[SOLVED] 9.1.x: NVME samba share size wrong when mounted on Windows

[Matter]

Hey community,

I've been using moode since version 5.x. After testing various commercial streamers I am super happy to have found a setup that offers what I like and need. Thank you very much Tim and team!

Recently, I moved from a RPi4 setup to the Pi4 Compute Module & official IO board with an NVME disk (via IO board's PCIe slot) as internal music storage. The previous micro SD card via USB adapter had become too small, so I decided to go for an 4TB SSD which could also function as a small file server for this and that. Moode version is 9.1.4, fresh setup but also happened with a system clone of my previous Pi4 setup.

Here comes the trouble: 

• NVME disk is installed, formatted and mounted via moode's "Local NVME Drives" section of the Library. Listed as "3600 (/dev/nvme0n1, ext4)", where 3600 is the name or identifier of the disk.
  
• mount states /dev/nvme0n1 on /mnt/NVME/3600 type ext4 (rw,nodev,noexec,noatime,nodiratime) - just as expected
  
• df -h reports 3.6T size and 3.4T available on /mnt/NVME/3600 - OK
  
• Samba filesharing is enabled. Using default NVME config entry of /etc/samba/smb.conf
  
• When mounting NVME share on Windows, it reports a total size of 14GB and 9.6GB free size - which is the actual size of the Pi's OS SD card.
  -> I can only copy 9GB of music to the share via network because Windows thinks the drive is full. So I'm stuck.
  

I can copy ~0.9TB of files from an USB disk connected to the Pi directly to /mnt/NVME/3600 via terminal. When I mount the share the fies are accessible and Windows shows total size of 900GB with 9GB left. Files play as expected, I can delete, rename them on the share but I can't copy more tha 9GB of new fies over. Stuck again.

When I tried to mount the NVME disk via /etc/fstab (after unmounting it in the Library section) moode didn't come back after the reboot. Since the system runs headless, I had no chance to debug.

Maybe this is a Samba settings or config issue. Or maybe I should mount the NVME disk via fstab right away instead of using moode Library's option.

Does anyone have an idea or has gone through a similar issue with a RPi5 setup with NMVE ssd? 

Cheers,
Matt

Try editing /etc/samba/smb.conf and add a share block like below then restart SMB (Samba)

[NVMe3600]
comment = NVMe 3600 Mount
path = /mnt/NVME/3600
read only = No
guest ok = Yes

Then connect to the "NVMe3600" share from Windows and see if the correct size is reported.

Creating an extra entry in smb.conf solved the problem. Size in Windows is now reported correctly. So simple...

Thank you very much, Tim!

Kind regards,
Matt
