I have a somewhat interesting scenario. I have an RBD of 17TB formatted using XFS. I would like it accessible from two different hosts, one mapped/mounted read-only, and one mapped/mounted as read-write. Both are shared using Samba 4.x. One Samba server gives read-only access to the world for the data. The other gives read-write access to a very limited set of users who occasionally need to add data.
However, when testing this, when changes are made to the read-write Samba server the changes don't seem to be seen by the read-only Samba server. Is there some file system caching going on that will eventually be flushed? Am I living dangerously doing what I have set up? I thought I would avoid most/all potential file system corruption by making sure there is only one read-write access method. Thanks for any answers. Brad
