Depends on what place[12] are? In case of partitions, EVMS can't help you |
19 |
with that (at least not directly). You could create "place3" somewhere else |
20 |
(may even be a loopback device), and use EVMS's drive-linking feature to |
21 |
add the new space to "place1". |

Yes and no :-) It unites the whole volume management thing in a consistant |
36 |
way. That means, for some parts it is just a gui frontend. Other parts, |
37 |
like the drive linking feature, cluster manager or BBR plugin, are unique |
38 |
to EVMS. The good thing here is that you can combine those things, i.e. |
39 |
instead of creating an LVM container (volume group) on a partition |
40 |
directly, you could put the BBR (Bad Block Relocation) plugin in between. |
41 |
This you definitely can't do with bare LVM. The only thing that is missing |
42 |
up to now is dm-crypt support. |
43 |
|
44 |
Do you need to know the basics of LVM? IMHO it is better not to know the |
45 |
basics of LVM, even though EVMS uses it. But since EVMS is using a |
46 |
different terminology, it can be confusing. |
