Hi @ravipathak, normally this just means that you need to increase MENDER\_STORAGE\_TOTAL\_SIZE\_MB. Drew ---

Given the size involved, I would suspect that this is due to `MENDER_BOOT_PART_SIZE_MB`, not `MENDER_STORAGE_TOTAL_SIZE_MB` (which only affects the rootfs). Try to raise `MENDER_BOOT_PART_SIZE_MB` to 32 instead. ---

@kacf that worked for me. Thanks!
