Issue with disk space in Proxmox VM.

[mustaq.merchant]

Hello,

We have created a Templates of 40GB storage in our ProxMox Server and using the same we have created a VM which has 40GB storage, later we have resize the VM to 80GB storage from Proxmox where it shows 80GB but on VM it shows 40GB storage and 40GB storage as unassigned.

We have cPanel installed on this and it shows 40 GB. Request you to guide me on this issue.

Hi,
this is normal - pve simply extend your harddisk and don't touch the partitiontable (and this is very very good).

So it's by you to decide who you use the addition space.

If you wan't to extend your VG you can use 2 ways:
1. the safe way: create another partion and extend your VG by this partition
2. the smart way: remove your partion2 and create an new on with the same start (important!!) and the whole size - reboot - and vgextend
