SDcard full of log files - (TCP error TP-Link)

General
1

Today my 16GB sdcard totally filled up and crashed node red. Luckily I had my flows backup up from a few days back.

The culprits are:

var/log/daemon.log (3.5GB)
var/log/syslog (0.5GB)
various .gz log file totalling 3GB

I copied the logs to my computer and deleted them from the sdcard, now it's running fine.

The log files are full of this over and over (I could not even post 1 seconds worth it's too long!!!)
It seems to be the TP-Link node - I think.

Any ideas?

This is actually a TP-Link lightbulb I recently added to my system, and is unplugged - hence unreachable. Surely node red should not be logging this this extent?

We’ll Node-RED will log what it is told to. So I would open an issue against that tplink node and ask the author to stop it retrying so often

Yes absolutely! I will raise an issue on github.

I know this is more of a Raspberry Pi question but is there anyway to limit the log file sizes in future?

5

Yes. Read up on the logrotate function and its settings.
