PowerScale: macOS Ventura Clients Experiencing Issues Accessing Files Over SMB

Apple has identified an issue with client machines that recently upgraded to macOS Ventura. They may experience unexpected behaviors when attempting to create or access files over SMB protocol. In some instances of the field, it was observed that a client goes to a share and finds all files in a Read-Only state when they had sufficient privileges to do more.

In some instances, permissions at the share-level must be adjusted further as the client operating system blocks the open operation over SMB protocol.

A code issue on the client operating system was identified that Apple has recently addressed.

The permanent fix is for macOS Ventura clients to upgrade to version 13.3. When this cannot be done in a timely fashion, Apple has provided the following workaround. This must be performed on the impacted client and requires a remount.

Workaround:

1. Unmount the share on the client.
2. Create the following file on the client, adding the parameters as follows:

sudo touch /etc/nsmb.conf echo "[default]" | sudo tee -a /etc/nsmb.conf echo "file_ids_off=yes" | sudo tee -a /etc/nsmb.conf

3. Mount the share on the client.

If the workaround is completed, the share-level permissions for the user must be changed to Full Control (if they have change permissions instead). This is because there have been instances identified where having change permissions at the share still result in the open operations being blocked over protocol by the client operating system.
