Unraid User Vs User0
The user vs user0 distinction in the operating system is based on whether you have a root file or a file with a defined root. As a result, you can’t mount the unraid volume in the first place. However, if you mount a directory in the first place, the second user will have access to all files on the disk. For example, if you have two partitions, one is named unraid1 and the other is named user0. Then, all of the subdirectories are under /mnt/, and the virtual folders /mnt/user and ‘user0’ are the respective users.
To merge data from all the drives, you should create a partition in /mnt/cache/data. Your SSD is mounted to /mnt/cache/user/data. When you run an app, it will pick a file from both the Array and the SSD, even if it has a duplicate of the same file. As a result, the file in Array is used when you run the app in the system.
The data from all drives on the Unraid machine is merged in the Unraid user’s user profile. When you use an app, it will access /mnt/cache/data. When you use an application, it will access the SSD. When the system needs a file, it chooses the one in the Array or the one on the SSD, even if the latter has a duplicate file.
As far as how a disk partition works, the Unraid user is the only one who has access to data from the other drives. In a typical configuration, an SSD is mounted on /mnt/cache/data and an Array is mounted in /mnt/user/data. The system then chooses the SSD when it requires a file. The system also picks the one in the Array, and ignores the SSD when there is a duplicate file on the Array.
As a result, the data from all drives on an Unraid machine is merged. As a result, the user is able to access the data stored in a file on the Array. Similarly, the system can access the SSD’s data. When an Array is used, the data on the Array is split into multiple folders. Its files are not on the SSD, and vice versa.
The Unraid machine merges data from all drives. As a result, the user will get the same data on both drives. If an SSD is mounted on /mnt/cache/data, the Unraid machine will access the file on the Array. In the same way, the data from the SSD will be duplicated in the Array. In this way, the data from the Array is merged with the data from the SSD.
The Unraid machine uses all the data from all the drives. The SSD is mounted on /mnt/cache/data. The Array will be mounted to /mnt/user/data. The SSD is used for storage by apps. When the system is trying to access a file, it picks the one in the Array. Therefore, the SSD is duplicated in the SSD.
The Unraid user’s data on the Array is merged with the data from the SSD. In this way, the Array will be able to handle all the data. But the SSD isn’t mounted in the Array. Its data will be on /mnt/cache/data, where apps access the Array. The Array will be used to mount the other drives.
By default, the Unraid user will have a single drive. The data from the SSD and Array drives are merged in the Array. The SSD is mounted in /mnt/cache/data. The Array is mounted in /mnt/user/data. The SSD is used for storage by applications. Whenever the system accesses a file on the Array, the OS will choose the SSD, which will be the original file.
