Subject:	/scratch filesystem reminder

Dear Sp Users, We would like to remind users of the purge policy in /scratch, since the allocated disk quotas on the filesystem are beginning to approach capacity the system may begin to actively purge files there. "Scratch space on the SP is referred to by the environment variable $SCRATCH. This is not permanent storage: files will usually remain here for 7 days after they are created, after which time they may be purged. Note, however, that if the $SCRATCH filesytem becomes oversubscribed files may have to be deleted even before the 7 days are up (in which case the oldest files are deleted first)." If you've become accustomed to storing files other than temporary ones in $SCRATCH please look into archival storage or moving files you need to keep to your $HOME directory. If you have questions about file storage please see http://hpcf.nersc.gov/storage/ibm/#Work or contact consult@nersc.gov. Regards, David Skinner
