Though I tested this on two FreeBSD/i386 SMP machines with gmirror + ggated combination. There *is* traffic going on, but it is somewhere around 50kB/s (sic! no kidding!). Also, forcefully removing the ggate0 provider (ggatec destroy -fu0), which should not impact the mirror operation in any way, panic'ed the system. I can't rebuild this test scenario on -CURRENT right now, but will do so time permitting. Maybe this is related to the gmirror deadlock I reported. But I no longer have SMP hardware to play with ...
