Any changes made to volume defaults are applied globally to all volumes configured for the application. Individual volume settings, where specified, override these defaults.
Steps
From the Settings page, select the Data management configuration menu.
Select Volume defaults.
Select settings:
Option
Description
Default minimum free space
This field specifies the free space threshold under which a volume is considered dangerously full. Below this threshold, volumes will be flagged in the GUI and, if enabled, email notifications will be sent. Supported options include:
Leaving the field blank, or setting the On-Off switch to Off will disable the feature.
The Total Cost of Ownership (TCO) of data on this volume in dollars per terabyte (TB) per month. Use this value to create reports that show used capacity in terms of cost per month. Leave this field blank to use the global default. Determining the actual TCO for storage can be complicated and is outside the scope of this document. Currently, this value can only be shown in $/month.
Scan exclusion pattern
Prevents DataIQ from scanning certain folders and files within the volume.
To enter an exclusion, use regular Java Regular Expressions (Regex). Use * to match any string. Use | to separate multiple exclusion patterns.
Example 1: /mnt excludes /mnt (at the root of the volume).
Example 2: */temp|*/tmp excludes every folder named .temp or .tmp anywhere on the volume.
Secondary hardlink regular expression
Files matching this regular expression in Java syntax are considered secondary hardlinks.
Secondary hardlinks are accounted for with zero bytes. This allows for more accurate reports on volumes with hardlinks.
The entire path, including the volume name, must match in order for the file to be considered a secondary hardlink. This feature is not able to be overridden in scan group and volume configuration.
NOTE Using this feature is currently incompatible with "pro-rated" hardlink accounting.
