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
