    alias CARP on re0 from rc.conf results in boot stopping from progressing

    Hi all, I'm trying to add a CARP alias to my up to date 13.3-RELEASE setup. It works fine when it's done after the system is up, using: ifconfig re0 inet vhid 1 pass password alias 192.168.178.33/24 but if I try doing it at boot time via rc.conf as: ifconfig_re0="inet 192.168.178.35 netmask...

    CARP stopped working after upgrade from FreeBSD 13.2 to FreeBSD 14

    After upgrading from from 13.2 to 14.0, CARP stopped working as expected. For one, no matter what I do with manually setting the state or adjusting the advskew, it doesn't work as expected. The same with the preempt kernel parameter. I have tried both unicast and multicast peer settings. Here...

    CARP + IPv6 host does not respond to neighbor solicitation multicast

    I noticed that on my CARP hosts (three pairs, six total) ssh to the local address of the current master took a long time. Turns out that it was timing out trying IPv6 and falling back on IPv4. ssh -4 always works right away. While debugging I realised that the CARP host saw neighbor...

    Build Router HA Cluster with BGP Support

    Hello, i want to build a Router HA Cluster with two hardware servers. Each Node should have one IP per subnet and the default Gateway IP of the subnet would be a CARP IP bound to the active node. So far this seems to be straight forward and would work great for static routing. The router...

    ZFS ZFS SLOG Mirror split across HAST and local device

    So, I have been experimenting with methods for providing "clustering" on ZFS for a while now and I recently purchased a Supermicro 6036ST-6L Shared Storage Bus system. It's provides an interesting opportunity as both nodes in the host can share the storage via SAS, and the SAS topology seems...

    CARP puts the interface in promiscuous mode

    Hi, I would like to use CARP, but noticed that when CARP is configured on an interface, promiscuous mode is enabled. I had to check the source and sure, these lines are included: if ((error = ifpromisc(ifp0, 1))) return (error); I'm not that eager to have promiscuous mode enabled for...

    Other ctl HA vs HAST for vSphere SAN - are both necessary?

    Hi, I'm looking at setting up a storage area network for ESXi/vSphere, and I've been looking at all my options. One thing I came across recently while looking at HAST was that ctl itself has its own HA functionality. From ctl: +o Support for multiple ports, initiators, targets and...
