Optional ability to log weather data to separate USB stick

Please add the feature to optionally log the weather data to a separate USB stick from the boot stick.

Thus sparing the boot drive from an early death.

Very interesting idea. I think that this won't be a big problem, because you can automount the usb-stick to /data. I just ordered a XPorter XT and give this a try with my Alix3d3. When everything works well, I'll post my results here.

Easy going:

1) Insert USB - Stick
2) check the disk-name (tail -f /var/log/messages), in most cases it will be /dev/sda
3) remove the FAT32 Partition (fdisk /dev/sda ( in case the stick is sda, otherwise you have to change the parameter, or data will be lost! -> delete partition (d), create partition (n)
4) format USB-Stick: mkfs.ext3 /dev/sda1 (in case the stick is sda)
5) create (temporary) mount point: mkdir /mnt/sda1
6) mount usb-stick: mount /dev/sda1 /mnt/sda1
7) stop meteohub via the webinterface
8) copy all files from /data to the stick: cp -a /data/* /mnt/sda1
9) edit /etc/fstab (Attention: be careful, in case of mistakes the system won't boot anymore)):
copy the line which mounts /data (/dev/hda3 /data ext3 noatime 0 2) into a new line.
In the new line change /dev/hda3 to /dev/sda1
Escape the original line with a # - so fstab has to look like this

Code: Select all

#/dev/hda3      /data           ext3    noatime         0       2
/dev/sda1       /data           ext3    noatime         0       2
Reboot and your'e done. 5 Minutes in total, works fine :)
