Hi, I have RPI based project based originally on thud poky release and I’m in process of bumping existing project to dunfell branch. All went smooth but I have an issue with creating sdimage where wic creation failed with messages that actual rootfs size is higher then computed: ```auto ERROR: File system image of partition None is larger (425984 kB) than its allowed size 409600 kB ``` Thing is I cannot increase `MENDER_STORAGE_TOTAL_SIZE_MB` because then I cannot perform mender update from thud to dunfell. I tried to adjust various variables but without success. Does anybody resolve such problem? Ideas? Thanks. ---

I had a similar issue going from Sumo to Dunfell. But in my case I was able to fix it by adjusting MENDER\_STORAGE\_TOTAL\_SIZE\_MB. @kacf any ideas? ---

My problem is that I want to be able to switch back from dunfell to thud releases. So for thud rootfs size was 413M. I played with `MENDER_STORAGE_TOTAL_SIZE_MB` but cannot make image with rotofs which fits to 413MB.I think it’s due to the fact of automatic rootfs size computation was changed or so. Thanks. ---

You mean you can’t get it to fit exactly, or you can’t get it to decrease at all? Does it work to set `IMAGE_ROOTFS_SIZE` to the desired value? ---

Hi, I would like to have dunfell release have same rootfs size. I tried also to set `IMAGE_ROOTFS_SIZE` to exact rootfs size but it IIRC I get an issue with size mismatch. ---

I can’t reproduce this, can you post the output? ---
