Carter Scratch Transfer Tool

September 30, 2016

On September 27th, 2016, the Carter cluster scratch filesystem, which had been suffering from numerous issues, was replaced by an entirely new system. Unfortunately, in order to put the new system into place quickly, it was not possible to copy over all the existing files to the new system. However, these files are still available to all users for a period time.

You will find your $CLUSTER_SCRATCH directory on Carter is now a new empty directory. Your previous files may be accessed by using a new transfer tool deployed on Carter today. We are trying to keep the old scratch filesystem available in this way for a few weeks to allow for file transfer.

To run the tool, log into Carter as usual using SSH or ThinLinc. Once on Carter, run the command:

/usr/site/rcac/bin/carter-scratch-transfer

This will copy all of your files from the previous scratch system into your new scratch directory under a directory called "carter-warp-files", or "$CLUSTER_SCRATCH/carter-warp-files".

Execution of this command may take some time depending on how many files you have. If you have a large number of files it may be helpful to launch the command from a ThinLinc session to allow the transfer to run unattended.

If you need assistance in transferring files, please contact us at rcac-help@purdue.edu and we can provide assistance and instructions more specific to your situation.
