Windows Server 2012 R2 Disk usage issue
Question
-
Our file server found such a problem.
1. The D drive shows that the available space is 3.75TB
2. The Lun of the memory used by the D drive shows that the available space is only 1.1TB
3. The last day disk optimization showed 81% space efficiency.
We want to know how much data can be added to the current D drive. Why is the space displayed on Windows D drive and Storage Lun different?
The model of the storage is Dell SCv3020, we consulted Dell, but the other party told that it may be a problem with Windows space reclamation.
