The problem the tell me is that the applications need to sync all the buffers to disk just before snap is taken to insure data integrity. AFAIK, no applications support this functionality. My question to our LVM hackers was: Does the VFS layer do something like this, or even kflushd? And if so, would it be possible to have LVM call the appropriate IOCTLs to facilitate telling the apps "FLUSH NOW DAMMIT WE WANNA SNAP!@!!!" but I'm just an "Idiot Ben" and not qualified for this high-level thinking :-) > > > > That was my first thought, but see my previous message about loosing these > > messages.
