Help request- Adding increased hard disk space to Ubuntu server vm

[thelonghop]

I'm using Proxmox 7.2-7, and have a Ubuntu server vm. I tried to upgrade the server but got a not enough space warning, so I increased the hard disk size in the hardware tab and it now has 48GB. However, I still get the not enough space warning, so I'm not sure how to attach the extra storage.

Isn't that easy. You just increased the size of the virtual disk, so you now got 12GB of partitioned space and 36GB of unallocated space. You now would have to:
1.) increase the size of your sda3 partition with the partitioning tool of your choice
2.) extend the size of the PV, VG and LV (for example lvextend command)
3.) extend your filesystem of the ubuntu LV (for example resize2fs command)

This is not really a Proxmox problem. All PVE can do is increasing the size of the virtual disk. All other things have to be done from inside the guest. This is not different like with a bare metal Ubuntu install, so there should be lots of tutorials out there.
