The ucarp-up script on the secondary node is executed, but it fails because of the still running secondary worker process (Secondary process for resource test is still running after 30 seconds). Is the secondary process expected to end automatically, when the primary process fails? > > Thanks for your help Does it work correctly if you use the built-in carp(4) + devd(8) instead of the port for ucarp? That will narrow down whether it's an issue with ucarp or with hastd(8). Personally, I prefer to use the tools that ship with FreeBSD, as it gives it a more integrated feel. http://blather.michaelwlucas.com/?p=241 Has some pre-configured scripts for hooking into devd.conf(5) to glue together carp(4) and hastd(8). Works for ZFS and UFS. -- Freddie Cash fjwcash@gmail.comhome | help
