I would like to emphasize issue No. 2.

Backup, Backup, Backup.

When you are doing it like this, LVM is a very good and flexible solution.

However, your intention is to distribute your data over two single 
disks, which are not mirrored ex. in a RAID configuration.

Now if only Disk of two fails, _ALL_ of your data will be gone. This is 
similar to RAID 0 in regard to data security.

So Backup, Backup, Backup

Kind regards
