Big transfert don't work

    OMV is installed on a very tiny computer (intel atom and 1 Go).


    With transfert > 1Go, the transfert stop. and i must reboot.


    before, I have a message

    Code
    The system monitoring needs your attention.

Host:        OMV
Date:        Sat, 13 Sep 2025 17:50:02
Service:     OMV
Event:       Resource limit succeeded
Description: mem usage check succeeded [current mem usage = 89.6%]

    With, "top" i can see that memory is full. but swap is not used.

    I try to change swapiness parameter to 20. not better.

    Here is a part of the log :

    Hi,

    What is 1Go?

    Intel Atom? Which one? Something like an N170 processor?

    If it's that kind of computer, you'll need to be very patient, because they're really, really slow. My Raspi 4 is much faster.

    I love inxi. Show me

    Code
    inxi -Fz

    You'll probably have to install inxi first

    Code
    sudo apt install inxi

    Hi

    What is 1Go? : 956.00 MiB

    Intel Atom? Which one? Something like an N170 processor? :Intel(R) Atom(TM) CPU D425 @ 1.80GHz

    I mainly use it as a file server and it plays its role well with a transfer speed greater than 100Mb/s with very low consumption.

    I know "GB" as an abreviation for GigaBit.

    You CPU is hell on earth, it is the bottleneck for everything. My Raspi4 is more than 4 times faster!

    You have a swap-Partition. But do you use it? Please show

    Code
    cat /etc/fstab

    It appears you're running the "system FS" ("/") from a USB drive. This can work, if it only does "system" stuff. Since none of the other partitions are mounted, I'm guessing the copy job you're trying to run also uses this USB drive as the source or target? If that happens to be the case, please check if your USB drive isn't too I/O limited to do the job:


    Code
    lsusb -v


    If this drive runs at 480MB/s (USB 2 speed), the transfer on a 1GB/s (=1024MB/s) network card could saturate the source drive, which in this case is also the system drive. Unhappiness is virtually guaranteed, if this assumption is true.

    You can verify if my assumption is correct super easily: Try a transfer from a different drive. Ideally you could use one of the Toshibas for testing? For convenience, you can try another USB drive connected to another USB port as a data source, too.

    The swap is in the fstab. Besides, top shows that it is used but so little

    The system disk is on USB, but it's not a flash drive, but an SSD. I have two disks. They're mounted on /media.

    My problematic copies are made to these drives.
