Expanding Linux VM Partitions within ProxMox

EndeavourOS/Arch Linux

Shut down the VM and within Proxmox go to Hardware > Hard Disk > Resize
- Expand the Main disk, and secondary disk (linuxswap) as needed
Boot up the VM again, log into a user account and open up KDE Parition Manager paru -S partitionmanager
If Expanded the main disk, select it, right click on the main partition and click resize and then expand it to use up all the new disk space alloted to it.
- Sometimes the extra disk space doens’t appear, a reboot of the VM usually fixes this.
If expanding the linux swap partition, you will need to delete the old partition and recreate it as a new linuxswap partition
- right click on the partition, “deactivate swap”
- Right click and click “delete partition”
- Apply the changes
- Right click on the empty partition and create new primary partition of the type linuxswap
- Apply the changes
- Right click on the newly created partition and select activate swap
- Right click on the newly created partition and view it’s properties.
- Copy the UUID to your clipboard. NOT the partition UUID.
- open up your fstab file with sudo nano /etc/fstab and copy the new linux partition UUID and overwrite the old swap partition ID.
- reboot the VM to make sure that the swap partition gets auto mounted.
- easy way to check is open up htop in the terminal and see if the swap has a disk size to it.

Run the following commands on the expanded drive:
