Hi @relan,
Congratulations for this great project and for making exfat filesystem available on Linux.
There might be an unstability issue when using
exfat
+ Samba. Here is how to reproduce on a Raspberry Pi4.Connect a USB3 external HDD to a RPi4, that you know being fast enough (temporarily create a
ext4
partition on it and dodd if=/dev/zero of=/mnt/a/test bs=1M count=1000
to make sure it's at least 50MB/s)Now create an
exfat
partition on the same disk, and create a read+write Samba share on itFrom any other computer (use an ethernet cable and not WiFi since WiFi would be a bottleneck), Windows for example, go to the shared folder and copy a large file (e.g. 2 GB) to this Samba share. Direction: Windows => Rpi4 exfat partition
The Windows Explorer will start freezing / crashing. On the SSH RPi side, even
ls
is unresponsive. Once I gottop
working and very high CPU was used by FS related process.Do you have any idea?
This doesn't happen with NTFS. See also https://raspberrypi.stackexchange.com/questions/118654/how-to-mount-a-veracrypt-container-on-a-rpi-with-optimal-performance/118693#118693
