FTD capacity issues

For FTDs, the Volume Default Capacity is a hard limit on the amount of data that can be written to the device. The Volume Default Capacity value is an estimate of what the volume capacity is likely to be. If the value is not set correctly, the NetWorker percent-used calculation will be incorrect.

The Volume Default Capacity attribute displays on the Configuration tab of the Device properties when Diagnostic Mode (View > Diagnostic Mode) is enabled:

• To avoid accidentally filling an FTD, set the Volume Default Capacity attribute to restrict the size of the device. For example, if a capacity of 100 MB is set, then the device will be marked full when 100 MB is reached.
• Volume Default Capacity attribute must not be set to a value of more than 4 TB.
• If the Volume Default Capacity of a volume changes, the changes do not take effect until the FTD is re-created, the directory contents are deleted, and the volume is relabeled.
  NOTE:If the FTD is used before the Volume Default Capacity attribute is set, then the legacy data on that FTD must be staged or cloned to another device. Otherwise, this data will be overwritten.
