RAID home directory setup

I have ubuntu 24.04 LTS on a SSD. I setup a software RAID5 with 3 HDDs. The RAID is mounted on /mnt/md0 Here is my questions: I want the home directory to be in the RAID drives instead of the SSD. Basically, users would work from the RAID drives instead because the RAID drives have a lot more space. I have tried: 1. useradd -d to add new users in a home directory in /mnt/md0/home/user. But this created login issues, probably snap related, and Firefox doesn't like it. 2. Someone suggested me to mount /dev/md0, which is my RAID drives to /home. ubuntu REALLY doesn't like it and I couldn't even boot up again and I had to reinstall. What is the proper way to do it? Thank you edit 1: No I am not using LVM. Seems complicated.
