I created the array with: sudo mdadm --create --verbose /dev/md0 --level=5 --raid-devices=3 /dev/sda /dev/sdb /dev/sdc
so you used the whole disks - what you shouldn't do at all
Yes I choose GPT intentional as each of the HDDs exceed 2TB but they did loose the "Linux RAID" Flag after the reboot
makes no sense when you use the whole disks in the create command - what you shouldn't do
ALWAYS use partitions and be it only if your replacement disk in a few years is for whatever reason a few kilobytes smaller
* partition the drive with GPT * make the patitions 5% smaller than the disk * use the partitions when create the array
