[WIC] Grow last partition up to disk size

[WIC] Grow last partition up to disk size

[Rudolf J Streif]

[-- Attachment #1.1: Type: text/plain, Size: 345 bytes --]

I was looking for a way in a wks file to have wic grow the last
partition to fill up the remainder of the disk. Of course wic does not
know how large the disk is but that could be a parameter.

The alternative way is to use fixed-size and do the math manually but
that would not allow wic to grow a partition based on content.

You can use https://manpages.debian.org/testing/systemd/systemd-growfs.8.en.html
which grow partition to the end.

can it grow a mounted partition ? since that will be the case when 
growing rootfs partition.

It will grow last partition in first boot only.

my question was will it grow a mounted rootfs parition if that happens 
tobe the last partition, I understand it will grow last partion and do 
it as firstboot service.

I usually use it in case when have dual rootfs (A, B) and data
partition which is expanded to then end of disk.
I don't have experience with growing rootfs (I think it can grow only
not mounted partitions)

Thanks, guys, I appreciate it.

Doing it dynamically on first boot would probably work as it is a data
partition and not the rootfs partition.

I will give it a try.

96boards-tools also has a script which works regardless of init systems

If you use btrfs you can even resize the rootfs (mounted) partition.

Yes, a mounted ext4 partition can be resized. Some tools will try to 
keep you from doing that though, had to patch parted to stop whining 
about mounted partitions in "scripted" mode that to make it work though.

https://github.com/topic-embedded-products/topic-platform/tree/zeus/meta-topic-platform/recipes-extended/parted

Here's the recipe that re-partitions the SD or eMMC on first boot after 
programming a (small) wic image:
