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?

One thought on - Preferred Partition Type For Raid 5

  • The preferred partition type is 0xfd, but that ONLY when building a RAID
    array from partitions. When building an array from whole disks (as you’ve done), the partition types on top of the array should reflect the contents of those partitions, so what you’ve got is correct.
