How to organize network storage with disks in different parts of Russia?

Question

System administration

There are two offices. One in Moscow, the other in Barnaul.
It is necessary to create one common partition from disks that are located in both cities (something like a network storage), but so that the files that belong to Barnaul are physically located on the Barnaul disk, and the files that belong to Moscow are physically located on the Moscow disk.

Answer 1

On Linux

Answer 2

We put the storage in an accessible place, where the access speed from Barnaul and Moscow is the same ... Let's say in Germany.
We keep our stuff there, and between the servers and the storage we set up data synchronization.
The first thing that came up.

Answer 3

If you install windows on the servers, then the scheme is as follows:
1. Create a ball on a server in Moscow (where Moscow's documents are located).
2. Create a ball on the server in Barnaul (where the documents of Barnaul are).
3. Spheres are added to the DFS space, map it to clients as a network drive.
By Linux.
1. The scheme is the same, but instead of DFS we use NFS (but it will be slow with Windows, not a very nfs client in Windows).
2. We use DFS in SAMBA, let me be corrected, it seems that it is possible to create a standalone dfs root.
PS The speed of opening remote files will be limited by the connection speed.
If there is a domain structure, it is better to use it on windows servers.

Answer 4

On the previous question "so that the files are logically in the same directory", did it just work out?
