Omega2 Pro don't mounting USB storage



  • Hello, my Omega2 Pro isn´t enable to mounting USB storage.
    Can´t find /tmp/mounts/ or USB-A1
    When I used Transmission I get an error message:
    "No space left on device"

    Please, any help!



  • @Lino-Amorim On OpenWrt 18.06 based Onion firmwares - for example an Omega2 Pro FW
    the auto-mount point of a USB pen drive (/dev/sda or /dev/sda1) is
    /mnt/sda or /mnt/sda1 respectively.

    See also "/tmp/mounts/" file does not exist or removed when upgrade firmware



  • Thank you!
    Do I have to replace "USB-A1" for "sda1" in the set ups of Transmission?...
    Or just mounting the USB storage with "/mnt/sda1" ?



  • @Lino-Amorim If the output of your mount | grep /dev/sda command is:
    /dev/sda1 on /mnt/sda1 ...

    then change /tmp/mounts/USB-A1/ to /mnt/sda1/ in transmission's configuration uci commands - for example:
    uci set transmission.@transmission[0].download_dir='/mnt/sda1/downloads'



  • Thank you, very much!
    All done!
    Last question:
    What is the command line to see the informations about the USB storage?



  • opkg install usbutils
    lsusb -v



  • @Lino-Amorim I think these are useful commands:

    ls -l /dev/sd*
    mount without parameters or mount | grep /dev/sda1
    df -hT or df -hT | grep /dev/sda1
    ls -lA /mnt, ls -lA /mnt/sda1, ...

    Some "technical" info:
    fdisk -l
    lsusb -v

    If you want to use the lsusb command: enable the second (2nd) line in the '/etc/opkg//distfeeds.conf' file and
    opkg update
    opkg install usbutils


    For example:
    Omega2+ FW v0.3.2 b232 with 8GB MicroSD card and 8GB FAT32 formatted USB pen drive with Expansion Dock
    This is a "fake" Omega2 Pro - using FW omega2pro-v0.3.2-b232.bin
