The issue involves a user on an Ubuntu client (a Linux-based system) who is unable to create files on a Nutanix Files share configured to support both Windows and Linux clients. Since Ubuntu typically uses the NFS protocol to access file shares, the problem is likely related to the NFS configuration on the Nutanix Files share. The correct action is tomodify NFS Client Access to read-write, as the current setting may be restricting the Ubuntu client to read-only access.
TheNutanix Unified Storage Administration (NUSA)course explains that “Nutanix Files supports NFS for Linux clients, and administrators can configure NFS Client Access settings to control permissions, such as read-only or read-write access, for specific clients or subnets.” If the NFS Client Access is set to read-only for the Ubuntu client’s IP or subnet, the user would be able to read files but not create or modify them, which matches the described issue.
TheNutanix Certified Professional - Unified Storage (NCP-US)study guide further states that “troubleshooting access issues for Linux clients on Nutanix Files often involves verifying the NFS Client Access settings, ensuring that the client has read-write permissions to create or modify files on NFS shares.” The administrator should check the NFS export settings for the share and update the client access rules to grant read-write permissions to the Ubuntu client’s IP address or subnet.
The other options are incorrect:
Allow simultaneous read access to same files: This setting is relevant for managing concurrent access to files (e.g., in SMB environments) but does not address the Ubuntu client’s inability to create files via NFS.
Update the blocked file types in the file server: Blocked file types prevent specific file extensions from being stored, but the issue is about creating files, not a specific file type being blocked.
Add NTFS permissions for the user account: NTFS permissions are relevant for SMB shares used by Windows clients, not for NFS shares accessed by Linux clients like Ubuntu.
The NUSA course documentation emphasizes that “for Linux clients experiencing permission issues on NFS shares, administrators should review and modify the NFS Client Access settings to ensure read-write permissions are granted, resolving issues like the inability to create files.”
