Hi, I'm looking to break an ubuntu based NAS into two separate servers and I'm thinking of using unraid for the media part of the new servers. I've done some research into unraid and I'm pretty satisfied that it does everything I want except for one thing. Not sure what to call it, but essentially I have been using mhddfs to present the same disks as different combinations of readonly and writable to support different use cases for those disks. Essentially I have two main groups of disks - a large array (snapraid) of disks for the media, and I then have a smaller mirrored pair (zfs) of disks that hold all the metadata, background images etc for the media files. Both sets of disks use an identical folder structure I then use mhddfs to present those disks to different devices based on their use. So for example, I have one pool that is 100% read only, which is shared via NFS to all my Kodi media devices. mhddfs combines all the disks and presents a single combined view of the media with the metadata alongside it. I have another pool where the media disks are still read only, but the metadata is writable. This is used by the master Kodi instance that I use for managing the metadata. My question, is there an equivalent of this functionality in unraid, and if so what is it called so I can read up on configuring it? Thanks,
