PowerScale OneFS 9.2.1.0 CLI Administration Guide

Estimate possible storage savings

Use the isi_sfse_assess command to generate an estimate of possible storage savings that could be achieved by packing files.

1. To start the assessment, use the isi_sfse_assess command, as follows:

   Usage:
       isi_sfse_assess <assess mode> [process options] [sysctl options]
   
   Assess Modes:
       -a | --all                            : assess all files on OneFS
       -p <path> | --path=<path>             : assess <path> and sub-dirs
       -r | --resume                         : resume previous assessment
   
   Process Options:
       -q | --quick                          : slow mode (better accuracy)
       -f <fails> | --max-fails=<fails>      : max failures before aborting (default: 1000)
       -v | --verbose                        : verbose mode
   
   Sysctl Options:
       --max-size=<bytes>                    : max file size to pack
       --avoid-bsin[=on|off]                 : avoid cloned/dudped files
       --mirror-translation-enabled[=on|off] : convert mirrored to FEC
       --mirror-containers-enabled[=on|off]  : process mirrored files
       --snaps-enabled[=on|off]              : process snapshots
       --ads-enabled[=on|off]                : process ADS files

   For example:

   root# isi_sfse_assess -a -q -v --mirror-translation-enabled --mirror-containers-enabled

2. To interrupt processing, use the Ctrl-C keys.
   A summary of the estimation progress displays. In the background, the context of the current run-time status is saved.
3. To resume processing, use the following command:

   # isi_sfse_assess -r [-v]

   The assessment processing continues where it left off, using the same options that were provided in the original command. The -v option, for more verbose output, is the only additional option permitted with the resume option. If other options are included with the resume option, they are ignored.
