Disk space issues.

It's because the disks are assigned to a RAID array - do
cat /proc/mdstat
to see how they are assigned.

if you want to use the machine without RAID then you'll need to reinstall the OS and use custom partitioning to assign the space as you'd like.

Hello, i've noticed that i can use only 120gb instead of all 3 ssds (120gb each)
How can i use all of them?

When i try to load a partition:
[root@ns3362764 ~]# mount /dev/sda /sda
mount: /dev/sda is already mounted or /sda busy
When i type df -h>
[root@ns3362764 ~]# df -h
