`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.
Defines the size of the `swap` volume. The default is the size of the
installed memory, minimum 4 GB and maximum 8 GB. The resulting value cannot
be greater than `hdsize/8`.
`maxroot`::
The `root` volume size. The `root` volume stores the whole operation

Defines the maximum size of the `root` volume, which stores the operation
system. The maximum limit of the `root` volume size is `hdsize/4`.
`maxvz`::
Define the size of the `data` volume.
Defines the maximum size of the `data` volume. The actual size of the `data`
volume is:
+
`datasize = hdsize - rootsize - swapsize - minfree`
+
Where `datasize` cannot be bigger than `maxvz`.
`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.
Defines the amount of free space left in LVM volume group `pve`.
With more than 128GB storage available the default is 16GB, else `hdsize/8`
will be used.

NOTE: LVM requires free space in the VG for snapshot creation (not
required for lvmthin snapshots).
