VM disk Size

[TheDarthFather]

Hello,
I do have a small issue.
I created a VM with 500GB a few months ago. Lately I've seen I have only ~20% free ... when I realised that somehow my "main" partition is only 200GB.
I am a little lost on what do I need to do and why is like this.
Why maper has only 200GB and how can I make it use the full 499 GB ?

The second VM is even more strange ... the total is 100GB but sda3 is only 31GB. I assume this one was resized.

Thank you!

GPT PMBR size mismatch (67108863 != 209715199) will be corrected by write.
The backup GPT table is not on the end of the device. This problem will be corrected by write.

Thats how the Ubuntu installer works. If you just click "ok" everythere and keep the default values the ubuntu installer won't use the complete space. So you need to manually resize your VG, than resize the LV and then grow your filesystem.

Thank you for your quick answer!
How can I do this 'safely' ?

There are alot of tutorials out there how to resize a LVM. Best would be you google for a ubuntu tutorial because that has nothing to do with your PVE host.
