space

Reports on disk space use for views, VOBs, or file-system files or directories

APPLICABILITY

ClearCase (cleartool subcommand), Attache (command)

SYNOPSIS

Report disk space used by a view or VOB:

space { -vie·w | -vob } [ -a·ll ] [ -upd·ate ] [ -reg·ion network-region ]

{ -host hostname | tag ... }
Report disk space used by file-system files or directories:

space -dir·ectory pname ...
Generate and cache data on disk space use for local views or VOBs:

space { -vie·w | -vob } -gen·erate [ -scr·ub days ] [ tag ... ]

DESCRIPTION

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 containing 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 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 by default 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 ClearCase scheduler periodically runs space with the -generate option to generate and cache data on disk space use for all local views and VOBs. See the schedule reference page for information on describing and changing scheduled jobs.

NOTE: On Windows 95 and Windows 98 machines, output from the space command is incorrect for disk volumes larger than 2 GB. The total file-system size is limited to 2048 MB, and the in-use value for the file system is wrong.

PERMISSIONS AND LOCKS

Permissions Checking: For the -update option, you must have Change or Full access in the ClearCase scheduler ACL on the host where each VOB storage directory resides. See the schedule reference page. For the -vob -generate option, you must be one of the following for each VOB: VOB owner, member of the ClearCase group. For the -view -generate option, you must be one of the following for each view: view owner, member of the ClearCase group. See the permissions reference page.

Locks: No locks apply.

OPTIONS AND ARGUMENTS

SPECIFYING THE DATA STRUCTURES. Default: If no -view, -vob, or -directory option is specified, the default is -vob. For the -generate option with no specified tag, the default is all local views or VOBs. Otherwise, with -view or -vob you must specify either -host or a tag. With -directory you must specify a pathname.

-vie·w: Reports on one or more views, identified either as those whose storage directories reside on the host specified by -host or as those indicated by the specified tags.

-vob: Reports on one or more VOBs, identified either as those whose storage directories reside on the host specified by -host or as those indicated by the specified tags.

-host hostname: Reports on all views or VOBs whose storage directories reside on the specified host.

tag ...: One or more tags, interpreted as view tags if you specify -view or as VOB-tags if you specify -vob. Each tag must be valid in the region specified by -region.

-reg·ion network-region: Specifies the network region in which each tag resides. The default is the region of the local host.

-dir·ectory pname ...: One or more pathnames, specifying files or directories in a file system.

REPORT FORMAT. Default: In a report on a view or VOB storage directory, storage items that are known to be small are not listed. (The contribution of these files is still included in the disk-use total.)

-a·ll: In addition to the default report, lists storage items known to be small, such as .pid.

DISPLAYING AND CACHING UP-TO-DATE DATA. Default: Use cached data.

-upd·ate: Computes and caches data on disk-space use at the time the command is issued, instead of using cached data, and then displays a report. The computation can take a few minutes.

GENERATING, CACHING, AND SCRUBBING DATA. Default: None.

-gen·erate: Computes and caches data on disk space use at the time the command is issued but does not display a report. The VOB or view storage directories for all specified VOBs or views must reside on the local host. If no tag argument is specified, the command generates data for all VOBs or views on the local host. The computation can take a few minutes. This option is intended to be used by periodic jobs run by the ClearCase scheduler.

-scr·ub days: Deletes cached records of data on disk space use that are older than the specified number of days. A value of -1 deletes cached records other than the one generated by the current invocation of the command, if any. Although most records are deleted, one data set per month is retained for historical purposes. This option is intended to be used in conjunction with the -generate option by periodic jobs run by the ClearCase scheduler. The default scheduled job specifies a value of 30 for the -scrub option.

EXAMPLES

Examples including wildcards or quoting are written for use in cleartool interactive mode. If you use cleartool single-command mode, you may need to change the wildcards and quoting to make your command interpreter process the command appropriately.

In cleartool single-command mode, cmd-context represents the command interpreter prompt. In cleartool interactive mode, cmd-context represents the interactive cleartool prompt. In Attache, cmd-context represents the workspace prompt.
