Hey everyone,
I believe growpart works for EXT4 only and does not work on Centos
because it is XFS so volume needs to be resized manually. Here is what I use to
do configure the template scripts:
## Enable XFS root partition auto resize
echo "growpart:
mode: auto
devices:
- \"/dev/xvda2\"
ignore_growroot_disabled: false" > /etc/cloud/cloud.cfg.d/50_growpartion.cfg
echo "runcmd:
- [ pvresize, /dev/xvda2 ]
- [ lvresize, -l, '+100%FREE', /dev/centos/root ]
- [ xfs_growfs, /dev/centos/root ]" >
/etc/cloud/cloud.cfg.d/51_extend_volume.cfg
Full script you can find here ->
https://github.com/dredknight/cloud_scripts/blob/master/CloudStack-Xen/templates/centos7_clean.bash
I also made an extended article regarding cloud-init features and their
step-by-step config for CLoudstack but that is committed for 4.16 documentation
but I am not sure if it is approved for merge or not.

Best regards,
Jordan

I believe there's a section called boothook in cloud-init which is probably
what you want.
We're also trying things on cloud-init. ☺️
