error creating new system on separate disk

Hi every body,

this is my first trial using cloud min

i'm using two disk configuration for the cloudmin master. the first disk , a 80GB Disk,is configure to used with the linux master system. the second disk, 1TB, is where the created cloudmin host would be.

on the cloudmin's xen host setting, i have set base directory for virtual system to the second disk mount point. but when i create new system, cloudmin always fails with error not enough diskspace. a few hudreds gigs short.

can someone help me?
