How do I use available hard drives in this system?
0
I am not very experienced Ubuntu user, and I have an Ubuntu server to use for some calculations. The server has several hard drives and SSD-s. The hard drive seems to be in RAID 5 set up.
The thing that confuses me is available disk space:
Filesystem Size Used Avail Use% Mounted on
udev 189G 0 189G 0% /dev
tmpfs 38G 2.8M 38G 1% /run
/dev/sda2 880G 205G 630G 25% /
tmpfs 189G 36K 189G 1% /dev/shm
tmpfs 5.0M 4.0K 5.0M 1% /run/lock
tmpfs 189G 0 189G 0% /sys/fs/cgroup
/dev/loop0 87M 87M 0 100% /snap/core/4917
tmpfs 38G 52K 38G 1% /run/user/1000
to me it seems like /dev/sda2 is main partition to store files and it belongs to one SSD. So if I will fill system with files on 630 GB I'll run out of space.

I tried to create new partition on /dev/sdb and it was successful. But when I tried to format it with sudo mkfs -t ext4 /dev/sdb1 system tells me that partition apparently in use by the system and this new partition is not displayed in df -h output.
Can someone explain set up of this system and how do I proceed? I do not really understand how do I use RAID5 hard drives and SSDs.

Did you get an error if you doblockdev --rereadpt /dev/sdb, this is used to refresh partition table of a drive.

Did you get an error if you doblockdev --rereadpt /dev/sdb, this is used to refresh partition table of a drive.
