snapshot directory permission show as question mark.

Hello.

My customer has been using ontap 9.7p4 for NFS v3 Service ( nfs clients would be cent os7), and

they want to test restore a single file from snapshot directory. However the snapshot directory

always shows as question mark like below on root account, I can not access it anymore .

I reviewed this page

https://unix.stackexchange.com/questions/393598/linux-local-directory-permissions-as-question-marks-for-non-root but I couldn't apply execute permission to snapshot directory because the error showed that it is read only filesystem.

How can I access it?

Permissions in a snapshot-directory cannot be modified (it is read-only by design). I don't have a Linux host at the moment to test why it shows '?' But, read permission should be enough to copy the file. Have the user simply COPY the file from a .snapshot rectory to a location which is accessible (writable) to the end-user.

Following example: (steps to copy my.txt)
$ ls .snapshot/hourly.2017-05-15_1306/my.txt
$ cp .snapshot/hourly.2017-05-15_1306/my.txt .
$ ls my.txt
my.txt

Restore a file from a Snapshot copy on an NFS or SMB client:

We had the same issue on a volume where we recently enalbed snapdir-access. It turned out that we needed to umount/mount the volume from the Linux client.
