Omega2 Pro don't mounting USB storage

Lino Amorim

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

Lino Amorim

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" ?

György Farkas

@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'

Lino Amorim

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

György Farkas

@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
