[Lug-nuts] Windows Server and Linux CIFS Mounts

Hi Folks, This is noteworthy. I have a Windows Server 2012R2. I am using "DFS" and "Off-Line Files". * "DFS" is "Distributed File System", which among other things "exports" the designated Windows file systems as SMB "Shares". Its goal is to "accumulate" disparate filesystems into a single filesystem, like Linux does, with the added feature of duplication/synchronization of client filesystems. In particular, Windows user "profiles" are shared as "\\TCLC.org\users\Profile\<username>. * "Off-line Files" syncs a client copy with the "Share" to compensate for the "Share" periodically vanishing from transient conditions or you're traveling and not "connected". I also have a bunch of Fedora boxes. I mount my Windows user profile on "/home/cjm", which gives me everything I would see on a Windows machine. I also have a few NASes. Parenthetically, I have an ASUStore AS3204 v2, and I can heartily recommend it. Among other features, it supports hardlinks in the filesystem, which Buffalo NASes do not, and this means rSnapshot can run on ASUStore, which is pretty good news. I also have a couple of Buffalo LinkStations, which are also acceptable, but surprisingly primitive in comparison, and not without some inconvenient bugs surrounding "ownership and permissions", however they can be hacked to expose ssh and a command line. I mount the NASs on two paths, depending on the access I choose to grant. For root access, I mount \\NAS0.TCLC.org\d0 on /net/nas0/d0, for example, and there is nothing remarkable about this. For user access, I mount the NAS in the user's filesystem: /home/<user>/net/nas0/d0, which mount point is on the Windows filesystem, and that mount point is visible from any of the Windows desktops at the same level as "Desktop", "Documents", and "Downloads". Now, here's the point of this post: Windows Server can see that Fedora mount! It is not clear to me who is freelancing and extending their mandate -- "DFS", or "Off-line Files", but Windows server is aware that a Fedora box has mounted a filesystem on a Widows profile directory, and copies it, meaning files that should only be visible on the Fedora box are visible on the Windows desktop! This would simply be interesting and possibly beneficial, except this storage comes at a non-zero cost in space on the Windows Server 2012r2 disk, thanks to "Offline Files", or maybe "DFS" -- I don't know. I discovered this because I am in the middle of a project to re-factor my storage, which has become unmanageable, and I was rsync'ing big file trees around, and they started to show up on my Server! I'm not posting this as a problem for solving because I can easily work around it by simply doing my refactoring as root. No mounts within the "profile" filesystem; no volunteer files. I am posting this as an interesting observation that might be generally useful to know. Windows Server 2012r2 is spying on you! (-: -- Chris.
