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.

Hi Michael,

Creation both for mode 5 and mode 6 works well in my RHEL 8.2(NetworkManager-1.22.8-3.el8 and nmstate-0.2.6-2.7.el8).

From the output you provide, it seems you are editing existing bond instead of creating now.

Could test again and provide me the whole output?

Thank you.

HI Gris
pls contact me. this is 100 reproduced on all my machines. I'm not trying to edit exist bond, I'm trying to create new.
Comment 4 Gris Ge 2020-03-09 09:40:33 UTC 
Removed the regression flag as it's not a regression issue.

The workaround is marking the slave interface as `absent` when deleting the bond.


RHV team agreed to move this fix to RHEL 8.2.1

Isn't this the intended behavior/workflow, see:

The patch fixing bug #1809330 will also got this covered.
Both bug are impacted by the same root cause.

Closing as duplicate.
