Under Ubuntu 20.04, I have created a RAID0 with 5 drives. It is mounted, I changed owner to myself so I can write into it, and when I reboot I can access it from the terminal. Yet, it does not show anywhere in Nautilus. Here's what I did:
sudo mdadm --create --verbose /dev/md0 --level=0 --raid-devices=5 /dev/sda /dev/sdb /dev/sdc /dev/sdd /dev/sdesudo mkfs.ext4 -L DATA3 -F /dev/md0sudo mount /dev/md0 /mnt/data3sudo mdadm --detail --scan | sudo tee -a /etc/mdadm/mdadm.confsudo update-initramfs -usudo chown username:username /mnt/data3
In /etc/fstab
I added:
LABEL=DATA3 /dev/md0 /mnt/data3 ext4 defaults,nofail,discard 0 0
here's what things look like now with lsblk -o NAME,SIZE,FSTYPE,TYPE,MOUNTPOINT

Yet, nothing in Nautilus, not even in the "+other locations" where it shows without trouble another labeled drive (data2
) that was also in fstab.
