Example output of the fsepartition --reorg-scan command
Checking the resulting statistics of a reorganizational scan job
After the scan job is completed, you can check the statistics gathered during the scanning process. You
can display both statistics related to individual FSE media pools and statistics related to individual FSE
media assigned to the specified FSE partition.
Displaying the FSE media pool-based statistics
To check the statistics for all configured FSE media pools:
1. Ensure that all scan jobs have completed.
2. Run the command:
Example command output:
The meaning of the columns is the following:
Displaying the FSE media-based statistics
To check the statistics for all FSE media that belong to a particular FSE partition:
1. Ensure that the scan job running on the chosen partition has completed.
2. Run the command:
You can also specify a value for the optional SlackThreshold% argument to filter out media for
which the percentage of obsolete data is not high enough, and thus less likely to need reorganizing.

NumOfMedia
Number of FSE media assigned to the media pool.
ValidData
Amount of space on the FSE media, assigned to the media pool, occupied by valid
file generations.
If the FSE media pool has not yet been scanned for reorganization, it has 0 (the
zero value) displayed in place of the ValidData amount.
Total
Total amount of space on the FSE media assigned to the media pool.
SlackSpace
Percentage of FSE slack space.
FSE slack space is the space on FSE media occupied by migrated file generations
considered obsolete by the reorganizational scan job.
