Data quota

When you have logged into the server, you usually start in your home (~) folder. Move to the root of the server (cd /) and you’ll see that is a large number of other directories. A few of these directories contain space that is assigned to your user account. Here is an overview:

Note

As of February 22nd, 2021, the old file system besfs has been superseded by besfs5 for both users and groups.

As of April 1st, 2021, workfs has been renamed to workfs2.

Path	Data quota	Max. number of files	Remark
/home/bes/$USER	200 MB	NA
/afs/ihep.ac.cn/users/${USER:0:1}/$USER	500 MB	NA	home (~)
/besfs5/users/$USER	50 GB	300,000
/ihepbatch/bes/$USER	200 MB	NA
/workfs2/bes/$USER	5 GB	50,000	no hep_sub available
/scratchfs/bes/$USER	(500 GB)	NA	max. 2 weeks

In practice, files remain on this server indefinitely. In fact, scratchfs seems to follow a less strict policy then other folders.

Warning

Do not exceed these quotas! If you do, the folder of which you are exceeding its quota will be locked by the Computing Center after a few weeks and it is quite a hassle to regain access.

Official information on the quota can be found here.
