+Advanced LVM configuration options
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The installer creates a Volume Group (VG) called `pve`, and additional
+Logical Volumes (LVs) called `root`, `data` and `swap`. The size of
+those volumes can be controlled with:
+
+`hdsize`::
+
+Defines the total HD size to be used. This way you can save free
+space on the HD for further partitioning (i.e. for an additional PV
+and VG on the same hard disk that can be used for LVM storage).
+
+`swapsize`::
+
+To define the size of the `swap` volume. Default is the same size as
+installed RAM, with 4GB minimum and `hdsize/8` as maximum.
+
+`maxroot`::
+
+The `root` volume size. The `root` volume stores the whole operation
+system.
+
+`maxvz`::
+
+Define the size of the `data` volume, which is mounted at
+'/var/lib/vz'.
+
+`minfree`::
+
+To define the amount of free space left in LVM volume group `pve`.
+16GB is the default if storage available > 128GB, `hdsize/8` otherwise.
++
+NOTE: LVM requires free space in the VG for snapshot creation (not
+required for lvmthin snapshots).

+
+ZFS Performance Tips
+^^^^^^^^^^^^^^^^^^^^
+
+ZFS uses a lot of memory, so it is best to add additional 8-16GB RAM
+if you want to use ZFS.
+
+ZFS also provides the feature to use a fast SSD drive as write cache. The
+write cache is called the ZFS Intent Log (ZIL). You can add that after
+installation using the following command:
+
+ zpool add <pool-name> log </dev/path_to_fast_ssd>
