GUI: Farming status is green "Farming" but plots are unmounted

v1.0.0

I was checking status of farming via GUI (x11vnc headless) once a day on my storage “server” and everything was OK

I went to add new plotted plots to my farm and find out that exernal drive has been unmounted 3 days ago due to error, dmesg:

I think it was caused physically by me (pushed with hand into USB connector when I was removing another USB drive). But after that I checked via GUI whether everything is OK, but was not 😃

so I checked CLI and found out

$ chia plots check

But in GUI:

After I mounted drive again it’s working:

17:59:34.965  src.plotting.check_plots         : INFO     Summary
17:59:34.965  src.plotting.check_plots         : INFO     Found 3 valid plots, total size 0.50695 TiB

17:59:34.966  src.plotting.check_plots         : INFO     2 plots of size 33

But how can I check that I’m really farming? I’m really not sure. Thank you in advance.

Yeah, I have the same problem. GUI says “farming” but “Last Attempted Proof” is hours ago. Normally it should update every few seconds. I discovered that restarting the process “start_farmer.exe” starts farming again. But a few minutes/hours later the same problem happens. It’s pretty annoying. Because of this issue I “farmed” 3 days without getting rewards. I’m on Windows 10.

My farmer paused again at 17:51. Debug Log says the following:

Every time this happens, restarting the service “start_farmer” helps. But unfortunately there is no notification when “Latest proof attempts” get stucked.
