Carp is set up correctly and operates flawlessly until multiple addresses are added and removed in a short period= of time during some testes which are run on those routers. Rebooting routers a= nd having them configure the addresses once by just adding them after reboot m= akes things work fine again. The master/master behaviour is consistent with chec= ksum issues, that is when there are different carp addresses configured on each router even when ifconfig shows identical addresses. A few times I was able= to observe different addresses shown by ifconfig but I was unable to delete ex= tra addresses due to errors as show here before. Long story short: only stress-testing by adding and removing carp addresses breaks carp. And no, it is not necessary to provide any other parameters when carp vhid = is already configured. Each extra IP address can be added to existing vhid by = just specifying vhid. --=20 You are receiving this mail because: You are the assignee for the bug.=
