Hi,
The CentOS wiki sports a page about setting up software RAID1 on CentOS 5.x. There's a section about making both members of the RAID1 bootable by setting up GRUB on both disks.
Now I wonder how this should be done on CentOS 6.x and 7. I have two sandbox machines in my office, one running a minimal CentOS 6.6, the other one with a CentOS 7 installation.
Correct me if I'm wrong, but I guess the setup on CentOS 6.6 is similar to the one described on the wiki page for CentOS 5.x, something like:
grub> device (hd0) /dev/sda grub> device (hd1) /dev/sdb grub> root (hd0,0) grub> setup (hd0) grub> root (hd1,0) grub> setup (hd1) grub> quit
Now how would that work with the new GRUB2 under CentOS 7? Or maybe it's already installed on both disks, but how would I know that?
Cheers,
Niki
