[Newbie post] Ubuntu and multiple volumes - Have I made a horrible mistake?

[mahesh]

Windows systems engineer / General IT guy for 12 years + here. Made the jump to learning Linux a while back, passively, still struggling =|

The mission:
Supermicro Superserver with Ubuntu server 22 installed on an m.2 512gb. Virtualmin + WP + mariaDB (all configured waiting post hardening)
Raid5 with hotspare using 500gb SSD's (good quality Samsung 870Evo SSD's) [done]

When installing Ubuntu server, I chose a custom disk layout and made:

m.2 (512GB)


sdd 8:48 0 476.9G 0 disk
├─sdd1 8:49 0 1G 0 part /boot/efi
└─sdd2 8:50 0 475G 0 part /

r5 (ssd*4)
-\sda,sdb,sdc [raid presented as md126]
-├─md126 9:126 0 884.9G 0 raid5

md126 is mounted to \home


Now's the part where I'm not sure if I've screwed this up or not.

In my mind, mounting the raid5 volume to /home effectively means it's a symlink to another device, The idea being: have a separate volume for the websites data, which can grow to around 700GB, mounted as home so that wordpress hosts on virtualmin can have a home directory of a raid5 array (with HS) but the remainder of the files on the faster m.2 ssd.

Thoughts? or am I insane?
