I have 4 hard disks (1 Tb each) on server.
It's debian wheezy, amd64. Disks 2,3 and 4 are not partitioned yet.
I have to join them into single partition, it must be single filesystem/mountpoint for web application.
What is there best way to do this: lvm, software raid md, or maybe exotic filesystems?
Also in case of using lvm or md, what is recommended filesystem? ext3, ext4, raiserfs?
