Bug#784673: cloud-utils: growpart fails with gpt
Package: cloud-utils
Version: 0.27-1
Severity: normal
User: debian-powerpc@lists.debian.org
Usertags: ppc64el
Dear Maintainer,
I did a ppc64el installation with the latest Jessie ; then on a 100G disk, put
the prep partition, the swap and a third partition for / leaving ~90G of free
space after.
Then after booting, I did this :
---
root@vm6:/tmp# growpart -v /dev/sda 3
max_end=0 tot=209712510 pt_end=0 pt_start=0 pt_size=0
NOCHANGE: partition 3 is size 0. it cannot be grown
---
The error seems related to the fact that the output of sfdisk is unusable :
growpart tries to parse : sfdisk -d /dev/sda which gives :
---
root@vm6:/tmp# sfdisk -C 13054 -H 255 -S 63 -uS -d /dev/sda
# partition table of /dev/sda
unit: sectors
/dev/sda1 : start= 1, size=209715199, Id=ee
/dev/sda2 : start= 0, size= 0, Id= 0
/dev/sda3 : start= 0, size= 0, Id= 0
/dev/sda4 : start= 0, size= 0, Id= 0

I did some checks with the latest util-linux 2.26.2 and it seems sfdisk has now
better support for gpt :
---

Then I adapted growpart (as sfdisk had some options changed) and ran it :
---
root@vm6:/tmp/util-linux-2.26.2/.libs# growpart -v /dev/sda 3
max_end=209712510 tot=209712510 pt_end=13688832 pt_start=7829504 pt_size=5859328

I looked for those needed changes and :
- NEW/experimental: 2.26.2-2 : https://tracker.debian.org/pkg/util-linux
- https://code.launchpad.net/~smoser/cloud-utils/growpart-sfdisk-2.26
: "initial start at sfdisk 2.26 support"
Everything seems on its way.
So, that'd be nice, when possible to update util-linux to 2.26.2 and have
cloud-utils with growpart and support for sfdisk 2.26.
Thanks,
Fred
