volume group (logical volume...) on duo v2 ?
Hi all,
Just one question about my duo v2 : why netgear doesn't propose a simple volume group (logical volume...) to obtain one store unit from 2 hard disk without disadvantage of the raid0 (distributed data, so if one disk died, all data is lost). Moreover, it's on the network, so the raid0 capacity is limited by the transmition's rapidity, isn't it ?
Thx and sry for my english...

- If I don't misunderstand, you can use raid1. Then the data is redundant.
- I think he wants a spanning volume that is not striped. So that it would (a) not have redundancy (b) present itself as one volume, and (c) would still preserve ~half the files if a drive fails.
The existing jbod mode more-or-less does what he wants, it just presents as two volumes to the admin. Everyone else just sees shares of course.
I think that the current jbod scheme makes it easier to replace disks/restore the data. The spanning volume idea on the other hand eliminates the need to balance free space between the drives.
