Not all disk space available after installation

[audunms]

Hello, and sorry for what is probably a very newbie question.

I installed Proxmox 2.1 on a single server, whith 2 SATA hard drives installed.

After installing, I added the second hard drive with "pvcreate /dev/sdb", "vgcreate satadisk2 /dev/sdb" and added a LVM Group in the web interface where I selected the "satadisk2" as Volume Group. This second hard drive displays all the space on the physical disc as available:


However, the first disk (local), which was selected under installation, displays only half of the disk's around 170GB as available:


In case this is of any help, here is the output when running fdisk -l via ssh:

Greatly appreciate any help.

the gui shows just the size of your root partition.

to check and understand your disk layout, see the following commands:

df -h

lvs

pvs

Thank you for your answer.

From what "df -h" gives me, is it correct to assume that ~88GB is available for ISO's and Virtual Machines (/dev/mapper/pve-data?), and the rest is used for temp files + host usage (/dev/mapper/pve-root?)? If so, are the amount of disk dpace used for the latter two sensible, or could/should they be adjusted?
