I have a Debian box that I am about to restore from backup since the old 2TB disk crashed and died.

So I have a new 3TB disk that will replace him, but when I filled the 3TB partition with the same data it actually seems to takes up more space, probably since there is a lot of small files.

Would it be more optimal to partition the drive in 2 or 3 primary partitions (size 1TB or 1.5TB) and use them as 1 LVM partition?

If it matters I plan to use ext4 on this disk.

maybe you've chosen the wrong cluster/inode size – Lưu Vĩnh Phúc Oct 2 '13 at 8:19

There shouldn't be any advantages to creating multiple physical partitions on the same disk and merging them together as one logical volume. It's just added complexity.
