Hi stackers,
I have come across this problem of growpart/resizefs not working with
CentOS 6.5 Cloud image on first boot.
Here is the relevant config in cloud.cfg
==============================
growpart:
mode: auto
devices: ["/"]
resize_rootfs: True
resize_rootfs_tmp: /dev
cloud_init_modules:
- bootcmd
- write-files
- growpart
- resizefs
Here is the relevant log on first boot:
============================
[CLOUDINIT] helpers.py[DEBUG]: Running config-growpart using lock
(<cloudinit.helpers.DummyLock object at 0x1ed06d0>)

[CLOUDINIT] util.py[DEBUG]: Running command ('resize2fs', '/dev/vda1') with

[CLOUDINIT] util.py[DEBUG]: Resizing took 0.004 seconds
In the base image, I have upgraded cloud-init to 0.7.4-1.el6, and installed
cloud-utils, cloud-initramfs-tools. After the first *reboot*,
growpart/resizefs does their job and the root file system is grown to disk
size.
After a reboot, the relevant cloud-init logs:
===================================
cc_growpart.py[DEBUG]: '/' NOCHANGE: no change necessary (/dev/vda, 1)
util.py[DEBUG]: Resizing took 13.776 seconds
cc_resizefs.py[DEBUG]: Resized root filesystem (type=ext4, val=True)
I wish the growpart/resizefs happen on first boot, what can I do?
