SCRATCH Filesystem

The SCRATCH filesystem (mounted under /scratch directory) is subject to the 30 day file purge rule. Any file that has not be accessed in over than 30 days will be purged. In order to help users identify old file we generate a file, one per user, every morning. This file /usr/local/var/lustre_stats/$USER.over30d.files.lst contains a list of all the files that haven't been accessed in over 30 days. This file provides the full path, last accessed date and file size of the files. The filesystem updates the file access time once in 5 days. The last accessed time in the file is approximate and could be off by up to 5 days. The purging systems understands this and will make sure the access time falls within the purge window before deleting the file. During the purge only files are deleted, the directories will be left alone. Please let us know if you have any questions.
