The perfect setup Debian 9 VM image - increase VM storage on ESXi 6.7?

Hello,

I downloaded VM image from this tutorial https://www.howtoforge.com/tutorial...-9-stretch-apache-bind-dovecot-ispconfig-3-1/ and updated everything to the latest version.
I realized again that VM image was created on 30GB virtual disk and I thought that I had well documented how-to process from my same issue but on Ubuntu https://www.howtoforge.com/communit...ase-vm-storage-on-esxi-6-5.78214/#post-370182
It turns out there are some changes and it does not work on Debian 9.
Once booted in Gparted live http://prntscr.com/kd7vx8 it did not show lvm partition like it did in Ubuntu https://prnt.sc/i3sahz and df -h was showing /dev/sda1 as /

Code:

root@debian9:~# df -h
Filesystem      Size  Used Avail Use% Mounted on
udev            990M     0  990M   0% /dev
tmpfs           200M  5.8M  195M   3% /run
/dev/sda1        28G  3.3G   23G  13% /
tmpfs          1000M     0 1000M   0% /dev/shm
tmpfs           5.0M  4.0K  5.0M   1% /run/lock
tmpfs          1000M     0 1000M   0% /sys/fs/cgroup
tmpfs           200M     0  200M   0% /run/user/0
root@debian9:~#

I had to install lvm2

Code:

root@debian9:~# lvextend -l +100%FREE /dev/sda1
-bash: lvextend: command not found
root@debian9:~# apt-get install lvm2

After installing it I was getting this error:

Code:

root@debian9:~# lvextend -l +100%FREE /dev/sda1
  "/dev/sda1": Invalid path for Logical Volume.
  Run `lvextend --help' for more information.

What am I doing wrong?

TIA

 

Ok, so I was able to expend boot portion using only Gparted. Did I miss anything?

Below are screenshots outlining steps I've taken in case someone runs into same issue.

Thanks for the reply! Yes, it does show correct size and that is good enough enough for me.

Maybe sometime down the road it would be benefit to have tutorial on how to resize it because all VM images here have the same size and I cannot imagine 30GB on a server is enough. Just an idea!
