Job abortion

Jobs will fail if no more disk space can be allocated, or if no more files can be created because the respective quota hard limit is exceeded

Display quota information

A quota tool is delivered with the Workspace module:

$ quota
UniBE Workspace Quota report
============================
                    :  used (GB)(   %), quota (GB) |  files used(   %),      quota
==================================================================================
HOME                :        420( 41%),       1024 |      773425( 77%),    1000000

Furthermore, there is a more detailed version using the -l or --long option
$ quota -l
UniBE Workspace Quota report
============================
                    : free quota,  used (GB)(   %), quota (GB) |  files used(   %),      quota | start date(1), average quota(2)
================================================================================================================================

(0) space names starting with "SCR_" refer to the personal (usr) or Workspace SCRATCH quota.
(1) accounting period start date, The date from which the average usage is computed.
(2) file space average quota (not files), calculated by the average of messured values in the actual accounting period.

In the last example the workspace Workspace1 has 5TB of free quota, and a total of 10TB of quota (5TB additional storage requested). The start date defines the start of the accounting period and the average quota is computed as average over all datapoints starting from start date. Furthermore, the SCRATCH quota is presented starting with SCR_, where SCR_usr is your personal SCRATCH quota and SCR_ plus Workspace name the group quota of the Workspace group in the scratch fileset. Workspace SCRATCH quota is only presented if a quota is set and the quota -l option selected.

data gathering

  • Workspaces: Workspace quota information is gathered twice a day. Thus the presented data may not completely represent the current state.
  • HOME and SCRATCH: values presented are actual values directly gathered from the file system

Note: the coloring of the relative values is green (<70%), yellow (70% < x < 90%), red (>90%).


  1. Each research group can use up to 10TB of free disk storage in multiple Workspaces free of charge. Quota increase can be purchased, see Workspace Management

  2. Workspaces are meant to be active directories and no archive. Workspace are active by default for one year. The duration can every time be extended to “current date plus one year”. 

  3. Scratch quota is currently implemented per user 

  4. There is a automatic removal policy planned, but not implemented yet
