How to use or combine Data disks in linux ubuntu 18.04

jp flag

Last year I bought a dedicated server from OVH for my Minecraft server because many of the Minecraft server creators was suggesting that I move to a dedicated server instead of shared hosting. I bought one, and these are the specs:

   
CPU Intel i7-6700K (4c/8t - 4 GHz/4.2 GHz)
RAM 32GB @ 2133 MHz
Storage 2× 480GB SSD SATA
1× 4TB HDD SATA

At that time, I ignored the data disks to focus on the RAM. As time went on, I learned about the df -h command and, when I checked I only saw 439GB on /dev/md3/, which is the root partition.

Disk Free Output

This doesn't seem right, though, because the server provider says that I have 2× 480GB SSDs and 1× 4TB HDD:

CLICK FOR IMAGE

This is the result of lsblk lsblk

My question is: how do I use the other 480GB SSD and also how do I use the 4TB HDD? Is it possible to combine the two 480GB SSD into the root?

Looking at the output, I would venture a guess that your two SSDs are configured in RAID0 and your 4TB disk is not formatted for use, so invisible to the file system. Can you [edit] your question to include the output of `sudo lsblk` and `sudo disk -l`? This will show information about your disks and partitions.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
