-===== Nuclear, Particle and Theorerical ​Physics =====+2020-06: I am currently working on some kind of system to keep track of usage and do some minimalistic data management. More information will come. 
 +===== Basic rules ===== 
 + 
 +Please follow these rules to keep the storage tidy. 
 + 
 +  - Whenever you need to move data to one of the shared folders below,\\ **create a folder with a name than can be understood by everyone** and put the data in there. 
 +  - If the data has been generated by you or if it is for your exclusive use, **create a folder with your username** to accomodate the data. \\ In this way you keep your data away from unwanted people and you can set all the permissions you want on it. 
 +    * Data found outside a folder named after a user it is a good candidate to be deleted. Of course there can be exceptions when needed. 
 +  - Remove data that you don't use, for example from the ''​scratch''​ folders. Be kind to your colleagues! storage has a cost. 
 +  - Follow the instructions at [[aurora_cluster:​moving_data|Moving Data to and from the Aurora cluster]] when you start moving data around.

 +==== GRID storage ==== 
 + 
 +Lunarc hosts a GRID storage for ATLAS. Currently we are migrating from a 20TB storage to a 100TB. 
 + 
 +The local storage GRID name is  ''​ SE-SNIC-T2_LUND_LOCALGROUPDISK ''​ 
 +   
 +One can interact through it using the Rucio client. It cannot be mounted directly on the cluster. Data can only be moved to and fro. Access is restricted to **ATLAS** members.
  
-There are two storage servers installed for the exclusive use of particle physics. +Details on how to access this storage are at this page: http://www.hep.lu.se/grid/​localgroupdisk.html
-The recommendation is to use these instead of /project/hep/nobackup so to give space to the other users of it.+
