3 TB Quota on Qtree


On our cDOT System we created a 3 TB Volume and Qtree with a 3 TB Quota.

This Qtree is shared over CIFS to an Windows Server.


After mounting the Windows Explorer shows ~50 GB used space, but the volume is empty.

If we reduce the Quta limit to 3000 GB (instead of 3 TB), the Windows Explorer shows that no space is used.


On a Linux system we get the same problem after mounting the CIFS Share. 


Are there any kown problems with CIFS Shares or Quotas over 3000 GB?
