An Isilon storage administrator has created a 500 GB quota on a new directory called
‘/ifs/homedirs’. The administrator then begins migrating files from a Linux server through
NFS to the new directory. The migration tool returns a “Disk quota exceeded” error and fails
to complete after approximately 400 GB of files are copied to the Isilon cluster. However,
the cluster is reporting 10 TB of unused capacity. What is the most likely cause for this
error?

A.
SmartPool tier capacity has been exceeded

B.
Soft quotas have been exceeded

C.
Hard quota includes overhead

D.
Only the root can exceed 80% of quota
