i said nothing about rsync a snapshot! * rsync HOT while runnining master * stop master * rsync cold to get the copy synchron the two rsync runs because it minimizes downtime nearly to zero i do not trust any FS snapshot in this context i do not trust any documentation in this context fact is if you stop the master there are REALLY no open files and that is why i do two rsync runs, the sconed one only have to care about diffs for changed files between both ones
