Operation To Request Attribute Not Supported Nfs4_setfacl

NFS4 ACL Management Issues and Solutions

Common Error Messages and Troubleshooting

When implementing nfs4_setfacl on NFS mounts mounted as NFS4 file systems, users may encounter the following error message:

nfs4_setfacl: Invalid argument

This error can occur when using NFSv4 over GPFS or when the NFSv3 standard was established before ACLs were introduced.

Additional Error Messages

• "NFS4_getfacl file Operation to request attribute not supported by server"
• "nfs4_setfacl -a AOWNERrxtncy Invalid argument"
• "nfs4_editfacl is equivalent to nfs4_setfacl -e Refer to the nfs4_acl5 manpage for information about NFSv4."

Solutions and Workarounds

To resolve these errors and manage NFSv4 ACLs effectively, consider the following solutions:

• Ensure that both the NFS server and client support NFSv4 ACLs.
• Use the -e option with nfs4_setfacl to edit ACLs instead of setting them directly.
• Use nfs4_getfacl to retrieve ACLs and verify their correctness.
• If using rsync, enable the --xattr option to preserve extended attributes, including NFSv4 ACLs.

By following these recommendations, you can effectively manage NFSv4 ACLs and resolve errors related to nfs4_setfacl and other related commands.
