The interface changes in the keepalived logs are not something keepalived is doing. My guess would be that's related to the DHCP VIP assignment feature. Keepalived is just reporting that interfaces are appearing and disappearing. My guess would be that this is a duplicate of https://bugzilla.redhat.com/show_bug.cgi?id=1957708 where the VIP is showing up on multiple nodes at once, which prevents the masters from talking to the bootstrap correctly. Unfortunately, this was opened before we had the network details captured by the installer. If this is still reproducing, can you re-run with a recent release to get new logs so we can also see the networking configuration on each node? Thanks. @ercohen Do you still hit this bug in your CI? We solved lately [1] BZ which this bug seems like a duplicate of it [1] https://bugzilla.redhat.com/show_bug.cgi?id=1957708 We hit it once. If I'll see it again I'll reopen this issue Sorry, This issue happened multiple times in our CI. Didn't see it lately OK, I'll close it, if it happens again please reopen it. Thanks *** This bug has been marked as a duplicate of bug 1957708 *** |
