[RAUC] Partition resize

[RAUC] Partition resize

[Kilimci, Caglar]

Hi all,

I have a question or a missing point. After the successful update, my partition size is reduced. If I extend it, it would be as expected. Like this:

Before update:
root@phyboard-regor-am335x-1:~# df -h
Filesystem                Size      Used Available Use% Mounted on
/dev/root               375.8M    207.7M    144.6M  59% /
devtmpfs                240.9M         0    240.9M   0% /dev
..

After update:
root@phyboard-regor-am335x-1:~# df -h
Filesystem                Size      Used Available Use% Mounted on
/dev/root               305.8M    207.7M     77.9M  73% /
..

Is there any automatic way to extend partition or am I doing something wrong?

Thank you for your help.

Regards,
Caglar

I'm guessing your root-FS type is ext4? In that case, you are probably
installing a filesystem image with was produced with a fixed size less
than the device size. RAUC doesn't modify the image during
installation.

The easiest way for you is probably to use a .tar.gz archive instead of
the filesystem image. Then RAUC will format the partiton using
mkfs.ext4 and extract the tar into the new filesystem. In that case no
resize is needed.

Alternatively, it could be useful to optionally let RAUC call resize2fs
on installation of a ext4 image.

Regards,
Jan

That is the perfect way. Yes, I used ext4 type and I have tried tar archive and it works. Only thing remains is updating bitbake file for it.

Yes, I have learnt this but I do not want to do after installation.

Thank you for your help.

Sincerely,
