Re: [WIC] Grow last partition up to disk size

Michael Nazzareno Trimarchi


Well I have write something like this

Description=Increases rootfs image size to fit partition

ExecStart=/usr/sbin/sgdisk /dev/disk/by-path/platform-ff0f0000.dwmmc -e
ExecStart=/usr/sbin/parted /dev/disk/by-path/platform-ff0f0000.dwmmc
-s "resizepart 4 -1" quit
ExecStart=/sbin/resize2fs /dev/disk/by-partlabel/rootfs
ExecStart=/bin/systemctl disable resize-rootfs.service

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
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)







as simple and primitive as possible
