If you read "the right" as "not both" it's OK ;-) In HP Service Guard they used a "lock disk" (SCSI disk) as tie breaker: On split brain every node tried to "SCSI reserve" the unit, which only one node suceeded. Then (in an SBD like manner) the name of the survivor was written on to the disk (I guess), and every other node committed suicide (that's different from STONITH where external nodes kill another, AFIK). Something like that is still missing. Personal note: Bernd, I think it's time to try things now. You discussed a lot, but I still think you never tried the proposals...
