... low level copy via dd on the base devices. When new card is larger you can use fdisk on base device to enlarge data partition and later use resize2fs to enlarge data file system. I will need you to have aLinux system at hand that can access the SD cards. You will need some deeper device ...

when you search in the forum you will find a lot of descriptions how to port to a larger storage card.

search.php?keywords=resize2fs

you can shut down the system, do a low level copy (dd or similar) to a larger storage medium, start meteohub with that medium.
then you can do in place enlargement of data partition as described by a couple of users in this forum. search for "resize2fs".

hi, there is a detailed report somewhere in this forum how to enlarge the data partition on a running meteohub system.
When you search a bit you should find it.

... 17) Now we are ready to resize, by default linux will use the entire parttion, which will make our command very straightforward:
meteohub:~# resize2fs /dev/hda3

Resizing the filesystem on /dev/hda3 to 1803296 (4k) blocks.
The filesystem on /dev/hda3 is now ...

4GB will last for 5 years or more.
You can use larger cards. Put the 4GB image on that and growth 3rd partition via fdisk (I don't recommend this to a novice, as you can easily delete your CF card by this) and grow ext3 file system on 3rd partition with "resize2fs" after that.

... login on Meteohub via ssh, use fdisk "fdisk /dev/mmcblk0" and delete 3rd partition, create a new 3rd partition that start directly after 2nd and uses all space up to the end, write changes and leave fdisk. Next make use of "resize2fs /dev/mmcblk0p3" to expand the filesystem to the changed partition.

I think I am starting over with a fixed filesystem (resize2fs /dev/loop0) - I am unsure about online resizing on the slug with the usb stick, maybe I am trying this later today, when I am near the slug ...

... data partition might work. You can do that from any linux system where you mount the stick. Just change size of partition 3 to max, and make a resize2fs on it. voila...

At the moment this cannot be done from Meteohub itself as the platform is missing the necessary ext3 tools. They might be ...
