Full_node and wallet failed to start after upgrade to 1.2.11 (b74a3f3)

Env: Ubuntu 20.04 , running on git working copy.

Today I upgrade my chia box from 1.1.7 (b075e5bb8) to 1.2.11 (b74a3f3).
But failed to start full_node and wallet after upgrading.

(venv) xiaogang@xiaogang-chia1:~/chia-blockchain$ chia start node
chia_full_node: started
(venv) xiaogang@xiaogang-chia1:~/chia-blockchain$ ps axu | grep chia

It is weird that no log output in $HOME/.chia/mainnet/log/debug.log
I guess something unexpected happened before ‘logger’ got inited.

Then I found that, if I start chia daemon in systemd service (the way I used to start chia),
I can see some system journal related to this issue.
My systemd service warpper likes:

. ~/chia-blockchain/activate
chia start farmer

and in 【journalctl -u chia.service】, I got:

I have no idea about ‘main.sym’, I ‘find’ it in ‘venv’ dir, but found no one.

Now I stucked :frowning:
Any hint will help, thanks in advance.

I would reboot to get rid of the Zombie process and then go with
. ./activate
chia start farmer
In the chia blockchain folder.

If that doesn’t work then try installing again

I figured out the cause.
‘main.sym’ will be created while ‘chia init’ creates $HOME/.chia/mainnet.

If I upgrade chia, $HOME/.chia/mainnet remains, and ‘chia init’ saids that ‘no need to create mainnet …’
so I didn’t get ‘main.sym’.

I just moved $HOME/.chia/mainnet away, and ‘chia init’ again, and then everything became normal. :slight_smile:

And this is why you have flexfarmer in reserve so you can start it up like a spare tire and keep farming while you diagnose your node problems :smiley:
