The minimum amount of information (as always) would be backtrace from
the kernel and also hastd backtrace when it coredumps. There is really
decent logging in hast, so I'm also sure it does log something
interesting on primary or secondary. Another useful thing would be to
turn on debugging in hast (single -d option for hastd).

The best you can do is to give me the simplest and quickest procedure to
reproduce the issue, eg. configure two hast resources, put ZFS mirror on
top, start rsync /usr/src to the file system on top of hast and switch
roles. The simpler the better.
