Hi, You should be able to ping the CARP IP addresses from any host (including the master), so something is wrong here.
This can sometimes be due to a routing problem. Your routing table should look similar to; 10.0.0.1 10.0.0.1 UH 0 4 - 4 carp0 10.0.0.2 127.0.0.1 UGHS 0 2 33144 8 lo0 10.0.0.2/32 10.0.0.2 U 0 0 - 4 carp0 10.0.0.3 127.0.0.1 UGHS 0 2 33144 8 lo0 10.0.0.3/32 10.0.0.3 U 0 0 - 4 carp0 Here 10.0.0.1 is the primary IP, and 10.0.0.2 and 10.0.0.3 are secondary carp IPs. Your /etc/hostname.carp file should look like; inet 10.0.0.1 255.255.255.0 10.0.0.255 vhid 1 pass carpsecurehashpasswd advbase 1 advskew 0 inet alias 10.0.0.2 255.255.255.255 inet alias 10.0.0.3 255.255.255.255 Notice the secondary IP's have a /32 subnet (which is correct despite the spurious errors in dmesg during carp fail-overs). It is having the /32 subnet on the secondaries which causes the creation of the additional route entry to lo0. What does your routing table and carp look like? Cheers, Andy.
