You basically setup a PV volume spanning the whole drive(s), and then a 10GB (or larger if you need to) LVM volume for /root, 10GB for /var, 2GB for /tmp & 5GB for /home. Then for any VM's just add LVM volumes as needed, for example: /dev/Volume001/vm1_root - 10GB /dev/Volume001/vm1_swap - 1GB Another tip: Don't use the default LVM volume naming scheme, but instead name the LVM volumes according to your server name, i.e. server01 & server02. This way if server01's HDD crashes and you need to mount it on server002 for recovery purposes, you won't have conflicting LVM volumes -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532
