is this big brained?

I've got HDDs of varying sizes (14TB, 24TB, 28TB) so I created a python script that partitions each one in 2TB increments, then creates a raid 5 from one parition from one disk each

then merging the various raid 5 arrays into a single Volume Group > Logical Volume > Filesystem (like how synology does it)

this allows me to grow each array flexably in the future if I was to add any hard drive size

It more complexity but beats the limitations of trueNAS and drawbacks of UNRAID and SHR
