When you deploy the CDM probe, you may notice that for some of the discovered disks/partitions, the file system value is NA.
In addition, for the Disk Total and Free fields, values are 0:
Release : 20.4
Insufficient permissions have been granted to the affected partitions, therefore CDM probe was unable to read the file system type and disk size details.
Make sure that the affected partition has sufficient rights assigned to the user that is used by the CDM probe.
