Filesystem root low disk space

[jcwilli5]

Im running the NETDEV SUPPORT version with my PEAK adapter on Ubuntu 18.04 to capture CAN packets. I'm using the following commands:

sudo modprobe peak-usb
sudo ip link set can0 up type can bitrate 250000
sudo ip link set up can0

After running this for a couple weeks on my PC and no other programs I get "Filesystem root low disk space". Other forums suggest that the logs are being stored somewhere. Any ideas on how to fix this?

Hello,

One would assume that you do more than:

Code: Select all

sudo modprobe peak-usb
sudo ip link set can0 up type can bitrate 250000
sudo ip link set up can0

to capture CAN traffic, so can tell us the exact command (with parameters) used
for capturing?

Furtermore, how much disk-space is there to begin with?

Best Regards

I'm running a basic logging script in an azure container on the Ubuntu PC:

Code: Select all

import logging
import time
import can
import j1939

logging.getLogger('j1939').setLevel(logging.DEBUG)
logging.getLogger('can').setLevel(logging.DEBUG)

def on_message(priority, pgn, sa, timestamp, data):
    """Receive incoming messages from the bus

    :param int priority:
        Priority of the message
    :param int pgn:
        Parameter Group Number of the message
    :param int sa:
        Source Address of the message
    :param int timestamp:
        Timestamp of the message
    :param bytearray data:
        Data of the PDU
    """
    print("PGN {} length {}".format(pgn, len(data)))

def main():
    print("Initializing")

    # create the ElectronicControlUnit (one ECU can hold multiple ControllerApplications)
    ecu = j1939.ElectronicControlUnit()

    # Connect to the CAN bus
    # Arguments are passed to python-can's can.interface.Bus() constructor
    # (see https://python-can.readthedocs.io/en/stable/bus.html).
    ecu.connect(bustype='socketcan', channel='can0')
    # ecu.connect(bustype='kvaser', channel=0, bitrate=250000)
    # ecu.connect(bustype='pcan', channel='PCAN_USBBUS1', bitrate=250000)
    # ecu.connect(bustype='ixxat', channel=0, bitrate=250000)
    # ecu.connect(bustype='vector', app_name='CANalyzer', channel=0, bitrate=250000)
    # ecu.connect(bustype='nican', channel='CAN0', bitrate=250000)

    # subscribe to all (global) messages on the bus
    ecu.subscribe(on_message)

    time.sleep(120)

    print("Deinitializing")
    ecu.disconnect()

if __name__ == '__main__':
    main()
