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 of problem:
Resource of aws-vpc-move-ip leaves a static routing entry even after the resource has failed over to the other cluster node.
Version-Release number of selected component (if applicable):
This issue has been observed on RHEL 8.0 with the following version.
Name : resource-agents
Version : 4.1.1
Release : 33.el8
Architecture : x86_64
How reproducible:
Reproducible in AWS environment
Steps to Reproduce:
1. Create a resource of aws-vpc-move-ip for OverlayIP.
2. Wait till a static entry is created in the routing table. For example the virtual hostname is r8s4ascs.
[root@rhel8-node1 ~]# route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
default ip-10-0-1-1.ec2 0.0.0.0 UG 100 0 0 eth0
10.0.1.0 0.0.0.0 255.255.255.0 U 100 0 0 eth0
r8s4ascs 0.0.0.0 255.255.255.255 UH 100 0 0 eth0
3. Move the resource to the other cluster node, note that on the previous node the static route is still in the routing table.
Actual results:
The previous node still has a static route in the routing table
[root@rhel8-node1 ~]# route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
default ip-10-0-1-1.ec2 0.0.0.0 UG 100 0 0 eth0
10.0.1.0 0.0.0.0 255.255.255.0 U 100 0 0 eth0
r8s4ascs 0.0.0.0 255.255.255.255 UH 100 0 0 eth0
Expected results:
The route entry should be gone.
