Image size is too large

[jmztaylor]

I have a fresh intall of Proxmox using the ISO Installer. I have a 5TB partition for /var/lib/vz. I am trying to create a 3TB KVM image. When doing it through the web interface I get an error. And this applies to all sizes. I tried to even create a 10GB one and it still fails with the same error.

I have checked free space and on /var/lib/vz it shows 4.5TB free.

Any advice would be appreciated

Try to reboot your Proxmox node then create a disk image of smaller size like 100GB to see if it works.

Did you do any manual configuration to the image file?

Also, instead of creating a giant single disk image file, try to create multiple smaller ones then use LVM to use to multiple disk images. In your case 3 1TB disk image or 6 500GB would work better.

I'm not sure, but I think that qcow2 files have around 2TB limit.
