Correct. It has been realistically 8GB for the Nov16 release also once the image is expanded to a usable size.

Excellent. I will make the this ‘slim’ image the new emonSD-26Oct17 image download. The download link above will stop working. Please use the normal emonSD-26Oct17 download link: https://github.com/openenergymonitor/emonpi/wiki/emonSD-pre-built-SD-card-Download-&-Change-Log

OK! Thanks.
Now it works. I was able to install on a 64GB ScanDisk microSD card.

Well… I have now another problem:

  • when i do the “emonSDexpand” the raspberry reboots and then stays very slow and nothing works! I cant enter emoncms etc…
  • after the comand (sudo emonSDexpand) i get a warning: “Re-reading the partition table failed”

Does anyone gets the same?

When I try to enter emoncms I get:
“Can’t connect to database, please verify credentials/configuration in settings.php
Error message: **Can’t connect to local MySQL server through socket ‘/var/run/mysqld/mysqld.sock’ (2)”

After running the comand "sudo systemctl status mysql.service -l"
I get:
● mysql.service - LSB: Start and stop the mysql database server daemon

And this is how much:
df -hlx tmpfs

/dev/root 3.4G 2.0G 1.2G 63% /
devtmpfs 481M 0 481M 0% /dev
/dev/mmcblk0p1 60M 22M 39M 37% /boot
/dev/mmcblk0p3 11G 39M 11G 1% /home/pi/data

The microSD is of 16GB and the image is brand new!

Just realised now, that I have to mount:
sudo mount /dev/mmcblk0p3 /home/pi/data
and then start the mysql service again to solve the problem each time the raspberry pi reboots!
Crazy!

Not if it is defined in /etc/fstab, then it will mount at boot.

you should have a line there something like

/dev/mmcblk0p3 /home/pi/data ext2 defaults,rw,noatime,nodiratime,errors=remount-ro 0 2
