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 Andrew Beekhof 2017-09-27 09:20:07 UTC

Description of problem:

IHA got a revamp for OSP 12 and requires changes to resource and fence agents.

The changes include the splitting of fence_compute into fence_evacuate (focussed on telling nova to bring the instance back to life) and fence_compute (now exclusively focussed on ensuring the compute is listed as down in nova and removing it from the "available" queue).

fence_compute now also supports unfencing.

Ideally we need them in the next round of z-streams before OSP 12 is released.

All patches are upstream in github.

Verified , 

Instance created and evacuated on force crash of the compute node , evacuation succeed on to another compute node.
