PowerScale OneFS 9.3.0.0 CLI Administration Guide
Assess deduplication space savings
You can assess the amount of disk space you will save by deduplicating a directory.
-
Specify which directory to assess by running the
isi dedupe settings modify command.
The following command configures SmartDedupe to assess deduplication savings for /ifs/data/archive:
isi dedupe settings modify --assess-paths /ifs/data/archive
If you assess multiple directories, disk savings will not be differentiated by directory in the deduplication report.
-
Start the assessment job by running the following command:
isi job jobs start DedupeAssessment
-
Identify the ID of the assessment report by running the following command:
isi dedupe reports list
-
View prospective space savings by running the
isi dedupe reports view command:
The following command displays the prospective savings recorded in a deduplication report with an ID of 46:
isi dedupe reports view 46
