I got 2 servers with CARP enabled. One is MASTER, second - BACKUP. CARP is for HA of running some service on that servers. All works fine, but today I've got interesting case: Service was not responding for 5 minutes. Can't tell more details because it was said by not IT guy. Okay, I went to check logs on master and backup servers. All was fine except dmesg and messages: Master server has no recored in messages for about 1 hour. But on slave server I saw that: Oct 20 12:15:00 carp-backup kernel: arp_rtrequest: bad gateway 1.1.1.5 (!AF_LINK) Oct 20 12:15:00 carp-backup kernel: arp_rtrequest: bad gateway 1.1.1.6 (!AF_LINK) Oct 20 12:15:00 carp-backup kernel: arp_rtrequest: bad gateway 1.1.1.9 (!AF_LINK) .................. Oct 20 12:49:58 carp-backup kernel: arp_rtrequest: bad gateway 1.1.1.5 (!AF_LINK) Oct 20 12:49:58 carp-backup kernel: arp_rtrequest: bad gateway 1.1.1.6 (!AF_LINK) Oct 20 12:49:58 carp-backup kernel: arp_rtrequest: bad gateway 1.1.1.9 (!AF_LINK) Total about 300 records. Can anyone comment something about it? What was that? Backup server was loosing connectivity with Master server? In sysctl.conf I've got only net.inet.carp.preempt=1.Now I tuned log to net.inet.carp.log=2. This should log carp info messages. Am I right about loosing connectivity between master-backup servers or there can be another reason?
