Samba share of external drive.

Efriim

Retropie 4.4 + update 4.4.12
Rpi3B+ with generic PSU and MegaPi case
USB Drive is 16gb Sony flash, formatted in windows to 16gb fat32,16kb blocksize.
Fstab mounts to a folder "RetroPie/memorycard" [pi.pi rwxr-xr-x (755)] with the following:
UUID=1A92-F7C1 /home/pi/RetroPie/memorycard vfat defaults,user,rw,uid=pi,gid=pi 0 1
Samba is active with writeable okay, default mask, force user = pi.

The mount is okay, and the share is active and works for most read and write.
The problem is when transferring a large file 500mb+ to the USB drive over network ethernet, the transfer times-out unable to complete, losing sustained access, the transfer calculation never completes.

The ethernet cable is connected directly pc to pi. I'm considering there is either some sort of filesystem scheduler (fat32 mount on EXT4 dir) or network (ethernet configuration pi side) problem.
Maybe it is the blocksize(16kb) or mount options, in the RetroPie dir.
Transferring onboard from the sdcard to the usb media works without fail.

@Efriim Is your OS also updated ? There have been some bugs with the ethernet adapter on the 3B+ that have been solved with kernel updates.
Did you try the Wifi instead of ethernet ?

Efriim

@mitu
No, I think updated the OS round 4.4.11
Can you give me the command to call just the OS update from the package manager?
Usually I will just update all packages.

I tried the wifi just now it is the same. It is specific to the USB drives samba share 300mb+ file transfer.
It will say it is calculating the time for about a minute, then

There is a problem accessing \\10.0.0.2\memorycard

Make sure you are connected to the network and try again.

If you answered yes when asked to update the OS packages in the RetroPie-Setup update process, then you already have the latest versions of the kernel and firmware.

Does it work if you copy the file to the roms folder ?

Before you start the transfer, run (from a SSH session or terminal) dmesg -c. Start the transfer, then get the error. Run dmesg and see if you get any error messages.

@mitu
The roms folder share does not share this problem; it is only the memorycard usb share.

dmesg turned no error.

@Efriim Then the problem is the Samba share and not the Pi. Restart Samba after you the USB is mounted and then re-try to copy the file to the share.
