I got physical dedicated server from one reputable server provider. And using their OS image install system i applied debian 6.x 64. Server has 2 SSD and one SATA. I setup software raid 1 during installation on SSDs but i dont see anything that looks like my HDD setup.. I mean server should contain: But this is df -h: I have been told that i need to mount 700+GB hdd: "add it to fstab our mount it manually via mount command" Can you please advice on how to proceed, how to do it properly so its mounted after each start? I thought Debian will setup disks automatically.
