I noticed today I tried to create a new system using 'Software / Fake RAID' on Arch with the 'mdadm' utility. I have not done this for a year or so but realized that when I tried now on my new system, it failed and then I tried it again and read between the lines... mdadm: Note: this array has metadata at the start and may not be suitable as a boot device. If you plan to store '/boot' on this device, please ensure that your boot-loader understands md/v1.x metadata, or use --metadata=0.90 So then I created my array as follows: mdadm --create /dev/md0 --metadata=0.90 --level=1 --raid-devices=2 /dev/sda2 /dev/sdb2 Is there a way to get Grub to read / access the default metadata that the 'mdadm' utility uses?
