Depends on what place[12] are? In case of partitions, EVMS can't help you
with that (at least not directly). You could create "place3" somewhere else
(may even be a loopback device), and use EVMS's drive-linking feature to
add the new space to "place1".

Yes and no :-) It unites the whole volume management thing in a consistant
way. That means, for some parts it is just a gui frontend. Other parts,
like the drive linking feature, cluster manager or BBR plugin, are unique
to EVMS. The good thing here is that you can combine those things, i.e.
instead of creating an LVM container (volume group) on a partition
directly, you could put the BBR (Bad Block Relocation) plugin in between.
This you definitely can't do with bare LVM. The only thing that is missing
up to now is dm-crypt support.
Do you need to know the basics of LVM? IMHO it is better not to know the
basics of LVM, even though EVMS uses it. But since EVMS is using a
different terminology, it can be confusing.
