Hi ! I checked without ifstate, without CARP ! ServerA #hastctl create zfshast #hastd #hastctl role primary zfshast ServerB #hastctl create zfshast #hastd #hastctl role secondary zfshast check synch on ServerA after nodirty bytes #zpool create hasthome /dev/hast/zfshast then disconnect ethernet. ServerB #hastctl role primary zfshast #zpool import -f hasthome Then reboot ServerA and connect ethernet. zpool export -f hasthome hastd hastctl role seconday zfshast Then split-brain detected appear. I made hast device realy small and checked couple of times and same result. Thanks Hiroshi
