I recently purchased a Lumin L2 with 4TB storage pre-installed and integrated it into my system using the fiber networking method shown in the second diagram at
this page. I'm using all Lumin-recommended equipment in this networking: TRENDNet switch, Startech modules, and Corning clear curve cables. In tandem with the Lumin X1, this set up provides yet-better sound than I was achieving before using ethernet connections filtered by a GigaFOILv4 just before the X1. There is yet more detail and three dimensionality and even less high-frequency harshness. I'm very pleased with the result.
However, I think that some changes need to be made to the instructions to allow greater ease of set-up of the L2. At least for me with my Mac computer (a Mac Studio with M1 Ultra running the latest Sonoma 14.3.1 MacOS), adding music files to the L2 was not simple. I struggled for a couple of hours without success trying to get my Mac to drag and drop music files to the L2 using the recommended USB connection.
I consulted my dealer. He suggested the problem might be caused by the fact that the L2 comes with NTFS formatted hard disks. Even it you install your own discs, apparently the auto-formatting function of the L2 will format the files to NFTS.
While Windows computers can read and write to NFTS-formatted discs, Macs do not allow native writing to NTFS-formatted drives. They can read files formatted in NFTS, but not write to such a drive. I suspect many Lumin users, like me, use Mac computers rather than Windows.
Nothing in the L2 instructions notes this issue. There are various third-party programs/apps which claim to allow Macs to write to NTFS. Some of these work only with Intel-based Macs, not Apple Silicon like my Mac Studio. There are articles which discuss the pros and cons of some of these third-party programs; here are links to a couple of such articles:

My dealer suggested I try the slower SMB recommendation for adding music files to the L2. This did work eventually. I was asked for a password for a "Registered User" but I was not able to come up with that password; it was not any of the passwords I use to access Lumin or my Mac computer. I instead added files as a "Guest." Doing so created a folder inside the Lumin L2 Music Server named "Public" which did not inspire confidence. But that folder did accept my music files and the L2 was able to reconstruct my music library file structure after rescanning my library. Loading 1 TB of music files took about 7 hours using the SMB method on my gigabit network.
I must say that I have never before encountered problems clicking and dragging music files to a USB drive or other external drive from my Mac. Of course, I was not using a drive formatted to NTFS.
It was only in the midst of loading the music files on the L2 via SMB that I discovered the existence of third-party apps which may allow a Mac to write to an NTFS-formatted drive. I think it would be helpful to new L2 users for Lumin to recommend a particular program or programs which would allow Mac computer users to drag and drop files to the L2. At the least, the instructions for the L2 should be modified to note the issue using the USB method with a Mac.
Have other Mac L2 users encountered such problems loading music files to the L2? If so, how did you handle the situation?
Is there a way to reformat the L2 discs to a file structure natively compatible with Macs such as ExFAT? I have to wonder why Lumin chose NTFS as the file formatting for the L2 knowing that Macs cannot write to such a file structure without the addition of third-party software.
