In our compagny network most computers are Windows computers and have no issue to mount the Netapp server volumes. And there are also a few Linux computers. We used to mount Netapp volume with CIFS without issue. But since a while we cannot access some directories. We do not know what had happened. We have tried several distributions of Linux and several version of the kernel and samba, We have always the issue; We can mount the volume without error with the following command: "sudo mount -t cifs -o username=user,password=xxxx,sec=ntlm //10.0.10.17/Data MNT", but when we list some directories, we see the error as per the kernel log below.
Examples:
List files and directories of a directory without issue:
$ ls -lah
total 291M

It happens it is impossible to enter in a directory or list its content. Example:

We have searched for this error on Google. It seems that we are not alone in this situation but we have not found any solution. Could you please help us to solve this issue?
