space

The space command displays data on disk space use for views, VOBs, or file system files or directories. Reports are organized by disk partition, with disk-use statistics listed both in absolute units (megabytes) and as a percentage of the capacity of the disk partition that contains the storage directory.

• The report for a view includes view-private storage and administration data, as well as the space occupied by the view database. For a snapshot view, the report does not include the space occupied by the snapshot view directory tree. To display that information, use the –directory option and specify the root directory of the snapshot view. The information reported varies according to the availability of information on the view, as follows:
  • If the view resides in the default region of the host on which space is run, the view tag is listed.
  • If the view does not reside in the default region of the host on which space is run, the view tag and its region are listed.
  • If the view is not found in the registry, but the VOB database has a record of its location, the view's UUID, host, and host path are listed. Views in this state are likely candidates for the rmview –uuid command.
  • If the view is not found in the registry and the VOB database has no record of it, the view's UUID is listed. Views in this state are also likely candidates for the rmview –uuid command.
• The report for a VOB includes disk use information for the VOB database and for each storage pool. Among other statistics, it includes information on backup VOB databases left behind when reformatvob was used.

With the –view or –vob option, space uses previously generated, cached data for a view or VOB. The –update option generates fresh data and updates the cache before displaying the report. With the –directory option, space does not use cached data.

The –generate option is intended for use by scheduled jobs. By default, the scheduler periodically runs space with the –generate option to generate and cache data on disk space use for all local views and VOBs. For information about describing and changing scheduled jobs, see the schedule reference page .
