ZFS flushes also mark known states. If the zfs stack issues a flush and the system returns, it uses that as a guarantee that that data is now on disk. later writes will assume that the data was written and if the hard drive later changes the write order (which some disks will do for performance) things break. You can have issues if any part of the disk chain lies about the completion of flush commands. -- --- You received this message because you are subscribed to the Google Groups "zfs-macos" group.
