I create some ISCSI LUNS on an FAS2554 .
All the Luns are ISCSI Drives on an W2008R2 Windows Server .
But two LUNS shows in the FAS Admin Console something strange .
The Free Place from the Lun shows 0Bytes and an 100% Usage of this LUN . but in Windows the Drive is only half Full
The other LUNs shws the correct values .
When i try to reduce the Size of this strange two ISCSI Drives in Windows , the Windows Harddisk Manager hangs up .
Can someone help me .

One possibility is that when Host deleted files on the DISK , the auto re-claim on the Storage LUN (Thin-Provisioned) did not happen. If Space Allocation is set to disable than Data ONTAP does not reclaim space automatically when your host deletes data. Verify that space allocation is enabled: lun show -vserver vserver_name -volume volume_name -lun lun_name –fields space-allocation
Hope this helps.

The LUNS are Thick Provisioned . I think the Data Alocation Option is only for Thin Provisioned LUNS .
What can be the Reason , Here an Screenshot from read out the Log Files .
It looks like the LUNS are fuller then there total Size ?!?!?!
The Windows Drives are used for Backup Target for Veeam Backup , that writes Files in this Drives which was overwrite at a special Time .
In Windows Operating System the Drives are at the Moment half Full .
No One has an answer ?
