when I ran this command this morning, I got the same result as last week, but now it seems to be updated

@TrystanLea - these errors anything to worry about?

Hi @VincentR (@TrystanLea)

I’ve had a chance to look at the logrotate errors. Part of the issue is a change to logrotate making 2 of the commands we were using mutually exclusive (reference make `renamecopy` and `copytruncate` override each other by kdudka · Pull Request #386 · logrotate/logrotate · GitHub & logrotate/ChangeLog.md at master · logrotate/logrotate · GitHub)

Firstly have you seen any other problems with log size (I’m expecting you will)

I have modified the logrotate files. If you want to give them a try, I can walk you through the process.

Changes to logrotate package are causing issues

References * https://github.com/logrotate/logrotate/pull/386 * https://githu…b.com/logrotate/logrotate/blob/master/ChangeLog.md#3181---2021-05-21) * https://community.openenergymonitor.org/t/no-disk-space-although-enough-room/22042 1. Key issue is that 'copytruncate' and 'renamecopy' are now mutually exclusive. 2. There is also an issue caused by removing the `emonhub` user/group 3. There seems to be an issue with the `renamecopy` line in the `00_olddir` config file. deleting the line and restoring it solved the issue. This should be tested with `sudo /usr/sbin/logrotate -d /etc/logrotate.conf` - pay attention to errors in first few lines as config files are read.

Hi Brian,

thnx for the determination of this problem, as I’m overasked by this.

As of Christmas I did not take a look at the filesizes anymore (will do when I’m home), but still experienced the troubles with the “inputs” menu.

I’m really interested in the modified files, but not very common to the RPi commandline interface. Never to young to learn, so please guide me through.

Hi Brian, reading your discussion with Alexander on Github I was wondering what to do for me? Can you guide me through the necessary steps?
