Alienvault LVM partitioning

Alienvault by default installs just one partition and in some cases errors on some installations, by editing the preseed file you can split the partitioning up with LVM and avoid any errors. Best practice is to split up the filesystem in to separate sections so filling up /var does not corrupt the main root partition, doing this with LVM allows you to add extra disks later on. As Alienvault can store a lot of data, utilising LVM is extremely useful so you can expand your partitions on the fly later on.
