June 13, 20242 yr Hello. Moved to unRAID from TrueNAS SCALE couple of days ago, trying to wrap my head around data placement. In TrueNAS I wouldn't have to worry about it since data were automatically striped across all disks in the pool which were spinning all the time, but in unRAID I pursue a goal of setup where disks are being used only when accessed to. Now, specifics: - I have 4 x 6 TB HDDs in ZFS hybrid array, where disk3 and disk4 has been chosen for multimedia storage, - I've created a share named "mm", which is also a ZFS dataset, available for disks 3 & 4; unRAID created in on disk3, - Using "ZFS Master" plugin I've also created folders/datasets named "anime", "ebooks", "series", Now my task is to put movies on disk4, separating them from everything else, but "movies" should still be a part of root "mm" dataset, so inside SMB share named "mm" I would have anime, ebooks, tv shows and movies alike. So, question is: am I thinking straight, can it even be done? I've read abour unRAID alot, I've seen people talking they have such data structure, but I can't to graps the idea of how to do this How should I setup the share for my choice: allocation, split level disks availability and such? Thank you in advance.
June 13, 20242 yr Community Expert Unraid can only control allocation for shares (top level folders).

I had share settings look like this: Then I accessed this SMB share and created a "videos" folder: due to disk4 was empty, this new folder has been created there. Then I changed allocation back to "High-water", leaving split level as I set before (split only top level), then deleted "/mnt/disk4/videos" folder and created "disk4/mm/video" zfs dataset. In result, I have my multimedia share on disks 3 & 4, while only "movies" are going to the disk4, and all subdirectories are datasets available for snapshots. I'm gonna test how share is working, but once setup I don't expect any issues.
