Hi all, I am setting up a golden image to be used with mender-convert. I’m a little confused by these different options: MENDER\_STORAGE\_TOTAL\_SIZE\_MB MENDER\_BOOT\_PART\_SIZE\_MB MENDER\_DATA\_PART\_SIZE\_MB I installed a few packages on Raspian Bullseye 32bit but they definitely took 3-5gb of space. My SD card is 32GB. I used the “dd” command which resulted in a ~32GB image. How should I set the above settings? I’d like 3-4GB extra incase we decide to install more packages down the line. Otherwise I’ll want an ample amount of persistent data. Thanks in advance. ---

Hi @bp1313, Wow, 3-5GB of actual payload on a Raspbian? That definitely feels bloated. As a rule of thumb, I would suggest something like this: - boot partition: 128-256MB - root partitions: 2x current size - data partition: remaining. If the root filesystem takes up 4GB by now, then I would for example make partitions A and B 8GB each. Note: this is a personal opinion, your use case and requirements may differ. Greetz, Josef
