[CentOS] Preferred partition type for raid 5

Hey All,

I my research I came across a note that a specific partition type was preferable when creating a raid 5 array. I installed my HDs and used mdadm to assemble them into a raid 5 array. I then partitioned the array using gdisk. The default partition type is "8300 Linux filesystem" for the two partitions that I created.

The article I read said that a specific partition type was preferred to avoid issues if the array was to be moved to another machine. Now I can't find where I read that.

What is the preferred partition type that I should use for my partitions?
