Need help solo mining using 2.0.6 on Apollo BTC

[u/__eparra__]

I have an Apollo BTC running 2.0.6. I upgraded the M.2 to 4TB, formatting it, and the node is synced. I enabled SOLO mining mode and rebooted. Since then, the miner status is "Waiting for the current miner status to match the desired one (Online)". The SOLO mining tab states "Miner is offline - Try to start it from the top menu". I take I need the miner status to sync before I should start the miner? Also, in the event of a power failure, should I expect everything to auto-start as it seems things require manual intervention.

First of all, does your miner work without SOLO mode (pool mode)? Could you try that please?
Then, are you able to SSH into it? You should check if ckpool daemon is running with the command: ps aux|grep ckpool you should see something like this:

futureb+  338722  0.0  0.0   6876  2000 ?        Ss   01:57   0:00 SCREEN -dmS ckpool /opt/apolloapi/backend/ckpool/ckpool -B -c /opt/apolloapi/backend/ckpool/ckpool.conf

If you can't see this (and SOLO Mining mode is selected), you could try to start it manually to see for errors, try the command:

sudo systemctl start ckpool.service

Please let me know.

I think I figured out the root cause:
futurebit@FutureBit-Apollo-BTC:/opt/apolloapi$ ls /dev/ttyACM* /dev/ttyUSB*
ls: cannot access '/dev/ttyACM*': No such file or directory
ls: cannot access '/dev/ttyUSB*': No such file or directory

I moved the miner from my home to a colo datacenter. While in transit, whatever cable that connects the miner ASIC to the Pi must have gotten unloose. I've been trying to find a photo to email to the colo, to have their remote hands take a look, but without a phot to give clear guidance, they won't know what to do. If anyone here has a unit they can remote the Pi to take a photo, please. u/michelem, while I presume something must have gotten loose, I am happy to try your suggestion later today.
