https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D229384 Bug ID: 229384 Summary: Can't remove address from carp Product: Base System Version: 11.1-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: vegeta@tuxpowered.net I have systems running FreeBSD 11.1 where I noticed that carp goes MASTER on both routers. Those systems get their carp addresses changed very often, th= ey are Load Balancers used in testing environment where multiple changes happen every minute or so. A few times I've seen both routers on MASTER state with same IP addresses configured, or at least shown in ifconfig. Today I've seen ifconfig clearly showing different IP addresses. Router 2 shows more of them than Router 1. = When trying to add missing IP addresses to Rotuer 1 I got this error: # sudo ifconfig internal4021 inet6 2a00:X::1407/128 alias vhid 211 ifconfig: ioctl (SIOCAIFADDR): File exists Let's try to remove it then: # sudo ifconfig internal4021 inet6 2a00:X::1407/128 -alias vhid 211 ifconfig: ioctl (SIOCDIFADDR): Can't assign requested address I'm also wondering if we really need carps to compare configured addresses.= In scenarios where routers are reconfigured often by some external tool there = is a chance for a short period of config being different on master and slave rou= ters which at this moment might cause them to go MASTER/MASTER conflict. It woul= d be really useful to have this behaviour tunable. I am unsure if the bug happens also on 11.2. --=20 You are receiving this mail because: You are the assignee for the bug.=
