RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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.
