The manpage of open(2):
There is one exception: on Linux 2.6 and later, O_EXCL can be used
without O_CREAT if pathname refers to a block device. If the block
device is in use by the system (e.g., mounted), open() fails with the
error EBUSY.
Even when disk has partitions, when all partitions are not used, this
function still treats it as free disk.
When specific disk or its partition is used by LVM, if there is no data
stored in it, this function still treats it as free disk.

Return a list of lsm.Volume objects.
Unused here means the LUN/volume meets one of following conditions:
* the block device representing LUN/Volume could be opened with O_EXCL,
which means its block is completely free.
* The block device is used as PV of LVM, but not been used.
