Error: EIO: i/o error, read (line:44)

Hello, I want to ask a problem without doing anything. Recognized by the information not sent to the database.

  1. At the node setting "Error: EIO: i/o error, read (line:44)"
  2. I tried to reboot but it show "-sh: Reboot: command not found" so I googled it and found "which reboot , /sbin/reboot".
    -> The problem is that "node-red" doesn't auto-start itself. I ticked the right place "iot2000setup -> sw -> manage autostart" already.

How can I solve this problem ?
thank you very much
