There are three main CLI commands that report on the status and effect of small file efficiency:
In when running the isi job report view command, enter the job ID as an argument. In the command output, the ‘file packed’ field will indicate how many files have been successfully containerized. For example, for job ID 1018:
# isi job reports view –v 1018

},
}
The second command, isi_packing –fsa, provides a storage efficiency percentage in the last line of its output. This command requires InsightIQ to be licensed on the cluster and a successful run of the file system analysis (FSA) job.
If FSA has not been run previously, it can be kicked off with the following isi job jobs start FSAnalyze command. For example:
# isi job jobs start FSAnalyze
Started job [1018]
When this job has completed, run:
# isi_packing -–fsa -–fsa-jobid 1018
FSAnalyze job: 1018 (Mon Mar 1 22:01:21 2021)
Logical size: 47.371T
Physical size: 58.127T
Efficiency: 81.50%
In this case, the storage efficiency achieved after containerizing the data is 81.50%, as reported by isi_packing.
If you do not specify an FSAnalyze job ID, the –fsa defaults to the last successful FSAnalyze job run results.
The isi_packing --fsa command reports on the whole /ifs file system. This means that the overall utilization percentage can be misleading if other, non-containerized data is also present on the cluster.
There is also a Storage Efficiency assessment tool available in OneFS. This can be run as from the CLI with the following syntax: # isi_sfse_assess <options>
Estimated storage efficiency is presented in the tool’s output in terms of raw space savings as a total and percentage and a percentage reduction in protection group overhead.
SFSE estimation summary:
* Raw space saving: 1.7 GB (25.86%)
* PG reduction: 25978 (78.73%)
