oh, that`s a real bandwidth killer / i/o hog then :) think of 500gig disk with lot`s of large files , connected with 100mbit network. if many of the files are open at the time of a node going down, that will take hours then for resync. is it planned to adress this to be handled more fficiently? for example just like fr1 from enbd ?
