I ordered dedicated server with Linux Debian Wheezy preinstalled with "Paralles Plesk Panel". Provider states I have 2x1TB drives.

Yet my avaible disk space is just 100GB. Do I lack a partition? I don't know how to interpretate df -k the 79% usage where there's only 69 GB used as du -ch / shows.

Do I have all space avaible to use? If not how to set it?

i think you need to partition the 2x1TB drives. To do partitioning you need to use parted rather than doing with fdisk. Also post the o/p of mount command – ZVIK Oct 8 '13 at 5:52
As my question was put on hold, is it possible to move it to SuperUser SE site? I agree thats novice question. – Szymon Toda Oct 8 '13 at 15:52

You just need to create new partitions with the remaining space on the disks. If you are running raid then you need to create pairs of exact same sized partitions and add them to the raid. Here is the option list for fdisk(8)

$ sudo fdisk /dev/sda

Command (m for help): m
Command action
   a   toggle a bootable flag
   b   edit bsd disklabel
   c   toggle the dos compatibility flag
   d   delete a partition
   l   list known partition types
   m   print this menu
   n   add a new partition
   o   create a new empty DOS partition table
   p   print the partition table
   q   quit without saving changes
   s   create a new empty Sun disklabel
   t   change a partition's system id
   u   change display/entry units
   v   verify the partition table
   w   write table to disk and exit
   x   extra functionality (experts only)

Use the n-action to create a new partition and follow the on screen instructions. If you just want to create one partition with the remaining space the default values from fdisk will probably do, but be sure to be safe so you won't destroy the first/current partition. When you are done, use the w-action to write the table to disk and exit. You can now add the disks to raid or create a filesystem.

I dont run RAID. – Szymon Toda Oct 8 '13 at 6:07
@Ultra Then you can just create a filesystem with mkfs. E.g. mkfs -t ext4 /dev/sda2 – pkhamre Oct 8 '13 at 6:08
Doesn't it's filesystem needs to match already existing ext3 file system? And what about /dev/sdb ? :-) – Szymon Toda Oct 8 '13 at 6:09
If you are just creating a new filesystem it does not need to match anything. For /dev/sdb, do the same with mkfs. When you are done you can mount it, mount /dev/sda2 /some/mount/point or mount /dev/sdb2 /some/other/mount/point. – pkhamre Oct 8 '13 at 6:20
Every comment here helped me to discover useful commands (fdisk mainly) and use them to solve my problem. I had disk space but no partitions created. I have followed… to solve my issue – Szymon Toda Oct 8 '13 at 16:17
