du warning for netapp data ontap backend

Question

I ran the following command du --apparent-size --block-size=1 --summarize /mnt2/nfspools/_root_root_p1 PS: /mnt2/nfspools/_root_root_p1 is mount point for volume in data ontap filer.

I got the following output:

du: WARNING: Circular directory structure. This almost certainly means that you have a corrupted file system. NOTIFY YOUR SYSTEM MANAGER. The following directory is part of the cycle: `/mnt2/nfspools/_root_root_p1/.snapshot/hourly.0'

16384 /mnt2/nfspools/_root_root_p1

is there any setting I can do netapp data ontap to avoid this warning when I run du command?

Answer 1

I figured out how to avoid this warning message.

On filer volume I ran the following command:

vol options perf_test_pool2 nosnapdir on

The above command hides the .snapshot directory when accessing volume content.
