Description Direct Docs Feedback 2023-08-10 20:43:17 UTC

This should be clarified to add that only 'intra" (within the same server) copies are added.  There is no support for inter (between different NFS servers) copies in RHEL8.  The support for inter-server to server copies was added in RHEL9.  For more info, see https://access.redhat.com/solutions/7027105 and the bugzillas in the "Private Notes" section as well as https://datatracker.ietf.org/doc/html/rfc7862#section-1.4.1

Comment 2 Dave Wysochanski 2023-08-11 18:57:20 UTC

Hold on this update.  It's unclear to me if NFS4v.2 CLONE even works on RHEL8.  I am testing using RHEL8.8 kernel 4.18.0-477.10.1.el8_8.x86_64 and a simple 'cp' of a file mounted on localhost doesn't use anything other than NFS READ and WRITEs even though it should in theory know how to avoid these operations with CLONE.  Unless I'm missing something in terms of how this is put into use, we may need to state this NFS4.2 feature is not implemented in RHEL8 at all.
