I have no idea what a USB drive has to do with anything you're mentioning.

10:54:27 your clock synched so after that we should be able to trust the 
timestamps in the syslog

11:17:25 weewx start
11:18:24 weewx stop

11:18:35 weewx start
(no visible weewx stop)

11:27:40 weewx start
(no visible weewx stop)

11:41:01 looks like you rebooted
11:41:37 system coming back up after reboot

11:41:48 weewx start

I'd suggest a couple things

   - if you have to do things with USB, you likely don't have enough power 
   being supplied to the pi.  See if you have a stronger power supply to use.
   - set debug=1 in weewx.conf so it logs more verbosely, at least until 
   things stabilize
   - you're not showing us any weewx activity re: archiving, running skins, 
   etc.  Check if it's going to a different file in /var/log on your pi.

Re: [weewx-user] running weewx directly and as daemon

[brisguy foo]

My original complaint was that I could not get the daemon to START without 
rebooting the system. I never mentioned problems with shutting it down. If 
you look at the log starting around 10:47, you'll see messages indicating 
that weewx has started, but it should have posted a new record at 11:50 
(and every five minutes thereafter), but did not. Same thing starting at 
11:27. At that point, I reboot so I can mount a USB drive onto the system, 
which involves disconnecting the weather-station since I only have one USB 
port I can use! After that reboot, the system ran normally.

Anyway, if I am using the correct commands, I'm fine. I may try running 
more tests using the 'systemctl' on the command line when starting the 
daemon.

I guess I'm missing what you see in the log that leads you to think it 
didn't shut down.

Try a test.do a 'sudo systemctl stop weewx' and see what it 
saysthen do 'sudo systemctl status weewx'then do "ps aux | grep 
weewx" and see if there are any processes actually running

Re: [weewx-user] running weewx directly and as daemon

[Tom Keffer]

It's hard for me to unravel what's happening. The only thing i can suggest
is to use systemctl. Seems to work for me:

sudo systemctl start weewx

Sorry, but I don't have any insights.

Re: [weewx-user] running weewx directly and as daemon

[Tom Keffer]

Depends on the operating system, but you have the general idea.

You may not think there is anything useful in the log, but please humor me:
post it anyway. And, tell us the operating system.

[weewx-user] running weewx directly and as daemon

[brisguy foo]

I had to do some debugging og my weewx installation recently and needed to 
swap back and forth between running directly and as a daemon. However, once 
I used the direct method, I never seem to be able to get the daemon 
launched again without just doing a reboot.

I have been doing the following (starting from a running daemon)
sudo /etc/init.d/weewx stop  # to stop the daemon
sudo weewxd /etc/weewx/weewx.conf  # to run directly
CTL-C   # to stop running directly
sudo /etc/init.d/weewx start  # to start the daemon

After the attempt to start the daemon, the terminal responds [OK], but 
looking at the syslog file, I can see it never did and there is no error 
message. At this point, I reboot and things run fine.

What is the correct way to start/stop these processes?
