Proxmox install boot options

linux ext4 hdsize=8

linux ext4 hdsize=10

linux ext4 hdsize=12
linux ext4 hdsize=16

For Proxmox 5.x I have been using linux ext4 hdsize=16 for 16GB in my PVE Root capacity. After Proxmox has been completely installed I usually have 1.4GB Free.

• linux ext4 – sets the partition format to ext4. The default is ext3.
• hdsize=nGB – this sets the total amount of hard disk to use for the Proxmox installation. This should be smaller than your disk size.
• maxroot=nGB – sets the maximum size to use for the root partition. This is the max size so if the disk is too small, the partition may be smaller than this.
• swapsize=nGB – sets the swap partition size in gigabytes.
• maxvz-nGB – sets the maximum size in gigabytes that the data partition will be. Again, this is similar to maxroot and the final partition size may be smaller.
• minfree=nGB – sets the amount of free space to remain on the disk after the Proxmox installation.
