and rsync to copy files from your legacy home directory to your new Gilbreth home directory. Your new Gilbreth home directory is already available under /home-new/$USER. After the maintenance, your legacy home directory will be available under /home-old/$USER and will remain available for several weeks after the transition.

On July 20th, your home directory on Gilbreth will switch from the current legacy home directory to the new Gilbreth home directory. If you have not copied your shell configuration files or research work files prior to this, you will need to then do so in order to continue using Gilbreth as you had been. After August 31st, your old legacy home directory will no longer be available on Gilbreth.

If you use Windows to access your Gilbreth home directory, following this transition you will need to update your drive mapping as follows:

• Windows: \\home.gilbreth.rcac.purdue.edu\gilbreth-home
• MacOS or Linux: smb://home.gilbreth.rcac.purdue.edu/gilbreth-home
