Cannot open file SMB Windows share from NetApp

Razzi — Wed, 04 Jun 2025 10:05:34 GMT

I am having an issue when I try to open a basic text file saved on a NetApp SMB server share, it throws the error "cannot open the \\netappvservername\sharename\folder\filename.txt" Make sure a disk is in the drive. I triple check NTFS permissions and so on.. I am able to access the SMB share, I can ping all NetApp interfaces... I am on ONTAP 9.1, what else can I try? Any suggestions is much appreciated.

What happens when you try \\IPaddress as the path instead?

@parisi the same results.. I also tried to restart the SMB services on the v-server but did not help.

Are you able to access \\netappvservername\sharename?

\\netappvservername\sharename\folder?

Did you get a packet capture during the failure?

What do the following commands show?

::> event log show -messagename secd*

::> event log show -messagename cifs*

::> event log show -messagename smb*

@parisi Is werid, cause I am able to access the share, I can read the contents, I can see the files, I am able to write a simple Text file, but any files that were previously stored on the share, I get an error when I try to open it such as the once I mentioned before. Also, the NTFS permissions are not showing when I try to query/ enumerate them via a Windows host.. just weird behaviour.. I opened a ticket with NetApp support, but these guys are also not able so far to figure it out. 😞

Could be a security style issue or permissions issue.

TR-4887 has some useful commands to troubleshoot ACLs (for example, vserver security file-directory show on page 86):

What's the security style of the volume? Who is the owner of the files that you cannot access? Below KB can help with troubleshooting these kinds of issues.

@DarrenJ the system is NTFS, working with NetApp support for 3 plus hours, he ended finding a disconnected in the Tiers to Azure Storage, it reads that cloud tier provider not accessible. It turns out the Azure storage config it was pointing to needs to be re-created. I submitted a ticket to Microsoft now to see if they can assist to get that fixed first.
