eqlvolume rethin Command Syntax The command syntax is as follows: # eqlvolume rethin [--recommend | -R] [--discard-usage | -D] [--include mount-point | -i] [--exclude mount-point | -e] [--force mount-point | -F] [--group-access-file file-location | -g] [--user-name user-name | -u] The following table describes the optional command parameters. Table 41. eqlvolume rethin Command Options Parameter --recommend Abbr -R Argument none --discard-usage -D none --include -i mount-point --exclude -e mount-point --force -F mount-point --group-access-file -g --user-name -u file-location user-name Description Generates a list of volumes that appear to be good candidates for thin-provisioning, but does not rethin any volumes. Displays a list of file systems that are incorrectly mounted with -o discard, but does not thin-provision any volumes. Specifies the mount points to be thin-provisioned. If this parameter is omitted, all mount points using EqualLogic volumes will be considered for thin-provisioning. Specifies a list of the mount points that are not to be thinprovisioned. If a mount point is listed with both --include and -exclude parameters, the mount point is excluded. Causes the specified volumes to be thin-provisioned, even if they do not meet the thin-provisioning criteria defined by the ReThinRecommend and ReThinRecommendMB configuration parameters. Specifies the location of the group access file where the user names and encrypted passwords are kept. If multiple user names have been stored in the group access file, specifies a particular user identity. Examples: Analyzing Thin-Provisioning Recommendations This section provides examples showing how modifying an eqlvolume rethin configuration parameter affects the volumes that are recommended for thin-provisioning. It also shows the verbose output of the--recommend parameter showing the reasons that volumes were not recommended. Example 1: Modifying an eqlvolume rethin Configuration Parameter This example recommends a file system for volume thin-provisioning, modifies the --recommend parameter to change the minimum percentage of space required to recommend thin-provisioning, and displays a different recommendation based on the new parameter value. For more information on these parameters, see Volume Thin-Provisioning Configuration Parameters. # eqlvolume rethin --recommend --verbose Locating all mount points supported by EqualLogic targets. Logged into PS Series group 192.x.x.xy (eqlgroup2) as username grpadmin There is 1 mount point recommended for rethinning: /test04 (GroupAdmin) The following 2 mount points were not recommended for rethinning: /test05 : File system space used (2.65 GB) is greater than space used by Managing Thin-Provisioned Volumes 103
