WARNING: Circular directory structure

netappwala · ‎2015-12-17

Hi,

I have exported a volume to Linux client. Problem is that when they run "du" command on that mount point its not showing the size and it is throwing below warning messages. They can read the data without any prob.

[root@sbsaplxwmq01p home]# du -sh epub

Has anyone faced this issue?

Either turn off the .snapshot directory on the NetApp, or use the "--exclude" option of du...

du -sh --exclude .snapshot epub

cant't turn off the .snapshot directory as clients need it.

when they run du on .snapshot directory alone it is showing the size without giving any warning but the result is odd. total size of the volume what I have exported is 500g; but client can see the .snpshot directory's size alone 850g in du's output. As I posted above du is not showing the size of actualy mount point. And "df" command is showing right results.

Thanks,

Charan
