If changing the carp status, i.e. plugging in one of the configured interfa= ces (that was how I first noticed it), then the lagg0 interface went down and u= p, but carp failed to catch up on this. This happens on reboot too (but not su= re it has happened *every time*, this is a new setup). The net.inet.carp.demotion counter went to 2160 ( /240 =3D 9, which is the = number of VLANs with CARP on the lagg), but got stuck there and never came back do= wn to 0: Apr 10 20:23:00 gw1 kernel: ix1: link state changed to UP Apr 10 20:23:07 gw1 kernel: carp: demoted by 240 to 240 (send error 50 on vlan14) Apr 10 20:23:07 gw1 kernel: carp: demoted by 240 to 480 (send error 50 on vlan11) Apr 10 20:23:07 gw1 kernel: carp: demoted by 240 to 720 (send error 50 on vlan17) Apr 10 20:23:07 gw1 kernel: carp: demoted by 240 to 960 (send error 50 on vlan16) Apr 10 20:23:07 gw1 kernel: carp: demoted by 240 to 1200 (send error 50 on vlan13) Apr 10 20:23:07 gw1 kernel: carp: demoted by 240 to 1440 (send error 50 on vlan15) Apr 10 20:23:07 gw1 kernel: carp: demoted by 240 to 1680 (send error 50 on vlan10) Apr 10 20:23:07 gw1 kernel: carp: demoted by 240 to 1920 (send error 50 on vlan1) Apr 10 20:23:07 gw1 kernel: carp: demoted by 240 to 2160 (send error 50 on vlan18) Apr 10 20:23:08 gw1 kernel: carp: 10@vlan10: MASTER -> BACKUP (more frequent advertisement received) Apr 10 20:23:08 gw1 kernel: ifa_maintain_loopback_route: deletion failed for interface vlan10: 3 Apr 10 20:23:08 gw1 kernel: carp: 13@vlan13: MASTER -> BACKUP (more frequent advertisement received) Apr 10 20:23:08 gw1 kernel: ifa_maintain_loopback_route: deletion failed for interface vlan13: 3 Apr 10 20:23:08 gw1 kernel: carp: 5@vlan15: MASTER -> BACKUP (more frequent advertisement received) Apr 10 20:23:08 gw1 kernel: ifa_maintain_loopback_route: deletion failed for interface vlan15: 3 Apr 10 20:23:08 gw1 kernel: carp: 18@vlan18: MASTER -> BACKUP (more frequent advertisement received) Apr 10 20:23:08 gw1 kernel: ifa_maintain_loopback_route: deletion failed for interface vlan18: 3 Apr 10 20:23:08 gw1 kernel: carp: 11@vlan11: MASTER -> BACKUP (more frequent advertisement received) Apr 10 20:23:08 gw1 kernel: arp: 172.28.2.1 moved from 00:22:4d:6b:b1:5b to 00:00:5e:00:01:0b on vlan11 Apr 10 20:23:08 gw1 kernel: ifa_maintain_loopback_route: deletion failed for interface vlan11: 3 Apr 10 20:23:08 gw1 kernel: carp: 17@vlan17: MASTER -> BACKUP (more frequent advertisement received) Apr 10 20:23:08 gw1 kernel: ifa_maintain_loopback_route: deletion failed for interface vlan17: 3 Apr 10 20:23:08 gw1 kernel: carp: 1@vlan1: MASTER -> BACKUP (more frequent advertisement received) Apr 10 20:23:08 gw1 kernel: ifa_maintain_loopback_route: deletion failed for interface vlan1: 3 Apr 10 20:23:08 gw1 kernel: carp: 14@vlan14: MASTER -> BACKUP (more frequent advertisement received) Apr 10 20:23:08 gw1 kernel: ifa_maintain_loopback_route: deletion failed for interface vlan14: 3 Apr 10 20:23:08 gw1 kernel: carp: 16@vlan16: MASTER -> BACKUP (more frequent advertisement received) Apr 10 20:23:08 gw1 kernel: ifa_maintain_loopback_route: deletion failed for interface vlan16: 3 Then I manually removed the demote via sysctl: Apr 10 20:23:21 gw1 kernel: carp: demoted by -2160 to 0 (sysctl) Apr 10 20:23:23 gw1 kernel: carp: 11@vlan11: BACKUP -> MASTER (preempting a slower master) Apr 10 20:23:23 gw1 kernel: carp: 17@vlan17: BACKUP -> MASTER (preempting a slower master) Apr 10 20:23:23 gw1 kernel: carp: 14@vlan14: BACKUP -> MASTER (preempting a slower master) Apr 10 20:23:23 gw1 kernel: carp: 1@vlan1: BACKUP -> MASTER (preempting a slower master) Apr 10 20:23:23 gw1 kernel: carp: 13@vlan13: BACKUP -> MASTER (preempting a slower master) Apr 10 20:23:23 gw1 kernel: carp: 10@vlan10: BACKUP -> MASTER (preempting a slower master) Apr 10 20:23:23 gw1 kernel: arp: 172.28.4.129 moved from 00:00:5e:00:01:11 = to 00:22:4d:6b:b1:5b on vlan17 Apr 10 20:23:23 gw1 kernel: carp: 5@vlan15: BACKUP -> MASTER (preempting a slower master) Apr 10 20:23:23 gw1 kernel: carp: 16@vlan16: BACKUP -> MASTER (preempting a slower master) Apr 10 20:23:23 gw1 kernel: carp: 18@vlan18: BACKUP -> MASTER (preempting a slower master) (Also a bit interesting that it mentions those ARP changes.. Why would eit= her of the nodes announce the CARPed IP on the nic mac rather than the CARP ip,= at any time?) The "other" carp node (not using lagg) is 11.2-RELEASE-p7, this node with l= agg is 11.2-RELEASE-p8. The lagg'ed nic's are ix0-ix4 "<Intel(R) PRO/10GbE PCI-Express Network Driv= er, Version - 3.2.12-k> mem 0xddc00000-0xdddfffff,0xdde04000-0xdde07fff at devi= ce 0.0 on pci6" on a Supermicro A2SDi-4C-HLN4F. On both nodes, net.inet.carp.preempt=3D1, and advbase 1, advskew 100 on this node, 200 on the other. To add another dimension to this. If I set net.inet.carp.preempt=3D0 (which= I had initially), I cannot get the interfaces out of BACKUP at all: ...

Setting it to 1 again, immediately makes it master. Anyway, not sure if this is related to the ixgbe 3.2.12-k driver, or lagg, = or carp.. But I thought I'd write it down here anyway. --=20 You are receiving this mail because: You are the assignee for the bug.=
