Subject: | [Chtc-users] Clean up CHTC file space in August; Deactivation/deletion of data in unused accounts |
Greetings ALL CHTC Users, In our effort to keep filesystems performing well across CHTC systems, we are writing to ALL users for your help in cleaning out data from CHTC filesystems and to remind you of CHTC data policies: I. Clear out old data NOW from all CHTC home directory space AND the HTC Squid location.
II. After August 9, accounts will be deactivated and all data deleted for users who have not modified any home directory files for 2+ years.
CHTC Data Storage Policies - All CHTC file space should be treated as temporary storage, available ONLY for active and currently-queued computational work.ÂUsers should be remove data ASAP after a batch of work has completed. Requests for more space (e.g. quota increases) for a concurrently running set of jobs should be sent to chtc@xxxxxxxxxxx. - CHTC does not back up any user data across any CHTC file space. It is the responsibility of CHTC users to always keep backups of essential data and software in non-CHTC locations, such that it could be easily reinstated to it's in-use location on CHTC systems in the future. Data corruption and accidental deletions are real possibilities that all users should be prepared for with their own backups. - CHTC staff reserve the right to remove any user data if it is contributing to performance issues for other users and do not accept responsibility for lost or corrupted user data. In either case, the user should already have a copy of any essential data so as to easily reinstate it within CHTC systems (see previous). Lack of awareness of policies and practices will not help you to reinstate data by the time it is lost. These policies are (and have always been) echoed within the general policies for the HPC Cluster, HTC submit servers,ÂHTC Squid web proxy, and HTC Gluster. Thank you for taking action to clear out old data in a timely manner. As always, please email chtc@xxxxxxxxxxx (rather than replying to this email list) if you have any questions or concerns. Regards, Your CHTC Team
