(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 updates
- 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
