Ok I’ve been able to fix it myself after bashing head against the wall

chown -Rv observium:www-data rrd && chmod -R g+w rrd

It would be nice if the was a migrate guide on the docs.observium.org http://docs.observium.org/ as the is only a migrate guide for between 32bit to 64bit NOT server to server

Hi All

Im trying to find out if I have done something wrong or maybe missed something?

I have done a migrate from ubuntu 16.04 to ubuntu 18.04 and now ALL of my RRDs have stopped being written?

1. mysqldump to backup, scp file to new server, then mysql to restore
2. Scp the whole rrd folder from old server to new server
3. Scp the old config.php to new server

Only thing I have done differently is use the setup script instead of manually installing observium

On the new server the rrd folder shows

drwxrwsr-x 60 observium www-data 4.0K Apr 24 16:29 rrd

But the old server shows it as

drwxr-xr-x 60 www-data www-data 12K Apr 24 15:57 rrd

One of the folders inside rrd show this

drwxr-xr-x 2 root www-data 4096 Apr 24 15:58 localhost

And an rrd file shows this

-rw-r--r-- 1 root www-data 115K Apr 24 15:58 perf-poller.rrd

Did I overwrite the folder permissions by accident?
