Problem
You might realize that some of your files kept in the scratch
file system have disappeared after a while.
Solution
The /scratch
filesystem is cleaned by a script on a regular basis: please check the cleaning policy on the section about scratch of the CSCS Knowledge Base.
Unfortunately, once the files on scratch
have been deleted, there is no way to recover them: scratch
is meant to keep only the temporary files needed for a run.
Please consider moving your valuable data from
scratch
to other file systems or to your local storage after your simulations are complete using the data transfer service
