Proxmox could not be installed on large Volume

I am having some trouble installing the latest build of proxmox. I am trying to install it on a PE2950 with a large virtual disk (10tb). I have tried setting paramaters (linux ext4 maxroot=25 swapsize=8 maxvz=400 minfree=32) at the boot prompt to install in by setting the sizes of the volumes but I keep coming across the error -

command 'chroot /target dpkg --force-confold --configure -a' failed with exit code 1 at /usr/bin/proxinstall line 172

Does anyone have any advice please?
