[PROBLEM] PCIE MVMe support issue

[Alfred76]

I mounted the PCIE MvMe (1T) to moode & format. But realize that the drive sizes can't extractly same as the drive. Is there any method can fully use the disk spacing? Thanks!

How did you determine there is a drive size issue?

Thanks for reply Tim! I try to drag & drop a 600G music files to the MVMe. It's said not enoguh space.

Please provide more detail for example:

1. How did you connect to the drive?
2. What application did you use to copy the files to the drive?
3. Screen shots of the error messages
4. Output from the command below

Code:

df -h /mnt/NVME/name_you_entered_in_nvme_source_screen

Using below card, PCIe port on Pi5 to connect the Nvme drive

   

Upload the files by windows though network.

The share "NVMe" that you see in Windows/Mac/Linux file managers has a size equal to the size of the /mnt/NVME directory on the root file system which is on the mmcblk0p2 partition of the SDCard. In your case it's 29.2G.

To get the max size of NVMe/Music you will need to create a manual connection to it from Windows file manager. I'm not sure what menu pick gets you to the screen that lets you "connect to a share".

Any way here's an example of the size differences on a system that has a 32G SDCard and a 1T NVMe drive.

Code:

pi@trx:~ $ df -h /mnt/NVME
Filesystem      Size  Used Avail Use% Mounted on
/dev/root        29G  3.9G   24G  15% /

pi@trx:~ $ df -h /mnt/NVME/Music
Filesystem      Size  Used Avail Use% Mounted on
/dev/nvme0n1    916G  123G  747G  15% /mnt/NVME/Music

And here's what Mac Finder reports as sizes for connections (mounts) to NVMe and NVMe/Music
