Nolan_Garrett:

minimum emonSD storage size will be 8GB, up from the 4GB minimum.

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

Nolan_Garrett:

Looks like I can confirm this boots! I’ll mess with it later today and ensure the whole image is working, but the boot was successful, so I think we’ve found the root cause of that problem. Thank you, @glyn.hudson for your work on this! I’ll post back if I find any other problems as I am setting it up.

Exangel:

It seems to work also on my side. It’s booting right now.

It should be fine then.

Thanks.

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: emonSD pre built SD card Download & Change Log · openenergymonitor/emonpi Wiki · GitHub

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

I can also confirm that the new image works fine as well on my SanDisk cards, thanks @glyn.hudson

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
Loaded: loaded (/etc/init.d/mysql)

And this is how much:
df -hlx tmpfs
Filesystem Size Used Avail Use% Mounted on
/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!

garzak · 2017-12-07T18:57:39.287Z

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!

pb66 · 2017-12-07T19:03:29.991Z

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

Thanks!
Dont know why, but that line was with # (comented!)
