    Description

      What happens when a client has dirty and/or "unstable" pages in its cache, but unmount is run? I'm doing some single node testing, and it appears as though the mount does not wait for these pages to reach stable storage. Thus, the client unmounts with unstable pages in its cache, leaving the door open for these pages to be dropped in the case of a server failure. Replay is no longer possible because the client has already disconnected, right? This seems like a data integrity issue..?
