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? I asked this one month ago... nobody has encountered this or has any info?

Dunno, I just ignored it and put grub2 on it and it just worked without the --metadata flag. No tinkering or anything required. In fact, grub2 just worked like magic with default configs. So: "works for me" -- Sven-Hendrik
