Hi,

I've got a friend who is having some trouble with his Ubuntu server. 
It's running Ubuntu Bionic 18.04.6.

The setup is Ubuntu has multiple hard drives. The goal is to have the 
other hard drives be for storage of /home/* while the OS and most apps 
are all on the primary drive.

I wanted to make sure the system could actually see the other 
drives/partitions so I found under askubuntu.com that you can run lsblk 
command to see them in a nice human readable format:

chris at DM-02:~$ sudo lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT,LABEL

The extra drives are all there as sdb-sdp at 7.3T each in size. These 
need to be one drive as far as Ubuntu is concerned for the /home

I double checked with fdisk -l to make sure they showed as usable drives 
too and they do:

I've never done anything with logical drives which is what I believe I 
need to do in order to get these extra drives treated as one drive all 
for the /home directory for all users. So I'm just looking for 
assistance in getting that done.

Thanks!
