February 17, 20242 yr It seems that when Unraid uses ZFS as the file system for a disk in an array, it automatically creates and shares a volume with the same name as the directory. It then mounts the corresponding subvolume onto the directory. For example, if disk5 is using ZFS, it will have a subvolume named "asd" mounted on /mnt/disk5/asd. Similarly, if there is /mnt/disk5/qwe, it will be mounted from the "qwe" subvolume of disk5. What is the purpose of this behavior? This behavior can cause issues when trying to move files across top-level directories or create hard links.
February 17, 20242 yr Community Expert Shares are meant to be separate in the first place even without zfs, if you look at any guide about moving or hardlinking they will tell you things have to stay within the same share. With ZFS datasets allows you to e.g. snapshot one share.
